Re: TSM performance very poor, Recovery log is being pinned

2007-07-27 Thread Craig Ross
Thanks for all input guys,

Firstly sorry for lack of detail.

TSM is installed on Solaris 10, No I did not do any benchmarking, as we were
not replacing any existing setup just adding more, I have 6 LTO drives
already installed and about 17TB of SAN storage which is Primary Random, I
have since added 4 new LTO 3 drives (with different Device classes) and they
run better than the LTO 1 drives, when server is not logpinning. And the new
15 TB of SATA, now approx 1 TB of the DISK is Primary Random storage and the
remainder is SEQ file and its all FS not RAW, I have had heavy discussion
over RAW vs FS and I have not been able to find definitive answer

Clients I don;t think are causing the issue any TSM processes can pin the
log from migrations DB backups and clients sessions. Once the server starts
getting busy.

Currently (sorry not in front of installation) but I guess of the 15TB I
have about 60 sequential volumes across 4 Stgpools, and I have still more to
define.

I have not had clients utilize this new storage yet, all I have done is
start to migrate data into these STGPools to release some of the legacy
STGpools


 The Transport to DB and Recovery Log is SAN, however yesterday I created
local copy and this did not improve things.

The STGpools are on WMS SAN and AMS500 SAN. Both SATA disk. All across
Fibre!!


 The SAN engineer when installing the Disk's saw expected performance out of
the DISK's.

I also don't see it being maxsessions because I can Pin the log with 3 or 4
sessions and 3 processes!


 I think its safe to say its configuration somewhere, because now I think
about it its not taking much load to pin the log. Load in which TSM normally
copes ok!!

Next step may be to remove the New DISK's now will I need to just unmount
the FS or will i Need to migrate data off new storage and delete volumes and
New STGpools?

Thanks

   In your comparison, you may want to include option #3 - tar (unix)
and backup (Windows).  The software cost is incredibly low and there
should be zero compatibility issues with the installed operating systems

Kelly,
Thank you for your post.  There is no reason to say we are
unhappy with TSM.  Since I inherited this environment about a year ago,
due to lots of hardware and software version upgrades, and help from the
Windows and AIX teams, our daily backup completion status (neither
missed nor failed)has gone from 95% to 99%.  That is less than 10 out of
the ~1000 clients daily, which is quite good by industry standards.
No, according to management, cost is the driving factor.  The
proposals between IBM and it's closest competitor are, over a total
three year cost, umpteen thousand dollars apart (I won't say the exact
figure).  It is enough to make everybody take notice.  
Of course, no one has figured in the cost of conversion, both in
software and manpower.  That will be huge.  Not to mention the huge
distraction and lost opportunity cost and risk of outages that could
result.\I agree that IBM ought to go back and sharpen their
pencil, and bargain away this threat to their territory.

I also think there is a golden opportunity to work with your current

The real funny thing is that at the end of the day, the cost (when done

Interesting. We are doing the same thing, but with multiple vendors, for
the EXACT same reason you are. We are generating a single RFI that we
will send to each vendor, and get our comparison that way. Not done yet,
and I'm not looking forward to it. I like TSM as a product, and I'm not
looking forward to a possible migration, 'cause like you said, there
will be a cost associated with it (more media/drives?, hardware, fill in

We are supposed to be talking with EMC soon, and have already talked to

Greetings,
We have been a TSM shop for many years, but EMC came to our
management with a proposal to replace our TSM licenses with Legato
Networker, at a better price than what we are paying for TSM today. This
came right on the heels of paying our large TSM license bill, and so it
got management's attention.
We have an infrastructure of 15 TSM servers and about 1000
clients, so this would be a large and painful migration.  It would also
require a great deal of new hardware and consultant costs during the
migration, which would detract from the cost savings.
So instead of jumping from one backup product to another based
on price alone, we have been asked to do an evaluation between the two
products.  Do any of you have any feature comparisons between the two
products that would give me a head start?

Re: TSM vs. Legato Networker Comparison

2007-07-27 Thread Schneider, John
Stuart,
Thanks for your excellent point.  One thing that frequently
determines the reputation of a backup product within a company is the
quality of the hardware it is running on, and the skillset of the people
managing it.  
We had one remote location with an old LTO1 tape library,
running TSM 5.1 on a 700MHz Pentium II Win2K box with a 10/100 card, and
the people supporting it hated TSM because "this TSM server is always
having problems".  We have since upgraded it to a new IBM LTO3 library
and a CDL 210, running TSM 5.3.4.2 on a new Win2003 server with dual
3.2Ghz Xeons w/GigE, and all the problems have gone away.  Now the
people who monitor it have nothing to complain about, so they complain
about our Exchange servers instead!  Time to upgrade those next, I
guess.

Funny you say this. Monash was a Legato (now owned by EMC) shop until
the TSM migration around 3-4 years ago; I suspect that a large number of
the problems that were perceived to be Networker's fault were actually
the fault of the aging DLT silos and drives that underlay Networker. I
still have fond memories of those silos; they gave me a great deal of
callout pay every time they had a stuck cartridge or similar. :-)

I also suspect that the greater reliability we've had since putting in
TSM is more because we also got in new tape silos (LTO2, now half LTO2
and half LTO3, and soon to be half LTO3 and half LTO4) - if we'd stuck
with the DLT silos, we'd still be in a world of pain, regardless of the
software.

There are plusses and minuses to both products. Some points to consider:

   * Networker uses the traditional "full plus incrementals, or dump
levels" system. Monash used a pattern of "full once a month; incremental
every other day; and a dump level interwoven" - so, for example, it
might go "full, incremental, level 8, incremental, level 7, incremental,
level 9, level 2, incremental, level 8, incremental, etc." - the idea
being to minimise the number of backups needed to restore a system.
   * Networker indexes are somewhat analogous to the TSM database. In
theory, you can scan each tape to rebuild the indexes if they're lost;
in practice, if you lose the indexes, you're pretty much dead - there's
just too much data to scan if the system is more than moderately sized.
Yes, Networker backs up the indexes each day. :)
   * At least the versions of Networker (up to 7.x) we used doesn't
support the idea of staging to disk - everything goes directly to tape.
However, data streams from multiple clients are multiplexed onto tape to
get the write speeds up. This is good for backups, but does make
recovery slower (since the data read will include a lot of data for
other clients.)
   * No more reclamation or copy pools to deal with (because of the
traditional full/incremental/dump level system). So the burden placed on
the tape drives is probably going to be significantly lower (although
you will be backing up more data each night than you would with TSM.)
   * I don't think Networker has anything analogous to TSM's scratch
pool: volumes belong to a pool of tapes, and there's no shuffling
between the pool. So if the "standard" pool has a hundred tapes
available for use, but the "database" pool is out of tapes and needs one
more, you need to manually intervene. This *may* have been because of
the way we configured Networker, though, and it may also have changed in
the interim. Note that you *have* to have a separate pool of tapes for
index backups.

My honest assessment mirrors that of the other people who have
replied: use this as an opportunity to negotiate better pricing from
IBM, and point out to the powers that be that there are risks involved
with moving to a different backup product. There's nothing wrong with
Networker, it's a good syste

Re: TSM performance very poor, Recovery log is being pinned

2007-07-27 Thread Ian-IT Smith
Do the client backup sessions pin the log? What is the throughput on the
actual client session and are these backups direct to disk? If the
sessions are cancelled does the system come back to life?

15 TB of SATA sounds like a lot of storage. how has this been
added/configured- What raw throughput do you get on these disks outside of
TSM itself?

You say the LTO3 drives are new. Do you have existing LTO3 drives? Have
you configured them correctly with new device class etc if you are mixing
LTO generations in the library?

I have seen this type of pinning/dramatic slow down before. I saw itself
manifest by the server hitting the maxsessions limit as all the sessions
were running so slowly to the disk pool.

Lots of questions i know, but as you have made multiple changes at the

Re: New policy domain

2007-07-27 Thread CAYE PIERRE
It depends of the name of management class in the new domain.

For backup copy groups, if TSM find a mgmt class with the same name in the new 
domain (and with a backup copy group within...), it will rebind objects to the 
new  policies
If not, it will rebind object to the default mgmt class

I think it's the same for archive copy groups but check that to be sure...

New policy domain

2007-07-27 Thread Wayne Prasek
Hi everyone,

I have a few quick question regarding changing policy domains.  I looked
through the admin guide but it didn't clear all my questions up.  We are
still running 5.2 (soon to be 5.3).

We need to change a few clients to start using a completely new policy
domain which includes a new storage pool and retention periods.. etc
etc.  Once we change the clients policy domain what exactly happens to
the existing data in the old policy domain?  Will remain active and
expire as usual?  What will happen the next time the clients get backed
up?  Will it do a full incremental backup?

Re: TSM DB backup question

2007-07-27 Thread Nicholas Rodolfich
Sorry for the confusion here all.

I have sent out a reponse to this post earlier this AM, but it is
taking a while to post. Looks like you responded to it below. I am not
sure why this is not included in the post. I will try posting it again.

FYI, the file system is a large file enabled JFS2 and filesize is set
to unlimited. I created a file larger than 64Gb with AIX on the
filesystem with no problems. IBM says this is a TSM limitation not an
AIX one and they have an APAR associated with it (see link below)

---
Again im sorry, this was my mistake, I miss understood what my
colleague had told me. Indeed AIX its self will work with file spaces
larger than 64g BUT As per the APAR I linked you...

http://www-1.ibm.com/support/docview.wss?uid=swg1IC50581

The 64g is a known limitation of TSM on AIX systems. As such TSM will
only recognize up to 64g of space on a FILE type space. I have found
further information confirming this in another PMR. As shown on the
bottom of the APAR, this problem will be fixed in a future release.

Does this answer your question? is there anything else I can help you
with?

An old gotcha on AIX was the ulimits file. Limiting the filesize any user
could create. Also if the filesystem was large file enabled for files over
2 GB.

These are quite old issues though.

Re: TSM performance very poor, Recovery log is being pinned

2007-07-27 Thread Joy Hanna
You might also check your diskpool volume count. If its low, assuming
your doing raw logical volumes, you might want to try decreasing the
size of your volumes and thereby increasing the count of your volumes .
A small number of large volumes does not allow several clients or
processes to stream data to the storage pools efficiently.

You need to provide more information than that.  I'm not aware of any
file system which allows a file of infinite size.

A file system characteristically limits file size according to file
system architecture and the current operating system instance
bitmode.  For example, JFS in a 32-bit AIX kernel limits file size to
64 MB.  And, naturally, a smaller partition size will impose a lesser
ceiling.

You need to take a look at your OS/fs configuration there, as the TSM
manual says.

Re: [ADSM-L] 6 vs 8 character LTO2 volser - do I care ?






With TSM server on an AIX platform with LTO, there is an option

As long as you're not putting previously labeled tapes into the new
library, you should be good to go. If you're putting in previously
labeled tapes with no data on them (scratch tapes), you'll need to force
a relabel. If the tapes have data on them, you're in for a hell of a
time; you cannot force a relabel without rendering the data unreachable.

Hi All,

Thanks for your help!!

In my daily maintenance schedule I am doing a database backup to disk
with the following call and using the following device class. When the
backup runs it writes a second file apparently after it completes the
DB
backup.  I wouldn't be concerned except the extra file shows up in my
volume history as seen below (which I did not expect). Notice the
entry
for the second file has the same Backup Series as the first file. It
looks like TSM is writing a second volume since the Volume Sequence is
2, but I dont know why!

NOW I SEE IT!  The Est/Max Capacity (MB): 61,440.0 is getting me. I
created this device class and I don't remember putting a size on it
but
I guess I did. Anyway, when I try to change it to 8Mb TSM tells
me:

---

Thanks for the tip.

Since I really needed to get moving on this, I am simply letting the new 
Library Manager server reinitialize the tapes as 8-chars as needed. This 
way I will recreate the offsite pool, fresh, and avoid the long list of 
reclaims that are constantly waiting due to lack of drives/time.  Since 
these are only offsite copypool tapes, they aren't very critical (at least 
not for me).

You can adjust the volser reporting on the Library, which is the safer way 
to control volser reporting.

On the main menu => more =>  Setup => Library => MEDIA

The you choose the volser reporting 8 char or 6 char.

After that, you will never bother with volser mode, and you don't have to 
manage it through special files of your OS

Then you will have to re label all that tapes originally labeled with 8 
char labels.

I hope some are not already used...

Re: Sharing a 3583 library

2007-07-27 Thread Zoltan Forray/AC/VCU
No, that is not what I meant. I realize I will eventually need to
reconfigure all of the TSM servers. I just wanted to reconfigure in an
optimal way or was hoping to not have to drag drives from one library
manager to another and possibly back and forth, if needed.

As I mentioned, I was hoping for some "smart" sharing of devices since TSM
does manage the drive usage.

As for the 6/8 volsers, I am just letting the new LM server reinitialize
the tapes as 8-chars.

So if I understand you correctly, you will eventually be moving the
library management completely to the new server, but you want to
avoid reconfiguring all the existing TSM instances?

I've just completed moving two library managers from one TSM instance
to another (the "new" manager is dedicated solely to library and
configuration management, where the "old" managers also served backup
duties.) It turned out to be remarkably easy:

   * Delete the old paths, drive definitions and library definition
on the old library manager (and the new library manager if it's
currently a library client).
   * Define the library, drives, and paths on the new library manager
(setting the drives to offline, so no tapes are accessed until you're
finished.)
   * Checkin the libvols on the new library manager (CHECKIN LIBVOL X
search=yes stat=scratch checkl=barcode)
   * Update the old library clients (UPDATE LIBRARY X
PRIM=new_lib_manager on all instances)
   * Create a library definition on the old library managed (of type
shared, pointing at the new library manager.)
   * Run an AUDIT LIBRARY on the library clients (including the old
library manager).
   * Set the drives to online, and you're away.

The audit on each client will set tapes with data to private status,
owned by the relevant client. If you're paranoid about this, check
them in as private, owned by the new library manager, and make a note
of the scratch volumes known by the old library manager before
deleting the library definition (query libvol). The audit will update
the ownership to the correct node, you can manually update the
remaining volumes to be scratch, and chase up the remaining volumes
owned by the new library manager (assuming it didn't own any volumes
beforehand) as potentially orphaned - we found some 30 tapes that
should have been returned to scratch by the clients, but the library
manager hadn't updated them for some reason so they were still marked
as being private.

As for the 6/8 character volume label: I can't speak for a 3583, but
we're using a pair of 3584 libraries. In the web-based management
system, there's a section for "Library", "Logical Libraries"; have a
look at the "modify volser reporting" option - it might help. Note
that this will likely affect *all* volumes, so if you have data
stored on volumes with a mix of 8/6 volume serial numbers, you're in
trouble ...

Hope this helps.

TDP for Exchange - poor performance during online backup

2007-07-27 Thread Ronald A. Hammer
I'm running Exchange Version 6.5.7638.1 under W2k3 Sever with TDP for
Exchange 5.3.3.

Running an online backup it starts with a data rate of aprx. 10 MB/sec.
After some minutes this rate slows down to aprx. 1 MB/sec. The effect of
this is, that a backup of aprx. 90 GB of data will last aprx. 30 hours.

Does any body have an idea what's the reason for that strange behavior.


Thanks
Ron


Re: TSM performance very poor, Recovery log is being pinned

2007-07-27 Thread Richard Sims

Craig -

You need to perform analysis to identify problem cause, where the TSM
Problem Determination Guide and Performance Tuning Guide will help.

Log pinning is due to prolonged transactions, and is aggravated by
sluggish networking and sluggish TSM servicing of transactions (often
due to underlying disk/tape issues).

You can quickly see if your TSM server is "behind" in its rate of
servicing incoming client data by inspecting the TCP receive queue
packets backlog.  In AIX that can be done via the command:
  netstat | head -2 ; netstat | grep -vi dns | grep tcp
If the various entries show a large receive queue value, then it is
likely that your networking is good, but that TSM is not keeping up
with the incoming, as may be caused by the underlying disk, tape, and
I/O path technology that it is using.

If your clients have recently started backing up very large files
(digital movies is a stereotypical case), then that would certainly
contribute to what you're seeing.  A quick look at TSM accounting
data or ANE Activity Log messages would give a sense of that, and
Query CONTent with a negative Count value on the collocated tape
volumes that the clients are doing will show biggies.  Query SESSion
during client activity will also help identify consumptive sessions.

Before you gave TSM the new LTO 3 and SATA hardware, I would hope
that you benchmarked it first, to assure that it was providing the
performance you would need in production, and thus uncover any issues
with it beforehand.  A bad RAID choice in disk implementation will
also slow throughput.  Old microcode may have performance-impairing
defects.  A mismatched device driver can cause operational delays.

Don't waste your time or jeopardize your server in doing a TSM db
unload/reload.

You may want to confer with your operating system people to have them
help narrow down the problem area, where they are familiar with all
the specifics of your environment.

   Richard Sims

The DB is approx 90GB TSM

Few days ago I noticed processing had ground to halt, after digging around I
have found as soon as server gets busy maybe 4 processes 8 or so sessions
the recovery log begins "sh logpinned" to pin and the Database gets locks.
Shown by running "sh locks"
And as result the server suffers!
Now today I have stopped using the new Tech LTO 3 and SATA and things are
coping better but still worse than previous as soon as load is increased Log
pins and processing slows drastically.

Are there any steps I can take which will help my scenario.
Would a DB UNLOAD RELOAD help that much?

Reference: Recovery log has heaps of room DB has heaps of room 90Gb DB with
100GB of room.

Any advice is much appreciated.
