Yes, where cartirdge is FULL its estimated capacity is the real capacity.
And if you have some files already expired the percentage will be less than
100. In other words if tape fills and then data on it expire it will reach
100% and later decrease. If expiration happens before tape gets filled you
will never get 100%.

query occupancy - no of files in primary/copy storage pool

[Waern Maria]

Hi

I've noticed a discrepancy in the "number of files" value for a primary and
copy storage pool.  The "number of files" value in the copy storage pool is
much lower than for the primary.  The total space occupied, however, is
basically the same in both.  Why the differing values for "number of files"
values then?

Thanks

Re: Journaling

[Pete Tanenhaus]

The primary difference between traditional progressive incremental backup
and journal based backup is the method
in which the client uses to determine what objects to backup or expire.

Progressive incremental backup obtains the backup candidate list by
building and comparing the list of active previously
backed up objects stored on the TSM server with the list of objects
currently residing on the local filesystem.

The local object list is built by scanning the entire file system, the
server list is received over the network, and the candidate list is
built by comparing the two lists.

All three lists reside in memory until the backup is completed.

Journal based backup derives the backup candidate list by contacting the
TSM journal daemon and processing the contents
of the particular file system journal.

The journal daemon is local process (service) which maintains journal
databases for specified filesystems by monitoring
the file system for change activity.

The performance saving in terms of both memory, i/o, and network traffic
for journal based backup is that only objects which
are actually backed up/expired are processed, whereas progressive
incremental has to process the entire file system.

So  the benefit is really only realized when backing up file systems with a
very large number of objects with a small to moderate
amount of daily change activity (for example, a file server with 2 million
objects of which only about 5% to 10% change daily).

Smaller file systems which have high volumes of change activity probably
will not see that dramatic of an improvement
over traditional progressive incremental backup

Re: Journaling

[Gerald Wichmann]

Great for systems with lots of files.. Ran some tests backing up a win2k
server with a million files before and after journaling option was enabled.
Without it enabled it took an hour just to scan through the directory
structure even if nothing needed backing up. With it enabled, the hour-long
backup took less then 5 minutes.. Haven't run into any problems using it
myself but I can't say I've used it extensively (just on a server with lots
of files).

Re: BEST WAY to MIGRATE TO NEW DEVICE CLASS

[MC Matt Cooper (2838)]

What I am trying to accomplish is changing the COPYPOOL to use the
same DEVICECLASS as the TAPEPOOL.  Right now they are using the same tape
drives but different device classes so that the high level qualifiers were
different.  On our z/OS system we use CA-1 for tape management.  The easiest
and most consistent way to handle tape vaulting and all the associated
reports that go with it, was to use high level qualifiers, (as is the case
with the rest of the products on the mainframe).   Doing that rendered TSM
priority handling useless.  I know I can now use some additional work keying
on when I am telling TSM what tapes to mark OFFSTE to also tell CA-1 to give
those tapes an OUTCODE and OUTDATE.  This will drive the vault handling
properly for CA-1.  I never thought I wouldn't be able to migrate to this
new setup in an orderly fashion.

Well, if you have really reached the conclusion that you need a new
devclass,
you have really limited your options.

Look at it this way: A new devclass is like a new library.  If you need to
move all your data from library A to library B, you're going to do a lot of
copying.

major reorganizations of data storage like this just take a long time;
that's
all there is to it.


If what you're doing is (for example) just changing all your 3590Bs to Es,
then you might get away with deleting all the DRIVEs from your old library,
and then re-adding them with the new specifications.  In this case, you're
not
generating a new devclass at all.  This is a pretty standard step in the
upgrade from a B to an E infrastructure.

If you do this, remember to set all your B volumes to read-only.

HSM is a real nice solution in High performance environments where users
create lots of data, want to keep it forever, but do not want to be bothered
with learning how to use archiving. It is still a lot cheaper than diskspace
in a really fast storage array.

BEST WAY to MIGRATE TO NEW DEVICE CLASS

[MC Matt Cooper (2838)]

Hello all,
   I am in a situation where I want to migrate a COPYPOOL to a
different DEVICE CLASS.  (I would settle for a change to the high level
qualifier on the tape but that can not be done.)I asked TSM and they
said that I have to define a new COPYPOOL, associate it with the new DEVICE
CLASS and do BACKUP primary pool to COPYPOOL until it has all been copied.
I have 10 TB of data in the COPYPOOL and I am running on z/OS.  Which means
I am usually busy during 1st and half of 2nd  shift.  Either way it would
take a week of dedicated tape to tape activity (3 processes at 20GB/hr each)
to do.
DOES ANYONE HAVE A WAY AROUND THIS?   OR A SUGGESTED COARSE OF
ACTION?

Re: opinion on AIT vs LTO and 3570 tape technology?

[Paul Zarnowski]

Lisa,

We went through this exercise ourselves about 6 months ago.  AIT does look
good on paper, with it's faster access times.

Salak made the point,
>Ait access time really shine when the chip on tape is supported by the
>application.  You may want to check whether TSM supports it.

TSM does not support this chip, at least not in the way that would exploit
the faster access times.  Before counting on these faster access times, I
would find some real-life data with TSM.

As far as scalable libraries, ADIC supports multi-media, including both LTO
and AIT.  Their libraries are quite nice, and scale higher than the 3584.

The decision point for us, tho, was that we could not find sites using AIT
that had the level of high usage that our site has.  The couple that we did
find had run into some problems, some of which were startup problems that
were resolved and some of which were ongoing.  If you are looking at high
duty-cycles, I would look at this issue more closely.  I believe that the
IBM LTO drives in particular, are more robustly manufactured than the Sony
AIT drives or the non-IBM LTO drives.  Like Don said, the IBM LTO drives
seem to getting a high acceptance rate in general, and within the TSM
community.  While you don't hear too many AIT problems in the TSM
community, I don't believe they are used as widely, especially in
high-usage environments.  All tape technology has some problems.

We opted to go with an ADIC Scalar 1 with IBM LTO drives.  The ADIC
library gives us the option of changing tape technologies down the road, if
something better comes along.

The HSM issue is not a matter of the number of files and directories, but
rather an issue of frequency of access. If the files are generated and then
rarely accessed, HSM would make sense, given if the following is true:

1. The customer is *really* tight on disk space, and
2. The files are infrequently accessed, but need to be immediately
available.

HSM is a more complex issue if you're dealing with Windows client boxes.
You'll have to look at a solution like OTG DiskXtender for non-UNIX clients.

HSM actually doesn't make a lot of sense, in these days where disk space is
not much more expensive than tape space.

Re: Backup ends after filling one virtual volume

[J. Gehm]

In the meantime I found the solution for my problem and so I anwser to my
own request:

The REGISTER NODE command have a new parameter MAXNUMMP under TSM 4, with
a default MAXNUMMP=1. My new configured servernodes could not mount more
than 1 Tape. The servernode, which I configured under TSM 3.7, got a
MAXNUMP "Unlimited" with the upgrade to TSM 4.1.

A backup on virtual volumes needs 2 drives, when MAXCAPACITY is reached
and the last file is continued on the next volume.

Re: Unix clients

[Zlatko Krastev]

Lindy,

you have defined DSM_CONFIG environment variable (which should point to
dsm.opt) with directory only. In all flavours of UNIX directory is just a
specially interpretted file (and you can read it as a file). DSM_DIR
should point to *directory* where dsm.sys resides but DSM_CONFIG should
point the dsm.opt *file*.
And have a look also is it defined with  in bin
(/usr/tivoli/tsm/client/ba/bin ???) or is mistyped in your mail
due to copy/paste.

Re: Compression

[Zlatko Krastev]

Yes, where cartirdge is FULL its estimated capacity is the real capacity.
And if you have some files already expired the percentage will be less
than 100. In other words if tape fills and then data on it expire it will
reach 100% and later decrease. If expiration happens before tape gets
filled you will never get 100%.

Subject:Re: Compression

If a cartridge is FULL, does the estimated capacity include files that
have
been expired on that cartridge? E.g. assuming a tape takes time to fill
up,
it's possible some of the files on that tape may expire before the tape
reaches FULL status. It's also unlikely the space has yet been reclaimed.
Once the tape reaches FULL status does the estimated capacity include
those
files that have expired?

Divide the amount of data on your FULL tape volumes by the native
capacity.
Here's a sample SQL statement. You'll need to filter it for your tape
storagepools and only FULL volumes.

select volume_name,cast(est_capacity_mb/ as decimal(3,1)) from volumes

Use these values for :

3590B   10240 (10GB native)
3590E   20480 (20GB native)

Extended length cartriges double the value.

LTO Cleaning Cartridge

Hi *SM'er ;)

Just a question: How often can an LTO Cleaning Cartridge (IBM) be used. I
wonder why this is not mentioned on the product.


Thanks in advance
