Without knowing the kind of restoral you were performing or its

(disk/file system configuration, collocation, tape drive type and model,
etc.)
we can only offer general suggestions.  In that you were running multiple
restore sessions at a time, certainly waiting for tape dismount and mount

be aggravated.  In http://people.bu.edu/rbs/ADSM.QuickFacts topic "Restoral

Gurus don't use GUIs, but they can still advise on this...  :-)
In that all the gurus are off-duty at this hour, I'll take a stab at it.
The preference would seem to correspond to the INCRTHreshold option, introduced
in TSM 4.2.  See the description of that option in the Windows client manual,
which gives the basic explanation.  As always, a full explanation can be found
in the redbook which explains all the new features in the version-release: i.e.,
the TSM 4.2 Technical Guide.

Re: newbie: device drivers on win2k

[Chris Murphy]

>What is the proper method of using device drivers on win2k

Hi Jon,

Crack open that 'ol Administrator's Guide, Part2, Chapter 4.  There is a
section called "Selecting a device driver" that explains this process.
Normally, if you are not using RSSM, have non-IBM tape libraries and have
hardware on the "supported" list, you will want to use the TSM device
driver.  This sounds like your situation.  HTH!

TSM and mod-27 devices

[Sam Sheppard]

Well, I'll take a stab at this.  We just converted from an old RVA to
an ESS-800 and wondered the same thing.  General agreement seemed to be
there weren't really any advantages to mod-27 unless you're running out
of addresses and there were some downsides, mainly the inability to
start more than one I/O to the device at a time without PAV. I'm not
really sure what kind of problems you might see, performancewise. Might
be OK.  There is also the size limitations on the log/db which would
prevent you from using the entire 25GB with one dataset.

There are probably other considerations, but we had no reason not to
just stick to lots of mod-3s.

I know I asked the same thing here about a month ago and didn't get
much feedback.  Anyone else tried this?

'threshhold for incremental backups'

[Coats, Jack]

OH TSM gurus, :)

I read the help, but what does this stand for in the gui client, setting
preferences,
there is a filed that is called 'Threshold for non-journaled incremental
backups'?
It takes a value of 0 to 200,000 and after reading the helps the meaning
still does
not sink in.

Is this the number of files changed before it dumps the local journal of
directory
entries before it does a backup where it checks each files status against
the
TSM server database?  Or what?

following:
Compaq Secure Path device driver does not work in 64bit mode, unless you
de/re-install it in 64 bit mode

There is an apar for network latency on AIX 5.1.x that needs to be applied

Hey all-

Bear with meI'm not solaris savvy one...

I'm trying out the solaris 5.15 client for the first time here and ran into
a question that I need help on:
Here is the dsm.opt file:
SERVERNAME AIXTSM2

is "ufs" and all other file systems are veritas file systems (vxfs) I i'm
trying to sort out if I have a syntax error in the dsm.opt file.
   Here are ufs file systems:
/dev/vx/dsk/rootvol /
/dev/vx/dsk/var /var
/dev/vx/dsk/opt /opt
/dev/vx/dsk/home01  /home01

Re: AIX Upgrade from 4.3.3 to 5.1

[Miles Purdy]

The only thing I would recommend is that you uninstall Atape, reboot, install Atape, 
reboot. Especially if you enable the 64-bit kernel. Actually Atape would not work 
after I just enabled the 64-bit kernel. You can search the list for my posting about a 
month ago.

newbie: device drivers on win2k

[jonlists]

I'm fairly new at TSM, have a small test server setup so I can learn more
about the product however, I'm struggling a little bit with Win2k
device drivers - the services mix.

>From my understanding, you want to use Tivoli native drivers. However, if
I disable the win2k native device driver, the backup gui just sits,
waiting for media forever, so it's clearly not communicating with the
native device driver.

If I use the win2k native driver, it seems to back up fine, but
performance is abysmal.

removable storage service on win2k is disabled.

drive is DLT VS80

tsm is 5.2

What is the proper method of using device drivers on win2k

Re: 3584 Tape Sharing

[Zlatko Krastev]

Hi Tim,

I am lagging the list but will try to help with this one.
Partitioning was discussed and your assumtions are correct. No need to
discuss it.
Library Sharing - I've found no word about "Library Sharing over LAN",
only "Library Sharing in a SAN"! Maybe you are misled by some info
regarding LAN-controlled libraries like 3494 (I am just guessing).
You can use twin-tail SCSI (LVD supports it) and put two initiator
devices/SCSI controllers on the SCSI bus. SAN does the same but over
fibre. After you can access drives and robot from both hosts, read the SAN
sharing parts of the manual - you have a SCSI SAN :-)

Subject:3584 Tape Sharing


We are running TSM 5.1.6.1 and have a 3584 connected via LVD SCSI (Adaptec
39160 controller) - no SAN.  We are looking at setting up another server
and
are exploring the Sharing possibilities.  We currently have  LTO1 drives
and
are also exploring upgrading/adding LTO2 drives.  I've searched this list,
Red Books and TSM doc and still have some questions.

One option is to partition the 3584 into 2 logical libraries and have a
SCSI
connection from each server to the 3584 to the first drive in the logical
partition.
This would allow us to put LTO1 drives in one partition and LTO2 drives in
the other, each being used by a different server.  Is anyone doing
something
similar - how do you handle tape protection between the two servers (if
same
type of tape in each partition)?

The other option is to use TSM Library Sharing and this is where I have
questions:

TSM Extended Edition has a feature called Library Sharing over LAN (for
libraries that support this function)
- Does the 3584 support this?  Any doc I see seems to say a SAN is
required?


With Library Sharing, can I have a mix of LTO1 and LTO2 drives
(partitioned
into two logical libraries becasue I am at 5.1) and share these 2 logical
libraries?

Thanks,

I did a dsmserv dbaudit fix=no deatails=yes

70 some millions records later it issued a series of messages

I brought the TSM server back online and followed the recommendations
on R. Simms site and did a query volhist type=STGREUSE

Found one, set it readonly, did a move data, and subsequent
reclamations went to completion.

A very  obscure senario.
