Several tapes with zero capacity and zero utilization
I'm new with the ADSM system, so I hope I don't sound to dumb here! I've been looking at the list for a couple of months and I've gotten a lot of good information from it so far. Here we go, I run a select command every few days to check on the number of reclaimable tapes we have in the system. When I get several tapes with a PCT_RECLAIM above 70-80% I run the reclamation process. We do the tape reclamation manually. Here is the select command we use: select volume_name,est_capacity_mb,pct_utilized,pct_reclaim from volumes where stgpool_name='COPYPOOL' order by pct_reclaim desc The following is part of the result I get: VOLUME_NAME EST_CAPACITY_MB PCT_UTILIZED PCT_RECLAIM SG0113 19317.595.9 4.1 SG0117 14658.097.1 2.8 SG0007 0.0 0.0 0.0---??

Re: Several tapes with zero capacity and zero utilization
I did the q vol status=pending and it has the same tapes. They are pending. I had forgotten that the tapes stay in the pending status for three days.

Re: Several tapes with zero capacity and zero utilization
That sounds like an excellent idea. At the moment we are running short on tapes until we get a new batch in. Do you know of an _easy_ way to tell just how many scratch tapes we have? We are using select statements using the info in the volumes table. The problem is the tapes only show in stgpool_name as either copypool or tapepool. I run a select statement to get the number of copypool tapes then another to get the number of tapepool tapes. Then I have to add then together and subtract that from the number of tapes we put in the library to begin with. It's a convoluted process but that's the best I can come up right now. I can't find a direct way to tell me the number of scratch tapes I have. -Original Message- From: Richard Sims [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 18, 2000 10:44 AM To: [EMAIL PROTECTED] Subject: Re: Several tapes with zero capacity and zero utilization When I get several tapes with a PCT_RECLAIM above 70-80% I run the reclamation process.

Re: Several tapes with zero capacity and zero utilization
For 3494's, you can use the mtilb command to count scratch tapes, or insert tapes - whatever class you want. I've got a shared library - 4 TSM servers, one 3494, and I run this script daily: echo "Scratch tapes on RTP1" /home/nickpc/data/scratchcount mtlib -l /dev/lmcp0 -qC -s012E | wc -l /home/nickpc/data/scratchcount echo "Scratch tapes on RTP2" /home/nickpc/data/scratchcount mtlib -l /dev/lmcp0 -qC -s013E | wc -l /home/nickpc/data/scratchcount echo "Scratch tapes on RTP3" /home/nickpc/data/scratchcount mtlib -l /dev/lmcp0 -qC -s014E | wc -l /home/nickpc/data/scratchcount echo "Scratch tapes on RTP4" /home/nickpc/data/scratchcount mtlib -l /dev/lmcp0 -qC -s015E | wc -l /home/nickpc/data/scratchcount echo "Number of insert tapes in UR13494" /home/nickpc/data/scratchcount mtlib -l /dev/lmcp0 -qC -sFF00 | wc -l /home/nickpc/data/scratchcount mtlib -l /dev/lmcp0 -qL | grep Intervention /home/nickpc/data/scratchcount more -e /home/nickpc/data/scratchcount I have a second script that runs this one and then mails the output file to me.

Re: Several tapes with zero capacity and zero utilization
I have a script that counts scratches- my 3494 is shared betweeen two tsm
instances, so I use
a table of category codes to sort out private/scratch for each tsm instance.
This, of course, is
from the library/category point of view, which may not necessarily balance 100%
to TSM's!
Here's the (ksh) script:
lookup_code()
{
table=/usr/tivoli/tsm/etc/category_table
desc=`grep ^$1 $table|awk -F= '{print $2}'`
}
echo
echo
echo "--- TSM carts ---"
echo
mtlib -l /dev/lmcp0 -qI|awk '{print $2}'|sort |uniq -c|while read count cat;do
lookup_code $cat
printf "%5d " $count
echo $desc
done
Here's the category table (tsmSF1 and tsmSD1 are my tsm instance names) :
0190=tsmSF1 private
0191=tsmSF1 scratch 3490
0192=tsmSF1 scratch 3590
01F4=tsmSD1 private
01F5=tsmSD1 scratch 3490
01F6=tsmSD1 scratch 3590
F00E=volume in error
FF10=eject pending
FF11=bulk eject
FF00=inserted. (unassigned, in ATL)
FFF7=pending
FFFA=manually ejected
FFFB=purge volume
FFFC=unexpected volume
FFFA=purge volume
FFFD=3590 cleaner
FFFE=3490 cleaner
=private volume
Cleaner carts don't seem to show in the normal mtlib -qI command, so you can
add the following to count these:
echo
echo "--- Cleaner Carts ---"
echo
mtlib -l /dev/lmcp0 -qC -s fffd|awk '{print $2}'|sort |uniq -c|while read count
cat;do
lookup_code $cat
printf "%5d " $count
echo $desc
done
But this still doesn't show us how many cleaning cycles are available on these
cleaning carts, so add the following to display that (plus the library empty
cell count):
echo
echo
echo "--- Library Status ---"
echo
mtlib -l /dev/lmcp0 -qL|egrep "available cells|3590 cleaner cycles"
echo
Sample output:
--- Cleaner Carts ---
4 3590 cleaner
--- TSM carts ---
106 tsmSF1 private
82 tsmSF1 scratch 3590
46 tsmSD1 private
263 tsmSD1 scratch 3590
50 inserted. (unassigned, in ATL)
--- Library Status ---
available cells311
avail 3590 cleaner cycles..374
Comments, corrections, and other code swaps welcomed!

Hi, I have the following alias in my .profile to provide scratch tape numbers.

Re: Several tapes with zero capacity and zero utilization
I have the following script defined in TSM. All I have to do, is: run q_n_scratch (or just click on the script I want to run, from the Web GUI) /* -*/ /* Script Name: Q_N_SCRATCH*/ /* Description: Display number of scratch */ /* for each libraries defined */ /* Parameter: none*/ /* Example: run q_n_scratch*/ /* -*/ select LIBRARY_NAME, count(*) as - "Number of Scratch" from libvolumes where - status='Scratch' group by LIBRARY_NAME Serge Gaudet, CMI Consultant "Tyree, David" To: [EMAIL PROTECTED] david.tyree@cc: SGMC.ORGSubject: Several tapes with zero capacity and zero Sent by: utilization "ADSM: Dist Stor Manager" [EMAIL PROTECTED] RIST.EDU 18/10/2000 10:09 AM Please respond to "ADSM: Dist Stor Manager" I'm new with the ADSM system, so I hope I don't sound to dumb here!
