Did you recently switch your offsite pool from non-collocated to
collocated? Making that switch can cause this to happen.
During offsite reclamation for a collocated pool, the server checks the
clustering information for the objects on the volume being reclaimed.
Clustering information is typically based upon node name, and filespace.
If / when the volume was written in a non-collocated pool, all sorts of
nodes can get thrown onto that volume. During reclamation processing, the
server will only move one node's data at a time. Other objects will get
skipped and you'll see the ANR1173E message. Multiple passes are required
to fully clear the offsite volume.
Some things you can do:
-- Increase the batchsize value you're using. Set movebatchsize ###
I believe the default is 40, max is 1000
I believe the default is 40, max is 1000
-- Issue move data or move node data depending upon how many nodes are on
that volume and / or the nature of the storage pool.
that volume and / or the nature of the storage pool.
An additional step is to have a primary tape pool that the disk pool
migrates to. The logic for offsite volume reclamation is slightly
different when the copy resides in a tape (sequential) pool instead of on
disk. The server retries the reclamation (reprocesses the volume) more
when the copies are on tape.

Help with ANR1173E and disk storage pool
TSM server 5.2.3.1 on AIX 5.1 ML 5
On the weekend I got 1300 messages like the following:
09/11/04 10:02:17 ANR1173E Space reclamation for offsite volume(s) cannot
copy file in storage pool DISKDATA_SMALL: Node UNXV, Type Backup, File
space /, fsId 1, File name /DisasterRecoveryPlan/ 20040906.084014.
09/11/04 10:17:24 ANR1173E Space reclamation for offsite volume(s) cannot
copy file in storage pool DISKDATA_FC: Node UNXP, Type Backup, File space
/home/ncss_batch, fsId 5, File name /bin.prod/logs_ncss/log_backup/
frd001s.040806.20:22:39.rpt.
The problem is with two disk storage pools. Although I have several more
disk storage pools, only these two caused problems.
I searched the archives already, but all the help was for tape pools. What
do I do when it is a disk storage pool?
Thanks Miles
