Thanks Tab, I did exactly as you suggested, please verify it, and if possible clarify
some of my doubts
I created Sequential Access Storage Pools called RECLAIMDISKPOOL and said it's of
Device Class RECLAIMCLASS. RECLAIMCLASS is File Device Class type FILE with Max.
capacity of 2GB under /u13/adsmreclaim directory. The concern is, each time I start
reclamation, it create a huge files, as followings.
itb > pwd
/u13/adsmreclaim
itb > ls -alt | head
total 7596048
-rw------- 1 root dba 1791992909 Oct 01 10:12 00002263.BFS
-rw------- 1 root dba 2097152000 Sep 30 10:25 00002261.BFS
Are these files are temporary files, when does it gets refreshed? Are they actually
taking that much space? Do I need to do any cleanup?
Thanks,
Alyn

Subject: Re: Creating Reclaimation pool on disk
Alyn,
I'm using a similar technique. This is how I set up my system (ADSM 3.1.2 on
AIX 4.3.2).
** First in AIX:
Filesystem 1024-blocks Free %Used Iused %Iused Mounted on
/dev/seqlv1 17727488 17007016 5% 18 1% /seqfs1
** Then in ADSM define the device class (I used 235 MB volumes):
adsm> q devc tapedisk f=d
Device Class Name: TAPEDISK <=====
Device Access Strategy: Sequential
Storage Pool Count: 3
Device Type: FILE <======
Format:
Est/Max Capacity (MB): 235.0 <=====
Mount Limit: 15
Mount Wait (min):
Mount Retention (min):
Label Prefix:
Library:
Directory: /seqfs1 <=======
Server Name:
Retry Period:
Retry Interval:
Last Update by (administrator): TTREPAGN
Last Update Date/Time: 09/11/2000 12:01:19
** Then, in ADSM, define a storage pool to use the device class (I set
maxscratch to 63 which is 90% of the capacity - two other similar pools share
this disk resource):
adsm> q stg corptape f=d
Storage Pool Name: CORPTAPE <======
Storage Pool Type: Primary
Device Class Name: TAPEDISK <======
Estimated Capacity (MB): 0.0
Pct Util: 0.0
Pct Migr: 0.0
Pct Logical: 100.0
High Mig Pct: 25
Low Mig Pct: 0
Migration Delay: 0
Migration Continue: Yes
Migration Processes:
Next Storage Pool: CORPPOOL <=====
Reclaim Storage Pool:
Maximum Size Threshold: No Limit
Access: Read/Write
Description: Sequential disk pool for reclaiming data in
the L18
Overflow Location:
Cache Migrated Files?:
Collocate?: No
Reclamation Threshold: 100
Maximum Scratch Volumes Allowed: 63 <=======
Delay Period for Volume Reuse: 0 Day(s)
Migration in Progress?: No
Amount Migrated (MB): 173.32
Elapsed Migration Time (seconds): 25
Reclamation in Progress?: No
Volume Being Migrated/Reclaimed:
Last Update by (administrator): TTREPAGN
Last Update Date/Time: 08/07/2000 17:48:34
** Then in ADSM set the primary tape pool to use that pool as its reclamation
pool:
adsm> q stg corppool f=d
Storage Pool Name: CORPPOOL
Storage Pool Type: Primary
Device Class Name: 3575DEV
Estimated Capacity (MB): 1,807,864.9
Pct Util: 69.0
Pct Migr: 86.6
Pct Logical: 97.1
High Mig Pct: 90
Low Mig Pct: 80
Migration Delay: 0
Migration Continue: Yes
Migration Processes:
Next Storage Pool:
Reclaim Storage Pool: CORPTAPE <======
Maximum Size Threshold: No Limit
Access: Read/Write
Description: 3575 L18 Tape Storage Pool
Overflow Location:
Cache Migrated Files?:
Collocate?: No
Reclamation Threshold: 45
Maximum Scratch Volumes Allowed: 0
Delay Period for Volume Reuse: 0 Day(s)
Migration in Progress?: No
Amount Migrated (MB): 0.00
Elapsed Migration Time (seconds): 0
Reclamation in Progress?: No
Volume Being Migrated/Reclaimed:
Last Update by (administrator): TTREPAGN
Last Update Date/Time: 09/11/2000 13:00:34
Hope this helps.
Tab

Subject: Creating Reclaimation pool on disk
I am on 3.2.40, AIX, S70
I'm using 3570 for backup, and I need to create a pool on disk, my S70,
approximately 2GB
To be used for reclamation. I created a File Device Class and given the
directory name plus the size.
How I'm going to let assign this space to my Sequential Storage Pool
The option for Reclaim to storage pool is blank .
Thanks,
Alyn
