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.

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
