Hello ADSM Experts,
I am running an IBM C62 optical library with ADSM Server (AIX 2.1/5.13).
The optical platters are rewritable and the capacity is 1.3GB on each side.
I defined several storage pools with 6 and 20 scratch volumes respectively.
Now all volumes of one of the storage pools are in use, but the migration value
in the query stg result is shown to be 50% !!
Storage Device Estimated %Util %Migr High Low Next
Pool Name Class Name Capacity Mig% Mig% Storage
(MB) Pool
----------- ---------- ---------- ----- ----- ---- ---- -----------
ODLPOOL2 ODL 99,661.8 45.1 50.0 90 70 TAPEPOOL2
ODLPOOL2 ODL 99,661.8 45.1 50.0 90 70 TAPEPOOL2
Also most of the platters are full, but adsm tries to allocate new scratch
volumes and refuses migration to the next storage pool.
I assume, that either adsm does not use both sides of the platters or something
is wrong with the volume count / or Format definition of the odl device-class.
So my question: is an optical disk
1.: one volume with 2600MB (as I assumed when defining the dev-class and
storage pools) or
2.: two volumes with 1300MB each?
If option 2 is correct, how can I update my definitions?
Now my definitions look like this:
Device-Class:
Device Device Storage Device Format Est/Max Mount
Class Access Pool Type Capacity Limit
Name Strategy Count (MB)
--------- ---------- ------- --------- ------ -------- -----
ODL Sequential 4 OPTICAL 2600MB 2,600.0 2
ODL Sequential 4 OPTICAL 2600MB 2,600.0 2
Storage pool:
Storage Pool Name: ODLPOOL2
Storage Pool Type: Primary
Device Class Name: ODL
Estimated Capacity (MB): 99,661.8
%Util: 45.1
%Migr: 50.0
High Mig%: 90
Low Mig%: 70
Migration Processes:
Next Storage Pool: TAPEPOOL2
Maximum Size Threshold: 50 M
Access: Read/Write
Description:
Cache Migrated Files?:
Collocate?: Yes
Reclamation Threshold: 60
Maximum Scratch Volumes Allowed: 20
...
Sorry for that much text.
Any hints are appreciated.
Best regards,
Karl Molter
