Hello Tina,
I did specify the maxpr parameter....here's the relevant bits from the q stg
commands etc...
backup command: backup stg ssa_pool copy_pool1 maxpr=2
q stg ssa_pool f=d..
Storage Pool Name: SSA_POOL
Storage Pool Type: Primary
Device Class Name: DISK
Estimated Capacity (MB): 138,240.0
Pct Util: 39.1
Pct Migr: 39.1
Pct Logical: 100.0
High Mig Pct: 100
Low Mig Pct: 90
Migration Processes: 2
Next Storage Pool: 3590_POOL1
Collocate?:
q stg copy_pool1 f=d..
Storage Pool Name: COPY_POOL1
Storage Pool Type: Copy
Device Class Name: 3590_DEVC
q devc 3590_devc f=d ....
Device Class Name: 3590_DEVC
Device Access Strategy: Sequential
Storage Pool Count: 4
Device Type: 3590
Format: 3590C
Est/Max Capacity (MB): 0.0
Mount Limit: DRIVES
Mount Wait (min): 60
Mount Retention (min): 60
Label Prefix: ADSM
Library: 3494_LIB1
adsm> q drive
Library Name Drive Name Device Type Device ON LINE
------------ ------------ ----------- ----------------
-------------------
-------------------
3494_LIB1 3590_DRV1 3590 /dev/rmt0 Yes
3494_LIB1 3590_DRV1 3590 /dev/rmt0 Yes
3494_LIB1 3590_DRV2 3590 /dev/rmt1 Yes
I am at a loss...I now understand why migration uses only 1 process (thanks
Dwight !).
But I don't understand why the "backup stg" with "maxpr=2" only uses one
process...
frustration reigns
Andrew.
