Disable automatic processes like inventory expiration,
migration, reclamation, and identification of duplicate data and set
up schedules so that you can control when these operations are completed
during the daily schedule.
About this task
Review the following sections for examples of disabling automatic
operations and setting up schedules. Some general setup steps are
omitted and the example uses a particular order for the server processes.
However, you can reorder the processes to better fit your environment.
Procedure
- Disable automatic inventory expiration by setting the EXPINTERVAL server
option to zero.
setopt expinterval 0
- Disable automatic migration and reclamation processes by
using the DEFINE STGPOOL command to set the HIGHMIG and RECLAIM parameters
to a value of 100. You might have to
increase the number of allowed processes for migration and reclamation
in order for them to complete in a reasonable amount of time. The
actual number of processes depends on available tape drives. If you
have already defined storage pools, you can change values for the MIGPROCESS and RECLAIMPROCESS parameters
by using the UPDATE STGPOOL command.
def devc LARGEFILE devt=file mountlimit=500 maxcap=20480m dir=/tsmfile
def stg FILEPOOL LARGEFILE maxscratch=200 reclaim=100 hi=100 lo=0 migpr=4
reclaimpr=20 next=tapepool
- If you have storage pools that are defined with deduplication
enabled, disable the duplicate identification processes:
def stg FILEPOOL LARGEFILE maxscratch=200 reclaim=100 hi=100 lo=0 dedup=yes
identifypr=0 migpr=4 reclaimpr=4
