Suspected the following APAR but it is address at 8.1.6 .

IT25199: ANR2033E DEFINE ASSOCIATION: COMMAND FAILED - LOCK CONFLICT.

Since we are issuing define stgpool rather than define association.
There is a possibility that we me be encountering a variation of IT25199.

Are there any other error message(s) around the time frame ANR2033e?

Was the Spectrum Protect Server recently upgraded to 8.1.8 ?

Would have to open a ticket with IBM to see if there is a work around or a APAR that may not be publish at this time.

Good Luck,
Sias

Hi Sias,

when running command define stgpool, admin console become stuck/hang. it need around 2-3 hrs then error ANR2033e appear. even to run command query stg it's becoma stuck too.
Spectrum was upgraded from 8.1.4 to 8.1.8 on August.

Yes, the ticket was opened for this case. below from support :

This is a define stgpool cmd... This holds the resources waiting by other threads

Waiter: (ssclass.c:1731 Thread 3226) Tsn=0:285660, Mode=isLock

Can you please :
1: don't run concurrent define stgpool the same time, this cmd acqire the same locks.
2: for now, please stop thread 339 and other define stgpool cmd

su - instance_id
db2 "force application (1230,8318,10407)"

After that finishes: cancel all the admin sessions... see if this can break the hang...

If that doesn't, schedule a time to halt restart.

After applying request from support, there is still error to run command define storagepool.
schedule a time to halt restart can not be applied since last halt process was stuck too.

when checking process db2 list utilities, there two process are executing :
1. TSMDB1.SD_REFCOUNT_UPDATES
2. TSMDB1.SD_CHUNK_LOCATIONS

thanks,
Zaka
