IT12098: TIVOLI STORAGE MANAGER BA CLIENT IMAGE BACKUP ENTERS AN ENDLESS RETRY LOOP UPON A COPY STG POOL FAILURE

IBM Spectrum Protect client 7.1.4.x interim fix downloads

APAR status

• Closed as program error.

Error description

• The backup image is backed up to primary storage pool and copy
  storage pool simultaneously.  Tivoli Storage Manager BA client
  command Backup Image will retry in separate session if the
  orignial session fails if the copypool does not have enough
  space.
  
  Backing up to an active data storage pool can also run into
  the problem. If the active data pool is not vailable or
  there is not enough space, this can also cause image
  backup to show the same problem behavior.

Problem conclusion

• Upon the fix, the backup image will retry its data transaction
  in the same session so that the data can be stored in the
  primary storage pool if the original transaction has failed due
  to a copy pool write failure and COPYCONTINUE is set to 'yes'
  for the primary storage pool.
  

Temporary fix

• A fix for this problem is currently targeted for 7.1.4.1 interim
  fix package. Until this interim fix is actually available this
  information is subject to change at the discretion of IBM.
