sbtsmlist -r fails ANS1245E (RC122)
Backups fail BMR0041E backup already in progress. When trying to remove the backup with:
ANS1245E (RC122) The file has an unknown format
TSM Client API return code 122 is: 0122 E: DSM_RC_UNKNOWN_FORMAT The file has an unknown format.
A common cause is TSM Client API version is downlevel from the API version used to start the backup.
Resolving the problem
Upgrade TSM Client and API to a later version.
For example, in one case customer had upgraded sysback from 6.1.2 to 6.1.3 and TSM API from 18.104.22.168 to 22.214.171.124. They were able to successfully remove the backup to TSM by upgrading TSM client to 6.2.4.
TSM client is available at the FTP site here:
