Summary
Tapes are not mounted in a timely fashion. Successful tape mounts are inconsistent.
Symptoms
Jobs are failing because tapes are not mounted (a return code of 1121 is issued).
Resolution
If jobs are failing because tapes are not mounted and you have checked that there are no issues with connectivity, drivers, or the tape itself (for example, that it is not write protected), set the number of times that the software will try to mount the tape and the interval between retries. The settings are -r for the number of retries and -t for the time interval (in seconds). These parameters are set on the tape mount manager module SSTPTMM on the machine to which the problematic device is attached. Typical values are -r 8 -t 60 (retry 8 times at 60 second intervals):
- Windows: Use the registry editor and go to HKEY_LOCAL_MACHINE/Software/Syncsort/BackupExpress/<nodename>/0 and edit/create the SSTPTMM string value. Add -r x -t y where x and y are the values you want to use.
- UNIX: In the bin subdirectory of the DPX installation directory, edit the SSTPTMM script and add -r x -t y where x and y are the values you want to use.
- NetWare: In SYS:\ETC, edit SSTPTMM and add -r x -t y where x and y are the values you want to use.
You do not need to stop and restart the software. The change will go into effect the next time the software attempts to mount the device.
