The SAM-QFS 4.6 patch 04 contains a bug that can cause both import and export problems on direct attached tape libraries.
You may encounter the bug in one of the following ways:
- The "Mailbox Full" message is displayed on an export even when export slots are available
- An import fails when you enter the SAM-QFS import command
To confirm that you have encountered the bug, check the following:
- All device logging is turned on in the defaults.conf file for the library (devlog = all eq, where eq is the equipment ordinal for the library)
- Logging shows SAM-QFS sent a 37 (initialize element status with range) to a library and this command fails
The work around is to manually import/export tapes.
- # samd stop
- Open the library and manually insert/remove tapes.
- Close the library and let the library initialization complete.
- # samd start
The sam-catserverd will automatically discover the inserted/removed tapes and update the catalog accordingly.
This bug has been reported and was tracked under CR 6680812. A fix is available in SAM-QFS 4.6 patch 05.
