Virtual TapeServer 8.4 Release Notes

Troubleshooting | 50
General operations
 If a cartridge contains the maximum amount of data, encrypting the cartridge
will cause the cartridge limit to be exceeded. However, no error is given to indicate
this situation. The cartridge can be exported but if it is imported to a cartridge of the
original cartridge limit size, the import will fail. (TL-1168)
WORKAROUND: Import
the cartridge to a cartridge whose size is larger than the
original cartridge limit size.
 The portmap service is turned off by default. Due to a perceived security
vulnerability, the portmap service is turned off. This terminates the VTS's ability to
mount filesystems using NFS. (TL-6117, EAR-7149, EAR-7622)
WORKAROUND: In the ev
ent that NFS is needed in a test environment, start portmap:
service portmap start.
 Performance degrades when a disk fails because disk cache writes are disabled.
When a disk fails within a RAID set, the controller will automatically turn off disk cache
writes. This will decrease system performance because of this degraded condition. After
the failed disk is replaced and the RAID set is rebuilt, performance will return to normal
without need of intervention. Contact Support for field replacement instructions.
(TL-4513)
 Kernel call trace is displayed on console if cluster data is included in a
troubleshooting package. When generating a troubleshooting package, if the “Include
Cluster data” checkbox is selected, a kernel call trace will be displayed on the console.
This is normal behavior and does not affect system operations. (TL-5111)
 Rerun job in process if power is lost to system. If power is lost while an export is in-
progress, re-run the job to ensure that data is written to storage as expected. (TL-4607)
 BRMS may not update correctly if disconnected libraries are present in BRMS.
BRMS is not updated correctly if disconnected libraries exist. (TL-3953)
WORKAROUND: Remove ol
d non-responsive library devices and media from BRMS.
 GET FW STATE messages displayed on the console after restarting TapeServer.
Stopping and restarting TapeServer causes repeated messages similar to the following on
the console. (TL-3853)

 SCSI EJECT command on an empty VTD hangs the calling client's mt command.
When sending a SCSI EJECT command (mt -f /dev/st? eject) to an empty VTD, the
command will take up to a minute to timeout prior to returning. In releases before 6.04,
this command would return immediately. (TL-2317)
