Virtual TapeServer 6.04.04 for NonStop Servers Release Notes

Known Issues | 20
 Segfaults occur during shutdown and reboot. A performance monitoring agent may
segfault during shutdown. This causes no system impact. (TL-3320)
 Corrupt virtual tape causes server to become unresponsive. If the VTS server
loses power during a backup, causing the corrupt cartridge, the backup will fail. (It is
likely that the host running the backup will log a failure message.) As a result, VTS may
become unresponsive. (TL-3512)
WORKAROUND: Erase the resulting virtual tape and rerun the backup.
 Operations fail and errors are logged when log files exceed 2GB in size. When a
log file grows to over 2GB in size in less than a day, some commands will fail and errors
similar to the following are logged. (TL-3139)
ERROR: C06001 is locked by Filesize limit exceeded.
WORKAROUND: Remove the log file or wait until VTS rotates the file at 4AM.
 traceInit messages are logged to /var/log/messages. Messages similar to the
following are logged to /var/log/messages. These messages can be ignored. (TL-3151)
Jun 2 13:20:54 VTS06 slave: traceInit: Opening /proc/crds-trace
failed, No such file or directory
 Failures may occur if an autoloading pool contains an invalid cartridge. Only
valid cartridges should be added to pools within vaults. If other files are there,
inconsistent or unpredictable behavior may occur. (TL-3125)
WORKAROUND: Restart the Tapeserver service.
 Error message written to debug log if a physical tape drive is added that is
similar to an existing one. If an Ultrium physical tape drive is attached to VTS and one
is already in the database, an error message may appear in the debug log indicating that
it was unable to add this physical tape to the database. This message can be ignored. (TL-
2290)
 Interrupt requests are disabled while the server is idle. VTS may broadcast to all
terminals that it is disabling unused interrupt requests (IRQs). These warnings may be
safely ignored. (TL-1997)
 File size limit of 2TB can be overridden through the Pool Management page in
the UI. If you set the virtual tape limit above 2TB, VTS will not get an EOM before the
file system reaches the file limit and fails the I/O to VTS. (TL-2171)
WORKAROUND: Set the limit to 2TB, which is the maximum setting.
 Cartridge mounted too quickly after enabling tape server results in error code
102 and cartridge will not mount. After starting the TapeServer service on the
Supervisor Functions page, navigating to Virtual Media and mounting a cartridge fails
with an error of rc=102. (TL-1804)
WORKAROUND: Wait of 60 seconds or more to prevent error messages.
 Encryption allowed on cartridge exceeds cartridge limit. Encryption will cause the
size of the data to be larger than when it is unencrypted. 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.
