Virtual TapeServer 8.2 Release Notes

Known Issues | 24
 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.
 Interrupt requests are disabled while the system is idle. VTS may broadcast to all
terminals that it is disabling unused interrupt requests (IRQs). These warnings may be
safely ignored. (TL-1997)
 Cartridge mounted too quickly after enabling TapeServer results in error code
102 and cartridge will not mount. After starting the TapeServer service on the
Manage System Tasks page, navigating to Virtual Tapes 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.
 Tape label not checked when writing to the tape. VTS does not check to ensure that
the label being written on the tape is the same as the name of the tape, thus allowing for
the possibility for a mislabeled tape. (TL-1051)
WORKAROUND: Delete the tape on the VTS host and recreate it with the correct label.
 Cartridges created in a batch show the same creation time in the event log.
(TL-996)
 Request to mount cartridge fails if a currently mounted cartridge is unmounted
by another process while processing the mount request. If a request is issued to
mount a cartridge in a virtual tape drive where another cartridge is mounted, the request
is ignored if the mounted cartridge is unmounted while VTS is processing the mount
request. (TL-368)
WORKAROUND: Attempt to mount the cartridge again.
 To disable ISC, two parameters must be set. The
ems_InterSystemCommunication_hosts and interSystemCommunication_enable
parameters must be set to indicate that ISC should be disabled. Otherwise, ISC will still
be enabled. (TL-240)
WORKAROUND: To disable ISC, set these parameters in the VTS configuration file:
interSystemCommunication_enable="NO"
ems_InterSystemCommunication_hosts=""
Then, stop ISC from the Manage System Tasks page.
