Virtual TapeServer 6.04.03.01 for NonStop Servers Release Notes

Known Issues | 12
 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.
 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.
 Pool is restored to a cartridge resulting in data not being stored as expected. If
an exported pool is restored to a cartridge, the data will not be restored as separate
cartridges but will be stored as regular data on one cartridge. (TL-1041)
WORKAROUND: Restore pools to pools, not cartridges.
 Importing a pool into a different pool can create duplicate cartridges. When a
pool is imported, the cartridges are created. If the pool that is being used to import the
pool already has cartridges of the same name as the imported ones, duplication of
cartridges will result. This could cause other pools to disappear, cartridges to display
incorrectly or not appear. (TL-1039)
WORKAROUND: Review cartridges restored in this manner when there might be
conflicts with existing cartridges. You can rename the cartridges from the command line
(log in as the bill user) or delete duplicate cartridges.
 Cartridges created in a batch show the same creation time in the event log. (TL-
996)
 Virtual tape names must be unique. If virtual tape names are not unique, unexpected
results can occur in the VTS interface. For example, an error message might be displayed
after attempting to mount one of the tapes whose name is not unique. (TL-199, TL-219)
