Virtual TapeServer 8.4 Release Notes

Known Issues | 38
 Cartridge having less than minimum size is listed as erasable in Scan/Cleanup
after migration. If a cartridge is below the size specified by the cleanup_minimum_size_
MB parameter, the cartridge is scheduled to b
e erased by Scan/Cleanup after migration.
This is incorrect behavior; it should not be scheduled for erasure. (TL-0444)
Tape-to-tape export and import (native export and import)
 No warning is given if a job is scheduled without selecting a cartridge. No
warning is provided if a cartridge is not included when a job is scheduled. (TL-7934)
WORKAROUND: Select one
or more cartridges before the job is scheduled.
 A failed tape to tape import of encrypted cartridges is reported as successful.
When performing tape to tape imports of encrypted cartridges, the job status will
sometimes be reported as successful even though the job failed. The correct status can be
found in the job log. (TL-7896)
 Canceling an import leaves an empty virtual tape that can no longer be
mounted. Trying to load the tape displays “Failed to mount, unable to turn off
compression /VAULT02/6000L4/TT0116 “. (TL-6723)
WORKAROUND: Delet
e the virtual tape and then recreate it.
 Importing cartridges with similar names can be imported to the same virtual
tape. If a library has two cartridges with similar names (first 6 characters the same) and
they are selected for import, they can be imported to the same virtual tape. This is an
error condition that can be avoided by having uniqueness in the first six characters of the
cartridge. (TL-6530)
WORKAROUND: Ta
pe libraries attached to VTS should be configured to ignore the
media version. The media version is identified by the Ln at the end of a barcode (where n
= 1 for LTO1, 2 for LTO2 etc.).
 Tape-to-tape export does not detect supported block size or set block mode. A
tape-to-tape export writes a standard 256K variable block size. If the tape drive does not
support this, you cannot use the tape drive for tape-to-tape export (Virtual Tape Format).
(TL-6279)
 Incorrect failure information is recorded when tape-to-tape job fails. When a
tape-to-tape job runs and a non-SCSI failure causes the operation to fail, VTS incorrectly
records the failure as the last SCSI status that was received even if it was not that SCSI
operation that caused the failure. (TL-6651)
WORKAROUND: View th
e debug log to see the correct failure messages.
 Encryption option is displayed for a disconnected library with drives that do
not support encryption. If the library is disconnected, the encryption option may
appear as selectable; the library is not connected to allow VTS to verify the settings.
Selecting the option has no impact (because the drives do not support encryption). (TL-
6757)
 Editing a tape-to-tape export job allows encryption to be enabled for an
unencryptable drive. Running the job tries to enable encryption and fails. (TL-6862)
 Cannot create a tape-to-tape import job for a replicated virtual tape. You cannot
create a tape-to-tape import job for virtual tapes in a DATA0X partition. You can
currently export a replicated tape to a library or standalone drive but there is no way to
select it for import. (TL-6697)
