Virtual TapeServer 8.4 Release Notes

Troubleshooting | 53
Data Encryption (SecureVTS)
 Tape library must be configured for encryption to support export of encrypted
tapes. The external tape library must be correctly configured to allow VTS to manage
encryption. Refer to the library documentation for instructions. (TL-6435)
 When encrypting or decrypting a cartridge and TapeServer stops, temporary
directory and file are not deleted. Do not stop TapeServer or restart VTS unless the
system is quiesced. (TL-3071)
 Decrypting a large cartridge with an invalid key takes a long time to fail. If the
key is invalid or if an incorrect path to the key was given, VTS may take up to 10 minutes
before failing to decrypt a large cartridge. There are no warning messages indicating that
decrypting could take a while for large files. (TL-3052)
Tape-to-Tape export
 Virtual tapes must be exported to a physical tape library that has physical
cartridges with matching barcodes. If a matching cartridge is not found during a
tape-to-tape export to a library, the job.log will state “Transfer of <CARTNAME> failed;
dup command returned 247”. (TL-5845)
 Tape-to-Tape export fails when library is moved to a different port. All devices
that are not attached when TapeServer starts must be manually discovered using rescan-
scsi-bus.sh. (TL-5698)
 Bus, target, LUN, and device number replaced by friendly name for tape-to-tape
exports. In prior releases, when performing a tape-to-tape export job, the drives
presented included Bus, Target, LUN, and /dev/nst# as well as the make and model. With
the addition of the friendly names to the web interface in 6.04.05, all of this information
has been replaced with the friendly name as it's configured in the Physical Drives section
of the Manage Settings page. (TL-5844, TL-5155)
 Cartridge remains locked after failed tape-to-tape export from Manage Virtual
Tapes page. Tape-to-Tape export performed from the Manage Virtual Tapes page on a
cartridge in a pool (not in a VTL) fails and the cartridge is not unlocked after the failure.
If the export is done from the Configure Tapes and Pools page, the cartridge is unlocked
after the failure. (TL-4536)
Migration and stacked export
 Export relies on the capabilities of the backup management agent. The agent will
retry the backup repeatedly until it determines file change has not occurred. This could
mean that an empty virtual tape is backed up if a virtual tape is erased after the stacked
export has begun but before it has completed. (TL-4922)
 The 64-bit Networker 7.4 client cannot connect to the Windows 2003 64-bit
server. Networker 7.4 client running on VTS cannot be seen by Windows 2003 Server.
(TL-1836)
WORKAROUND: Instal
l the 32-bit client.
