Virtual TapeServer 6.04.03 for NonStop Servers Release Notes

Known Issues | 26
 Mounts fails when ems_virtdevs and ems_hostdevs entries are delimited by
commas. In vts.conf, the entries for the ems_virtdevs_<HOST> and
ems_hostdevs_<HOST> must be separated by a space. Using a comma delimiter does not
work. (TL-2292)
 If a mount command is sent to a non-existent virtual tape drive, VTS reports
that the tape is missing, not the drive. When a mount request is received by EMS, if
the request specifies a tape drive that is not configured on the VTS, VTS sends a
notification to the host that the tape is not found. It should send a notification that the
drive is not found. (TL-2293)
 VTDs intermittently stop on NonStop if tapeserver is restarted repetitively. If
tapeserver is restarted several times in a row, the connection could be lost from the VTS
to host. (TL-1844)
WORKAROUND: Stop, reset, and restart the tape drive(s) from the host.
 Device names beginning with $ result in ems_hostdevs and ems_virtdevs are not
logged. If VTS is used with an HP NonStop host and the device names begin with $, the
ems_hostdevs and ems_virtdevs values are blank in the log. This can cause confusion if
reviewing the logs. (TL-1562, EAR 4030)
AutoCopy and Instant DR
 AutoCopy (replication) is supported for virtual tape devices within a VTL only.
A standalone VTD cannot perform replication. This is not explicitly documented. (TL-
4026)
 Copy not initiated if cartridge modification times differ by less than six seconds.
When a cartridge is mounted, its modification time is recorded. When it is unmounted, the
modification time is compared to the modification time when mounted and, if they are
different by six seconds or more and if AutoCopy is configured, the copy is initiated. Also,
when a cartridge is mounted, any running AutoCopy operation is terminated because the
cartridge data may change.
As a result, if a cartridge being copied is mounted and then unmounted without the
modification time changing by more than six seconds, the cartridge is not copied. In this
case, the mount cancels the original copy and when the unmount takes place, the system
does not see that a copy is needed. (TL-4001)
 Aborted error message listed in debug log when Instant DR job is dispatched.
When an Instant DR job is dispatched, the debug log displays this message, though
Instant DR function properly. (TL-3940)
Tue Dec 01 13:39:06 2009: IDR Backup Set "/usr/local/tape/etc/IDR/
IDR_JOB1.syncjob" already running; execution aborted!
 Autocopy locks the source cartridge but not the target. The user should be able to
configure cartridge locking, with the default being that remote cartridges are locked. (TL-
2529)
 AutoCopy may create pools on a server that could not otherwise be created.
AutoCopy may be used to create pools on a VTS server that could not otherwise be
created, such as having both a 'TEST' and a 'test' pool. (TL-868)
WORKAROUND: When using AutoCopy, you may need to review of all AutoCopy pools
to ensure that there are no duplicate pool names and correct for any such occurrences.
