Virtual TapeServer 6.04.03.01 for NonStop Servers Release Notes

Known Issues | 13
 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 Supervisor Functions page.
 No activity or a “hung” command occurs when an import request is issued to a
physical drive that is unavailable. If a physical drive is unavailable (powered off,
cable disconnected, and so on), VTS does not properly handle the error and a timeout does
not occur, causing VTS to hang and require a reboot. (TL-61)
Web interface
This section has been subdivided to better classify the issues.
General
 Activity log on Import/Export page is not in chronological order. The log
messages seem to be listed in random order. (TL-4391)
 Editing a VTD without a license causes the VTD to be deleted. If the license is
removed and then you attempt to edit a VTD, the system deletes the VTD. (TL-3962)
 Debug message for an import job is displayed in the web interface. When
attempting to import a pool from physical tape, the following message is displayed:
is_cart_available: Cannot find vault: for cart:BIRDS2
However, the import is successful. This message is a debug message indicating that VTS
is checking if the cartridge that is being imported exists. This message is always the very
first line in the activity log that is displayed in the web interface for an import or export.
(TL-3948)
WORKAROUND: Click the CLEAR LOG button.
 Cannot cancel pending mounts. The web interface indicates “Cancelled 0 pending
mounts” but pending mounts are re-queued and given new reqnums every six seconds.
The clearmount process attempts to match the reqnum of the pending mount. If they
match, the pending mount is cancelled. If they do not match, the pending mount is not
cancelled, as indicated by this message in the interface and log: “Error: clearmount found
no match in mount queue for reqnum 000000663”. (TL-3304)
WORKAROUND: Cancel the pending mount within six seconds of the page or refresh the
web interface and then cancel.
