Virtual TapeServer 6.04.03.02 for NonStop Servers Release Notes

Resolved Issues and Enhancements | 7
 vtsa user could not issue mount command. From the command line, the vtsa user
could not issue the /bin/mount command. This has been fixed. (TL-3981)
 SCSI commands timed out for MODE_SELECT, TUR, and WRITE_FILEMARKS.
VTS flushed its cache causing delayed responses to the SCSI commands sent by the host
server. The amount of memory used for disk write caching has now been tuned and this
problem no longer occurs. (TL-4207, EAR 6223)
 Physical devices now automatically created when connected. A new device type is
now listed on the Manage Connections page when physical device is connected to VTS.
“auto-” precedes the name of new device emulation to indicate that it was automatically
created when the new physical device was attached. (TL-3797)
 Check condition now returned for non-existent or unsupported pages. A mode
sense command for a page that does not exist or is not supported by the device emulation
now returns a check condition. Previously, VTS was returning all pages supported,
causing the host to be confused and interpret the emulation as something other than the
device type. (TL-3820, TL-3657)
 SCSI performance was 80MB/sec rather than 160MB/sec. Previously, the initiator
was not performing SCSI parallel protocol request (PPR) negotiations as required for
U160+ speeds. This was because the INQUIRY response from VTDs was not setting the
SPI3 bit to allow double-transition (DT) and single transition (ST) clocking. These bits are
necessary to support U160+ speeds. This has been fixed. (TL-4105)
 Error logged to /var/log/httpd/error_log when a cartridge was mounted. When
mounting a cartridge, an error similar to the following was logged in /var/log/httpd/
error_log:
vtmeta: Error /VAULT00/POOL1/CART1: Unable to lock file.
This was a logging issue only and no longer occurs. (TL-2453)
Web interface
This section has been subdivided to better classify the issues.
General
 Could not edit EMS hosts or virtual devices. If more than one EMS host or virtual
device was created, you could not edit any of them other than the first in the lists. This
has been fixed. (TL-3714)
 Logwatch Parent Directory link displayed nested pages. Selecting from the
Supervisor Functions -> Examine Logwatch Output -> Parent Directory link caused the
page to be displayed within the same page. This has been fixed. (TL-3728)
Manage Connections
 Fields on Edit Virtual Tape page were too small. When editing a virtual tape, the
fields for tape_type and host_type were too small and you could not see what was selected.
The fields have now been resized. (TL-4085, EAR 6135)
 Could not modify the bus number assigned to a VTD. Because of the - (dash) in the
drive's serial number, you could not alter the bus number for the VTD. Any alteration to
the drive's serial number caused any backup application to see the drives as new
hardware. This has been fixed. (TL-3379)
