Virtual TapeServer 8.4 Release Notes

Known Issues | 29
 PTLI reservation is unclear and may cause error. If you change a port from physical
to virtual mode, an error is displayed if you attempt to create a virtual device on the port
where that physical drive was connected. The reservation of the PTLI is a feature, but the
reason for it may not be clear and the method to clear it up is not indicated by the error
message. (TL-5946)
WORKAROUND: Delet
e the PTLI using the Advanced link on the Manage Virtual
Devices page.
 Cannot modify target ID of Fibre Channel VTD on Manage Virtual Devices page.
You cannot modify a Fibre Channel VTD's target ID. (TL-5975)
WORKAROUND: Delet
e the VTD and re-add it with new target ID.
 Incorrect error message displayed when attempting to create a VTL on a bus
that has more drives than LUNs. When attempting to create a VTL on a bus that has
more drives than LUNs, the error message is incorrect. It states, for example, “Unable to
create VTL with the specified number of drives as bus 4 lun 8 combination is already in
use”. The indicated LUN does not exist and, therefore, cannot be in use. (TL-4466)
 VTL creation may only be done as the first device on a port starting with LUN 0.
If a device already occupies LUN 0 on a port, VTL creation will fail indicating there is
another VTL present even if the device already occupying LUN 0 is a virtual tape drive
and not a VTL. (TL-5948)
 Manage Virtual Devices page does not select available values when creating
VTDs. If you attempt to create a VTD after other VTDs have been created, the Manage
Virtual Devices page does not automatically select available values for the LUN and
target. If you do not change the values, the creation will fail. (TL-3491)
WORKAROUND: Modi
fy the LUNs to unused LUNs, modify the target, and then save.
Then, change the LUNs back to the original LUNs.
 Cannot create a VTL if LUNs 0, 1, and 2 are not free. If you try to create a VTL, it
will fail and indicate that there can only be one VTL per bus, though no other VTLs are
defined. LUN 0, 1, and 2 must be free. (TL-4063)
 Cannot delete VTD in VTL. If you edit a VTL and reduce the drive count to remove a
VTD that is included in a VTL, an “Insufficient number of VTD licenses” message may be
displayed if you are at the maximum number of VTDs for your license and you cannot
delete the VTD. (TL-3982)
System Settings
 The System Settings page may fail to load. Failing hardware attached to VTS may
cause the Systems Settings page to fail to respond. (TL-7160)
WORKAROUND: Disconnect the failing
hardware from VTS.
 Settings for disconnected tape drives and libraries can be edited. Although a tape
drive or library may be shown as “disconnected” on the Manage Settings page, the
physical drive settings can be edited. Changes made to the device settings are saved
independent of the device's state. (TL-6388)
 Edit System Settings page can timeout if the drives are busy or being used by
scheduled jobs. (TL-6376)
WORKAROUND: Wai
t until the jobs are completed and drives are not in use to view or
modify drive information.
