Virtual TapeServer 8.2 Release Notes

Upgrade and Downgrade | 11
Upgrade and downgrade issues
 Links missing from System Updates page after downgrade. After downgrading,
links may be missing on the System Updates page.(TL-7611)
WORKAROUND: Log out, shut down the browser, and then relaunch a browser and log
in again.
 Reverting to a previous version may revert the system to an unexpected
version. The upgrade process determines the version to revert to by checking the
timestamps of all system backup images in the /home/bill directory and reverting to the
last (newest) backup image in that directory. If the timestamps have changed on the
backup images due to touching or moving the images, the wrong image may be used to
revert. (TL-6152, EAR 7329)
WORKAROUND: If the system backup image timestamps have changed as a result of
touching or moving the images, identify the image that needs to be used by looking at the
timestamps in the filename. Then, issue the touch sysbackup-image_name.tbz
command from the command line before clicking the revert link in the web interface. This
will cause the proper backup file to be used when reverting to a previous version.
 The sysbackup file listed in the upgrade log is not always correct. The variable
that is used to hold the sysbackup filename during upgrade processing is sometimes
incorrectly overwritten, which results in the wrong sysbackup name being listed in the
upgrade log. This is a logging issue only and does not affect functionality. (TL-6150)
 Version updated though upgrade fails. If an upgrade fails, the system may display
the incorrect version. This is misleading. (TL-6180, EAR 7386)
WORKAROUND: Confirm the upgrade is successful by reviewing the upgrade-
YYYYMMDD-HHMMSS.log log.
 VTD fails after upgrade if SCSI port is switched to Physical mode while virtual
device is still functioning. Previously, a SCSI port could be switched back to “Physical”
mode while still allowing a “Virtual” device defined on it to function properly. This is no
longer supported, and any port that has a “Virtual” device on it must be in “Virtual” mode.
(TL-5207)
 Update process does not roll back changes after a failure. If there is a failure
during the installation of a patch or IR, an error is returned but the web interface does not
change the version information of the software. The system is left in an unusable state.
(TL-4108)
WORKAROUND: Stop all processes from the Manage System Tasks page and attempt
the upgrade again.
