Locking a disk drive has little effect since disks are logically mounted when the PVL initializes and are
not usually unmounted; however, a disk drive must be in the locked state to be deleted.
7.4.3. Repairing the State of a Device or Drive
A drive can enter an error or suspect state as reported by the PVL, Mover, or both. After a drive has
entered one of these abnormal states, it can be repaired to return it to a normal state.
From the Devices and Drives window (Section 7.1.1 on page 202), select the desired device/drive entries
and then click on the Mark Repaired button appropriate for that device/drive type. Another way to
change a device/drive state to "repaired" is to bring up the PVL Drive Information window or the Mover
Device Information window and changing the Administrative State to Mark Repaired.
Repairing the state of a device/drive is only an instruction to the server to reset the displayed device/drive
state value. It does not correct any underlying problems that might still exist. Rather, it is a means by
which the administrator can notify the server that the underlying problem has been addressed outside of
the server. It is used for problems that the server cannot fix by itself such as a drive being offline or a
tape getting stuck in a drive.
7.4.4. Resetting Drive Statistics
Both the PVL and Mover maintain statistics related to a drive. The PVL maintains an error count as well
as a count of the number of times a cartridge is mounted. The Mover maintains the count of the number
of errors encountered and the number of bytes read and written on the drive. These values can all be reset
to zero by the Reset button located next to the statistic field on the appropriate window.
