There are a number of situations in which the PVL won't allow the device/drive to be deleted:
• If the device/drive is still attempting to notify the Mover/PVR about being added
• If the device/drive is in the process of aborting Mover/PVR notification
• If the drive is in use by the PVL
• If the drive is not locked
• For disk: If storage resources haven't been deleted from the disk device/drive
• For disk: If the physical volume hasn't been exported from the disk device/drive
If it is only necessary to take a drive out of service for a finite period of time, the administrator should
follow the instructions in Section 7.1.1: Devices and Drives Window on page 202 to lock the drive and
prevent its use rather than permanently removing the drive as described in this section.
The Device and Drive configuration entry can be deleted using the Devices and Drives list window
(Section 7.1.1: Devices and Drives Window on page 202). Select the correct device/drive configuration
and click on the Delete button to delete the configuration. Once the drive configuration is deleted, HPSS
will no longer be able to use the drive’s resources.
7.2. Monitoring Devices and Drives
After the devices/drives are configured and are made available for service, the device/drive status may be
monitored via several SSM windows.
When a device/drive experiences a problem, the PVL and/or the Mover issues one or more alarms to
inform SSM users of the problem and to notify SSM of the changes in the device/drive state. SSM
reports the state change on the Device/Drives Status field on the HPSS Health and Status window. SSM
also reports the new state on the Devices and Drives list window, the Mover Device Information window,
and the PVL Drive Information window if they are being displayed at the time.
If an HPSS device or drive needs to be locked or unlocked or if any device/drive configuration needs to
be done, the Devices and Drives list window is the first stop (for detailed information, see Section 7.1.1:
Devices and Drives Window on page 202). It facilitates drive lock/unlock and also lets administrators
access the following windows:
• Disk/Tape Device Configuration - used to configure/modify/delete device and drive
configurations. See Section 7.1: Configure a New Device & Drive on page 196 for more
information.
• Mover Device Information - used to view or update the state of the Mover device. See Section
7.2.1: Mover Device Information Window for more information.
• PVL Drive Information - used to view or update the state or configuration of the PVL drive. See
Section 7.2.2: PVL Drive Information Window on page 214 for more information.
