Virtual Volumes Object Actions Menu

The following actions are available from the Actions menu option located on the Virtual Volumes object view Menu Bar:

Add Volumes

Adds a Virtual Volume range to CA Vtape. These are the actual tape volumes reserved in the tape management system for CA Vtape to use. A range can be from 100 volumes to 100,000 volumes. You will be prompted to provide the starting and ending volume serial numbers of the range.

Parameters are as follows:

Strt Vol Range

Beginning Virtual Volume of the range to be added. All 6 characters of the volume serial are required, and at least the final 2 characters should be 00 depending on the number of volumes to be added.

End Vol Range

Ending Virtual Volume of the range to be added. All 6 characters of the volume serial are required, and at least the final 2 characters should be 99 depending on the number of volumes to be added.

Delete Volumes

Deletes the specified range of Virtual Volumes from CA Vtape. The range can vary in size from 100 to 100,000 volumes. All of the Virtual Volumes in the range are validated to be in scratch status and portions of the range may not be deleted if not all volumes are scratched.

WP On VVP

Activates write protection for the Virtual Volume segment identified by the selected Virtual Volume. All 100 of the volumes associated with this segment will be write protected.

WP Off VVP

Inactivates write protection for the Virtual Volume segment identified by the selected Virtual Volume. All 100 of the volumes associated with this segment will have write protection removed.

Deq Virt Volume

Looks for any Group Write Requests (GRRs) matching the selected Virtual Volume and dequeues those GRRs.

WP On Virt Vol

Activates write protection for the selected Virtual Volume.

WP Off Virt Vol

Inactivates write protection for the selected Virtual Volume.

Start Recall

Initiates recall processing for the virtual volume selected. This should be differentiated from Recall VVO in that this process will cause the Virtual Volume to be recalled into cache even if a copy already exists.

Stop Recall

Stops recall processing for the selected Virtual Volume recall.
