ARM Command

[Authorization: OPERATOR]

Note: All references to Sutmyn automated tape library products in this manual also refer to the automated library products produced by Memorex Telex.

Use the ARM command to control whether the Sutmyn LMS can remove drives from the eligible drive list (reduce the drive list) for a mount request.

You can improve tape mount automation and ARM performance by letting LMS restrict the eligible drive list to the drives that are best able to satisfy mount requests. When LMS reduction is active, CA VM:Tape submits the eligible drive list for a mount request to LMS. LMS applies site-specified LMS allocation control rules to determine which drives CA VM:Tape can and cannot allocate. LMS then reduces the eligible drive list by removing from it the drives CA VM:Tape cannot allocate.

You can make reduction active or inactive only if the LMS interface is defined and active.

The LMS allocation-control rules are supplied by the allocation domain table statements ALLOCATE, DEVICES, and DOMAIN. For more information, see LMS Systems Guide.

Note: CA VM:Tape checkpoints the reduction setting.
