ATL Performance

Using the Autopick facility or reserving drives when the LMS interface is configured could affect the performance of the ATL by increasing the time needed to perform mount and allocate requests.

• When the Autopick facility is configured with the LMS interface, CA VM:Tape selects the scratch tape to mount and then drives the mount to the tape’s location, even if the tape is outside the ATL.
• When you reserve a tape drive and the LMS interface is configured, CA VM:Tape moves the reserved drive to the beginning of the EDL, regardless of the drive’s proximity to the tape.

This section details how CA VM:Tape allocates tape drives for saved and scratch tape mount requests when using the LMS interface.

Note: For more information about how CA VM:Tape processes allocate and reserve requests, see Drive Allocation for Mount, Allocate, and Reserve Requests.
