CAP Modes
Auto Enter Mode
Only HLI libraries support CAP auto enter mode (see the tape management software
documentation).
CAP auto enter mode enables a library operator to open a CAP and initiate an enter
operation without issuing an explicit enter request. CAPs in auto enter mode are left
unlocked and do not require a host reservation. In a partitioned library, CAPs must be
dedicated to use auto enter mode.
Manual Mode
Manual mode is the most secure CAP mode. When in manual mode, the system locks
a CAP by default. To initiate an enter or eject operation using manual mode, enter an
explicit enter or eject request before pressing the
CAP Open
button.
Assignment Mode
Only non-partitioned FC-SCSI host connections support assignment mode. The CAP
assignment mode controls whether CAPs can be used for normal host operations or
for diagnostic operations (see
"Changing the CAP Assignment Mode in a
Non-Partitioned FC-SCSI Library"
CAP Usage Order when Ejecting Cartridges with FC-SCSI Hosts
In a non-partitioned library, the SCSI interface treats all CAPs as one. When you
initiate an eject operation from an FC-SCSI host, the robot loads cartridges into the
left-most rotational CAP, then moves right, and then moves to AEMs. For partitioned
libraries, the CAP priority depends on how CAPs are allocated to partitions.
For the following example, assume an FC-SCSI library with a base module, two CEMs
(one on each side of the base), and two AEMs (one on each end of the library). For an
eject operation of 350 cartridges, the robots fills CAP slots in the following order:
