Common Unassigned Caps - Sun Microsystems storagetek sl500 Reference Manual

If Partition 1 requests a CAP import operation, the procedure is:
The operator selects Partition 1's CAP through either the local operator panel or
■
StreamLine Library Console.
The CAP button on the base module is pressed.
■
The top CAP door is opened. All remaining CAP doors remain closed.
■
The operator completes the operation.
■
If Partition 2 requests a CAP import operation, the procedure is:
The operator selects Partition 2's CAP through either the local operator panel or
■
StreamLine Library Console.
The CAP button on the base module is pressed.
■
The top CAP door remains closed. All remaining CAP doors open.
■
The operator completes the operation.
■
Multiple split CAP assignments are available within a library. This is in contrast to
common assigned CAPs (see below).
Note – As the default behavior, if no partition has selected a CAP through the
operator panel or StreamLine Library Console, the library will behave as if all split
configured CAPs have been assigned to the CAP button. When the button is
pressed, all CAP doors that are designated as split assigned will open to expose all
split configured CAP slots, provided that no common configured CAP slot
containing a cartridge is exposed.

Common Unassigned CAPs

The common (or unassigned) CAP configuration is present when there are no
specified CAP slots designated (split assigned) to a partition or partitions. Strictly
speaking, one does not "configure" or "assign" a CAP as common—any CAP slots
that are not split assigned are available for mutual use among the remaining,
unassigned partitions. Keep in mind that common CAPs are a single unit, shared
among those partitions that have no split assigned CAPs.
Common Unassigned CAPs—Example
Referring to
slots and drives in the base module for a single host. The remaining cartridge slots
and drives are a second partition used only by a second host. However, no CAP
slots are explicitly assigned for a partition—both partitions can use all CAP slots.
An example of an import operation sequence for a common CAP would be:
The operator selects the CAP through either the local operator panel or
■
StreamLine Library Console.
An operator presses the CAP button.
■
All CAP doors open.
■
A cartridge is placed in any CAP slot.
■
The CAP door is closed.
