The following applies to
NetBackup Enterprise Server only.
system (ACS) robots can have multiple library storage modules
(LSMs), each with multiple media access ports (MAPs). When you
configure a vault that uses an ACS robot, you can specify any MAP
or a subset of MAPs to use for media ejection. Vault ejects media
to as few of the configured MAPs as possible based on a nearest MAP
algorithm. The algorithm considers the volumes to be ejected, the
MAPs configured for ejecting in the vault, and the configuration of
the LSMs. The algorithm assumes that the LSMs are connected in a
line. If your LSMs are connected in a configuration other than a
line, see the following two sections within the NetBackup
See "Adjacent LSM
Specification for ACS Robots" in the NetBackup
See "Media Access Port
Default for ACS Robots" in the NetBackup
The Any MAP option does
not mean all MAPs; media are not ejected to all MAPs, media are
ejected to the nearest MAP in each LSM.
If you specify any MAP:
MAPs that have only one element are not used.
Vault selects from MAPs that are on-line when the
eject begins; MAPs that are off-line are not considered for eject
If only a subset of MAPs are used during ejection,
all MAPs are busy and unavailable. For example, if the media are
ejected to only two MAPs in one LSM, all MAPs are still busy.
For all other robot types
that have MAPs, media are ejected to the default MAP. NetBackup
does not support ejecting to multiple MAPs for other robot
