For customers whose partitions function as a part of an RS/6000® SP complex
or an IBM ^ Cluster 1600, SysBack has specific boot and install utilities
to interact with PSSP. For these utilities, SysBack utilizes existing NIM resources
that are a default part of the SP or cluster configuration in order to provide a
server-initiated network boot and install through the control workstation. SysBack
also executes the required PSSP functions to bring the partition back into the SP
or cluster environment after system installation.
20.2.4 Multivolume backup and tape device support
SysBack interfaces with the tape drive units through generic SCSI commands
used by all drives. SysBack does not directly interface to a tape library robot or
auto-changer mechanism and, therefore, does not control its movement.
By design, SysBack simply ejects the tape when the end of volume is reached
and waits for the next volume to be loaded. For a stand-alone tape drive, human
intervention is required to load the next tape. However, if the unit is a tape
