Figure 20-7 illustrates the relationships between systems or partitions using the NIM resource network boot method. Clients (stand-alone systems or partitions) network booting from one NIM master and installing from the NIM master or another system NIM Master AIX 5.3 Clients TCP/IP Network Boot/Install AIX 5.3 Boot/Install 5.3 SPOT 5.2 SPOT Tape Drives Disk File AIX 5.2 Figure 20-7 NIM resource network boot relationships 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 650 IBM Tivoli Storage Manager Implementation Guide
