Amit, In addition, if you are running a single JES2 in your SYSPLEX you can display other LPARS in the SDSF "DA" display using the "SYSNAME sysid" line command.
Alternatively you can use the ISPF Table based RMF II display to monitor the other LPARS in your SYSPLEX by simply overtyping the System ID in the upper right hand corner with the one you want. Depending on your installation you can typically get to this (far superior) version of RMF II with the command ERBRMF, or TSO ERBRMF, and then follow the menus. This is feature is enabled by XCF and does not require a parallel SYSPLEX, but you do need a MAS for the DA SYSNAME to work. I regularly use the RMF II feature in a four system GRS ring.
