options supported in the Serviceguard and SGeRAC environment.The framework provided by the SGeRAC toolkit is unique in the high level of multi-vendor (Oracle, Symantec, HP) and multi-storage platform (CFS, SLVM, CVM, ASM over SLVM) integration it offers. SGeRAC toolkit uses the multi-node package and simple package dependency features integrated with HP Serviceguard and SGeRAC version A.11.
/dev/dsk/c3t15d0 would indicate SCSI controller instance 3, SCSI target 15, and SCSI LUN 0. HP-UX 11i v3 introduces a new nomenclature for device files, known as agile addressing (sometimes also called persistent LUN binding). Under the agile addressing convention, the hardware path name is no longer encoded in a storage device’s name; instead, each device file name reflects a unique instance number, for example /dev/[r]disk/disk3, that does not need to change when the hardware path does.
