Managing the HP SureStore E Disk Array 12H on MPE Configuring AutoRAID SCSI LUNs for MPE/iX Configuring AutoRAID SCSI LUNs for MPE/iX This section will explain how to configure the AutoRAID using the MPE/iX SYSGEN along with a list of configuration requirements. Configuration Requirements There are two configuration requirements MPE/iX has that the user should be aware of before starting the SYSGEN configuration: • SCSI LUN 0 on the AutoRAID should be configured first. LUN 0 will be used by the ARM utility for communications with the AutoRAID. • SCSI LUN 0 should have the lowest LDEV number configured compared to the LDEVs assigned to SCSI LUN-1 through 7. For example: LDEV 30 LDEV 32 LDEV 33 LDEV 35 LDEV 37 LDEV 38 LDEV 39 SCSI LUN 0 SCSI LUN 1 SCSI LUN 3 SCSI LUN 4 SCSI LUN 5 SCSI LUN 6 SCSI LUN 7 NOTE! The LDEV assignment does not have to be contiguous, but only the lowest LDEV should be assigned to the lowest number SCSI LUN. Configuration to a non-existent SCSI LUN is not recommended. MPE 121
