This chapter recommends ways to configure requests to the HA Disk Monitor for most high-availability configurations.

You can monitor the following SE (single-ended) or F/W (fast/wide) SCSI disks:

Hewlett-Packard High Availability Disk Array, for both Fast/Wide SCSI and Fibre Channel
Hewlett-Packard Disk Array with AutoRAID, Models 12 and 12H
Hewlett-Packard SureStore E Disk Array XP256 for both Fast/Wide SCSI and Fibre Channel
Hewlett-Packard High Availability Storage System
EMC Symmetrix arrays for both Fast/Wide SCSI and Fibre Channel
Single-spindle SCSI disks

HP-IB and HP-FL disks are not supported by the HA Disk Monitor.

You should be familiar with how the physical and logical volumes are configured on all the nodes in your system. You should know whether disks are configured with redundant PV links, mirroring, or both. You should also know if they are standalone disks. See Managing Systems and Workgroups (HP Part Number B2355-90664).
