Monitoring Disk Resources | HP HA s Software specification

Monitoring Disk Resources

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

•Hewlett-Packard High Availability Disk Array, Models 10, and 20

•Hewlett-Packard Disk Array with AutoRAID, Models 12 and 12H

•EMC Symmetrix arrays

•High Availability Storage System

•Single-spindle SCSI disks

HP-IB and HP-FL disks are not supported by the disk monitor. FiberChannel disks are not yet supported.

You should be familiar with how the physical and logical volumes are conﬁgured on all the nodes in your system and whether disks are conﬁgured with redundant PV links, mirroring, or both, or whether they are standalone disks. See HP-UX System Administration Tasks. For more information on conﬁguring disks in a high availability environment, see the technical whitepaper Choosing the Right Disk Technology in a High Availability Environment by Bob Sauers. Other information is available from the high availability web site at http://www.hp.com/go/ha.
