2 Monitoring Disk Resources
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).
This chapter contains the following sections:
• HA Disk Monitor Reference
• Rules for Using the HA Disk Monitor with ServiceGuard
• Creating Disk Monitoring Requests
