Setting Up the Hardware Event Monitor
(HP-UX Only)
Hardware event monitors run on HP-UX hosts, versions 10.20 and later. The Disk
Monitor (disk_em) monitors all disks bound to sdisk drivers. Consequently, if the
Disk Monitor is active on your host, it is already set up to monitor the disks of a new
disk system. If you need to install or activate the Disk Monitor, refer to the
EMS
Hardware Monitors User’s Guide
in the latest IPR Support Media or on the Web
(
http://www.docs.hp.com/hpux/diag/
).
The way you configure the monitor determines, among other things, where event
messages will be sent and what level of severity will be reported.
Configuration Overview
The following steps will help you identify and resolve disk system failures:
1
Gather information from all sources:
– Hardware event notifications (page 25)
– Disk system LED status (page 25)
– Online information tools (page 26)
2
Isolate the cause of the problem (Table 7 on page 30).
3
Correct the problem. (See page 19 for disk module removal and replacement.)
4
Verify operational status with
ioscan
or other host utilities.
Note
This Disk Monitor should not be confused with the EMS disk
monitor that is used to monitor LVM resources.
