Disk Failure Notification Messages from Diagnostics

If you have Event Monitoring Service (EMS) hardware monitors installed on your system, and you

enabled the disk monitor disk_em, a failing disk can trigger an event to the (EMS). Depending on

how you configured EMS, you might get an email message, information in

/var/adm/syslog/syslog.log, or messages in another log file. EMS error messages identify a

hardware problem, what caused it, and what must be done to correct it. The following example is

part of an error message:

Event Time..........: Tue Oct 26 14:06:00 2004

Severity............: CRITICAL

Monitor.............: disk_em

Event #.............: 18

System..............: myhost

Summary:

Disk at hardware path 0/2/1/0.2.0 : Drive is not responding.

Description of Error:

The hardware did not respond to the request by the driver. The I/O

request was not completed.

Probable Cause / Recommended Action:

The I/O request that the monitor made to this device failed because

the device timed-out. Check cables, power supply, ensure the drive

is powered ON, and if needed contact your HP support representative

to check the drive.

For more information on EMS, see the diagnostics section on the docs.hp.com website.

LVM Command Errors

Sometimes LVM commands, such as vgdisplay, return an error suggesting that a disk has problems.

For example:

# vgdisplay –v | more

…

--- Physical volumes ---

PV Name /dev/dsk/c0t3d0

PV Status unavailable

Total PE 1023

Free PE 173

…

The physical volume status of unavailable indicates that LVM is having problems with the disk. You

can get the same status information from pvdisplay.

The next two examples are warnings from vgdisplay and vgchange indicating that LVM has no

contact with a disk:

1 2 ... 5 6 7 8 9 10 11 12 13 14 15 ... 66 67
