which VA generating syslog POWERFAILED messages

I have two VA7400's and one of them is generating the following messages to my syslog. How can I determine which VA is generating the message, please.

Re: which VA generating syslog POWERFAILED messages

Pat,

how do you know it is only one of the VAs?

You can decipher the device files:

the message says
device 0x1f195000 is PV3 in VG 7
so find the vg with a group file with minor number 7:
ll /dev/vg*/group | grep 0x070000

then see what is the third disk in that vg.
strings /etc/lvmtab | more

that device should match 0x1f195000

Anyway, for the VA and other disk arrays you should set the timeout value for LVM disks higher than the default, i.e. e.g. for LUN 5 run pvchange -t 180 /dev/dsk/c#t0d5
use this command for all VA disk devices.

Regards,
Bernhard
