Disk offline and online mount verification

[Lionel Liu]

Hello there,

We has two nodes cluster system, we sometimes get message from console say

DISK **** OFFLINE then online mount verification message like that.

One of disks happened twice, I wonder why it would happen make disk offline then starting online mount verification.

Regards

Lionel

Its possible a disk is exceeding its timeout due to heavy use.

You may wish to check the syslog on the individual machine for further detail:

/var/adm/syslog/syslog.log

You can increase the timeout and the messaging may stop.

This could however be an early indicator of some kind of trouble.

I recommend bringing up mstm,cstm or xstm and making sure the disks test out all right on the excercize function.
