Hi.

If disk mirroring fails,
can we receive messages?

Hi,

I'm not 100% sure of your question, but
if your primary disk fails for any reason
and if disk mirroring is set up correctly
your system will continue to work. If
your disk does happen to fail there are
two areas where information is logged.
First there is /var/adm/syslog/syslog.log
dmesg and if you have it configured, the
EMS system will report errors into it's
own log file /var/opt/resmon/log/event.log

Hi,

you can setup a script that does periodically check the lvm for stale extents (cronjob) ie:

vgdisplay -v |grep -iq stale
if [ $? = 0 ]
then
vgdisplay -v |grep -i stale | mailx -s 'LVM stale event'
fi

Hi,

If you have EMS installed and the disk that fails is being monitored, root or the configured user will be sent an email and an entry is made in the /var/adm/syslog/syslog.log file. If you don't have EMS installed on the system, you won't come to know of a disk failure until you go and check the same using some tool like STM or even try a vgsync.

You can download EMS using this link, Cut and paste the link in your browser,

Hope this helps.
