Re: lvol has ??? in lvdisplay -v
Check with an ioscan if you can see the disk; it is possible that you lost one disk if you see a NO_HW the disk has gone bad. If thisis the case you will need to break the mirror and replace the disk and then set the mirror again on the new disk.

SolutionShalom,
/dev/dsk/c1t8d0 is most likely dead.
dmesg
ioscan -fnCdisk
ioscan -fnNCdisk # 11.31 legacy i/o disabled.
ioscan -m dsf
Lets get a full picture.
From What I see you have lost a mirror but still have the whole file system.
Mirroring worked.

Re: lvol has ??? in lvdisplay -v
Hi ,
Check for /var/adm/syslog/syslog.log & see in case you see any lbolt errors in this log file .
If you find any lbolt error , then match it with details in /dev/rdsk/

Re: lvol has ??? in lvdisplay -v
Shalom,
The EMS message is merely confirmation of what you already know. A disk died.
when disk is safely replaced EMS will stop squawking about this.

Re: lvol has ??? in lvdisplay -v
yes ioscan -m dsf will not work on 11.11
Having no indicator of your OS, I had to use my procedure which I scraped off an 11.31 support document.
The basics are still workable as in the other ioscan commands.
