Looks to me that you might have a hardware issue here.

If you do a "diskinfo" on the disks, do you get sensible information?

Michael Tully — Tue, 02 Mar 2004 03:16:15 GMT

Your problem is that you can't activate a volume group with less than 50% of the LUN's available, this is called 'quorum'. Seems to me you have a problem with a connection, from what I've seen here to a clariion disk array. (assuming it is a clariion) Is there a connectivity problem from the management station. Perhaps a service processor port? Are there other volumes that have similar messages?

Hi,

Could it be that the disks have bad blocks.
try a diskinfo -v /dev/rdsk/c?t?d?
And dd if=/dev/dsk/c?t?d? of=/dev/null bs=4096k

If not you can mv /etc/lvmtab /etc/lvmtab.org and # vgscan -v -p -a | more
if ok vgscan -v -a
If not you can try vgcfgrestore to the disks, before activating.

HTH,

Gideon

Try doing a dd for both of the disks to see if there are some bad blocks,

dd if=/dev/dsk/cxtxdx of=/dev/zero bs=1024k

You should see equal number of blocks in and out without any error.

May be I am asking some silly stuff ... but I guess might have tried with the wrong device file ...

diskinfo:can't open /dev/rdisk/c2t1d3
-------

try with /dev/rdsk/c2t1d3

Just checking, did you spell it correctly:

diskinfo /dev/rdsk/c2t1d3
diskinfo /dev/rdsk/c1t0d3

Perhaps you can tell us more about your system?
When was it last rebooted?
When was it last used successfully?
Have any changes been made recently?

Re: activate vg

zhj_1 — Tue, 02 Mar 2004 03:55:25 GMT

diskinfo -v /dev/rdisk/c2t1d3
diskinfo: can't open /dev/rdisk/c2t1d3:NO such file or directory

dd if=/dev/dsk/c1t0d3/ of=/dev/null bs=4096k

dd read error:I/O error

----

Since you got the error for other disk too, do a diskinfo again,

diskinfo -v /dev/dsk/c1t0d3

Is it a internal or external disk?? Mostly I think the disk has some bad blocks. Do you have spare disks and backup???

Hi,

You could try an insf -e .Since you got a no such file or dir on the diskinfo command.
