Can you read those disks at all?

What's the output of:

diskinfo /dev/rdisk/disk229
diskinfo /dev/rdisk/disk230
diskinfo /dev/rdisk/disk233
diskinfo /dev/rdisk/disk234

Hi There,

# dmesg
(do you see any scsci -reset done ..?)

# what does the /var/adm/syslog/syslog.log shows..?


output below following commands will take a while

Example :-
dd if=/dev/dsk/c2t1d0 of=/dev/null bs=128k
560057+1 records in
560057+1 records out

(if the records in & records out are same- meaning disk all are fine)

Disk verfication
==================
dd if=/dev/disk/disk229 of=/dev/null bs=128k
dd if=/dev/disk/disk230 of=/dev/null bs=128k
dd if=/dev/disk/disk233 of=/dev/null bs=128k
dd if=/dev/disk/disk234 of=/dev/null bs=128k

Do VG Restore
=========
vgcfgrestore n /dev/vgyzfs2 /dev/disk/disk229
vgcfgrestore n /dev/vgyzfs2 /dev/disk/disk230
vgcfgrestore n /dev/vgyzfs2 /dev/disk/disk233
vgcfgrestore n /dev/vgyzfs2 /dev/disk/disk234

Activate the VG
================

vgchange -a y /dev/vgyzfs2

the below command will re-sync - all the Pshical disk
===============================

vgsync /dev/vgyzfs2


Rgds,

Take the backup of /etc/lvmtab & use vgscan command

Thanks

The vg "vgyzfs2" does have 3 disks specified they are all DSF (device special files) so start by getting the overview.
# ioscan -m dsf
For all the 4 disk you might have a number of path to the disks. Make sure that they are working correctly.
# ioscan -fnC disk
Make sure that none of them are in the NO_HW state.

Have you analyzed the "dmesg" log output you might have a problem with you SAN connection.
