Major os-unix@ testlab.dc-dublin.de vmunix: LVM: VG 64 0x050000: PVLink 31 0x010000 Failed! The PV is still accessible.

Solution:

Use this comand to find out which disk having alerts, these commands output will give you the disk device file
Syntax:ll /dev/dsk/* | grep 010000


testlab:/dev#ll /dev/dsk/* | grep 010000
brw-r-----   1 bin        sys         31 0x010000 Nov  9  2010 /dev/dsk/c1t0d0

Then check the ioscan -fnC disk and see this disk is CLAIMED

testlab:/dev#ioscan -kfnC disk /dev/dsk/c1t0d0
Class     I  H/W Path  Driver S/W State   H/W Type     Description
==================================================================
disk      3  0/4/1/0.80.0.39.0.0.0  sdisk   CLAIMED     DEVICE       HITACHI OPEN-V
                      /dev/dsk/c1t0d0   /dev/rdsk/c1t0d0

diskinfo /dev/rdsk/if it displays the full size of disk

testlab:/dev#diskinfo /dev/rdsk/c1t0d0
SCSI describe of /dev/rdsk/c1t0d0:
             vendor: HITACHI
         product id: OPEN-V
               type: direct access
               size: 83653632 Kbytes
   bytes per sector: 512

Then try the dd command to find any error in the block device
Syntax: dd if=/dev/dsk/cxtxdx of=/dev/null bs=1024

testlab:/dev#dd if=/dev/dsk/c1t0d0 of=/dev/null bs=1024
