You may have a disk problem or a problem with alternate links.

can you do check this disk (c4t2d1)
diskinfo /dev/rdsk/c4t2d1
pvdisplay -v /dev/dsk/c4t2d1

hi amit

either this may be a problrm with the primary link or alternative link or with the disk

u can check the disk with the following commands
#diskinfo /dev/dsk/cxtxdx
the size in the o/p should be greater than zero
#ioscan -funC disk
this should show your disk .the h/w ataus should be claimed
#dd if=/dev/rdsk/cxtxdx of=/dev/null bs=64k count=100
the o/p shoud show the count of 100

if any one of these commnands failed either yr disk is failed or failing

so take the necessaary action to replace it

pls feel free to submit the points as per the solution you got from us

Amit,

The error 5 is probably pointing to device offline, may be bcus it has bad blocks and system isnt able to write to it.

Need to replace the disk probably.


BTW assigning points to members is a nice thing to do :-)

Rgds,
