Re: Hard disk error

Hi,

The document mentioned in the earlier post is complete withint itself. But still if you are founding it too much for looking for your solution then here are simple steps which should be used when application is not used much (Utilization on the data you are copying is less as it will badly impact performance when you copy the data across if you do it with application running)

Assumption - you have a free slot to host a new disk and you current disk is not mirrored.

Insert new disk of same or more size to the empty slot and check the OS detects it in ioscan. Create its device file with insf.

#ioscan -fnC disk
#insf

Let us say the new disk device file is /dev/dsk/cxtydz

#pvcreate /dev/rdsk/cxtydz
#vgextend /dev/vg002 /dev/dsk/cxtydz

Case -1
==========
Now if you have mirror-Ux installed. Create a copy of the data on /dev/dsk/c5t0d0 onto new disk.

#lvextend -m 1 /dev/vg002/lvolxx /dev/dsk/cxtydz

#lvextend -m 1 /dev/vg002/lvolxy /dev/dsk/cxtydz

Repeat this for all the LVs in this faulty disk.

Once this is done reduce the copy from the faulty disk.

#lvreduce -m 0 /dev/vg002/lvolxx /dev/dsk/c5t0d0

Repeat for all the LVs in the faulty disk.

At last your faulty disk will have no LVs and you can reduce VG from this disk and can finally remove it.

#vgreduce /dev/vg002 /dev/dsk/c5t0d0


Case -2
==========

Now if mirror-Ux is not installed, do a pvmove for all the LEs on faulty disk to new disk.

#pvmove /dev/dsk/c5t0d0 /dev/dsk/cxtydz

Caution - There is a potential risk of disk completely going bad in this so take a good backup prior to attempting both of these options.
