Hi Admins,

OS --> AIX 5.3

Problem summary :

one of the VG consists 4 internal hdisks with 1 Logical volume. One of the disk hdisk2 has some hardware problem and needs to be replaced with new disk.
Currently hdisk2 is very much accessible.As a proactive step we are replacing the disk.

Scenario : 1 VG --> 4 disks --> 1 LV

steps to replacement

vgreduce <vgname> hdisk2
replace the disk
cfgmgr
vgextend <vgname> <new disk>
restore the backup of hdisk2 into newdisk

Backup of hdisk2 will be taken before replacement.After replacement and restoration , how new disk will sync with other available disks.
Please let me know the standard steps to replace a disk

Thanks in advance

Hello Himacs ,
I think it will be easier if you add the new disk
And add it to the vg then use migratepv from hdisk2 to the new disk.
Let me know if this solution works at your env.

Hi Ahmed,

Thanks for the response.migratepv is the good option .But free slot should be there to insert newdisk.Because we can only remove old disk after migratepv.

Suppose if, free slot is not there ,then how to proceed.
