Here is the output of lspv.

It does look like I have a disk that is unassigned, "hdisk42", so I'd like to put this one in use while I get 2 other disks to replace with.
I was going to try and remove hdisk31 and put hdisk42 in its place..
My notes for removing, swapping the failed disk and adding a new one in for AIX 7.1 are as follows..
Quote:
1) Unmirror hdisk31
unmirrorvg -c 1 vg_usr1 hdisk31
2) Take the disk out of the VG
reducevg vg_usr1 hdisk31
3) Remove the disk from system configuration
rmdev -dl hdisk31
4) Replace the disk
5) Get the disk back to the system configuration
cfgmgr
6) Add the disk to the VG
extendvg vg_usr1 hdisk31
7) Mirror hdisk31 again
mirrorvg -S -c 2 vg_usr1
"-S" will synchronize the stale partitions in the background.
8) After some time "lsvg vg_usr1" should show "STALE PPs: 0"
However, something is not happy, I can't get passed the first step.
Code:
# unmirrorvg -c 1 vg_usr1 hdisk31
0516-1155 lreducelv: Last good copy of a partition cannot reside on a missing disk.
Try again after reactivating the disk using chpv and varyonvg.
0516-922 rmlvcopy: Unable to remove logical partition copies from
logical volume lv_usr1.
0516-1135 unmirrorvg: The unmirror of the volume group failed.
The volume group is still partially or fully mirrored.
Then I tried varyonvg. no success.
Code:
# varyonvg vg_usr1
varyonvg # 0516-934 /usr/sbin/syncvg: Unable to synchronize logical volume lv_usr1.
0516-932 /usr/sbin/syncvg: Unable to synchronize volume group vg_usr1.

This may sound like an absolute rookie question, and it is.
I have been working on Migrating our HP and Solaris servers to the new EMC SAN and know the routines backwards.
Now we've suddenly got a new IBM server and I don't even know how to check if it is connected to the switch.
Can someone... (1 Reply)
We run two p5 nodes running AIX 5L in a cluster mode (HACMP), both the nodes share external disk arrays. Only the primary node can access the shared disks at a given point of time.
We are in the process of adding two new disks to the disk arrays so as to make them available to the existing... (3 Replies)
