Identify internal/external disk on k370 server? is it hot swappable?

[Lucero Perez]

I am running hp ux 11.00

Usage: vgchange
{-a Availability -q Quorum [-l] [-p] [-s] [VolumeGroupName... ]}
{[-S shareable] -c cluster VolumeGroupName}
{[-P parallel_nomwc_resync_count]}
"a": A value after option must be supplied.

Should I deactivate vg?
if so, please give me a hint?

in hp ux 11.11 is there -a y option or what is the difference?

[Torsten.]

11.11 and later has the

LVM Online Disk Replacement (LVM OLR)

feature

http://docs.hp.com/en/7161/LVM_OLR_whitepaper.pdf

but it is not avail in 11.00.

Since the disk is already in NO_HW status, just confirm that vgdisplay is showing the disk c0t14d0 as unavailable - then remove it.

[Torsten.]

it's pvchange, not vgchange!

[Mridul Shrivastava]

As said earlier.. 11.00 does not have any OLR patch hence you need to deactivate the vg. For more details on LVM OLR read the following:

pvchange did not give -a option

Usage: pvchange
[-A Autobackup]
[-s] |
{[-S Autoswitch] [-x Extensibility] [-t IOTimeout] [-z SparePV]}
PhysicalVolumePath
More arguments required.


What can I do if I dont have that option?

[Mridul Shrivastava]

You need to deactivate the vg using vgchange -a n , after unmounting all the filesystems.

Then replace the disk and restore the configuration on the replaced PV and activate the VG using vgchange -a y

Hope this is clear now .

[Lucero Perez]

what happend if I only deactivate VG using vgchange and I dont umount the fs?

[Torsten.]

again: is the disk mirrored?

[Lucero Perez]

VG is mirrored by 2 disks and one of them needs to be replaced, that disk is on jamaica array.

[Torsten.]

So pull it (make sure to pull the correct one) and proceed with the steps you wrote earlier.
