remove vg on cluster HP-UX

[STL]

what are the step for remove e volume group on cluster Hp-UX?

on node a: lvremove, vgremove, pvremove

on node b: ????

vgexport e vgimport are use only for create?

[Steven E. Protter]

Shalom Carlo,

Node b: vgexport the volume group.

Node a: lvremove vgremove.

That should be sufficient.

You can also vgexport on both nodes.

vgchange -a n vg##

Make sure the thing is deactivated before you start.

To remove?

vgchange -c n vgXX

You can do the lvreduce, vgreduce....or just do a vgexport vgXX.

On node b, just a vgexport vgXX

Also,emove from any package control scripts.

- vgremove vg
- pvremove

Quorum not present, or some physical volume(s) are missing.

?????? how i remove the the pv,vg,lv on node b ??????

[Geoff Wild]

pvremove - you destroyed the vg data on the disk - so node b can not see it anymore...

Just do a vgexport on node b

Hi,

As long as you dont need tha VG anymore, you can use #vgexport to remove the VG info from the system.

This dosent remove the data in the DISKs. If you need to get this VG in some other system you can do #vgimport to get the VG back. If this is the case you can take a map file during the export, so that you can get the same lvol name etc.

With Regards,

Siva.

Hi,

If the volumegroup doesn't belong to a package anymore, then just execute

vgexport /dev/vgxx on each node
