Hi,
on my HP-UX11.31 MC-SG 11.20 cluster, I'm planning to add new disks to the VG in a fail-over package. Could you please verify the steps I'm going to take?:
1. on primary node: pvcreate NEW_PV
2. on primary node: vgextend VG_DATA NEW_PV
3. on primary node: vgexport -p -s -v -m VG_DATA.map VG_DATA; scp VG_DATA.map to secondary node
4. on secondary node: vxexport VG_DATA
5. on secondary node: vgimport -s -m VG_DATA.map NEW_PV
6. it's done.
I believe vgimport the data VG is safe as it doesn't write anything to the disk. Could anyone please confirm?
Thanks.
Alex

Re: vgimport data VG on secondary node without de-activate data VG on primary node in MC-SG
In between steps 4 and 5 you may need to create the /dev/VG_DATA directory and /dev/VG_DATA/group file.
With HP-UX 11.31 the vgcreate command will automatically create those, but I do not know if the vgimport command will do that. If it does not, you will have to do that manually.

Re: vgimport data VG on secondary node without de-activate data VG on primary node in MC-SG
anyone could confirm whether this can be done without deactivating the vg on primary node?
