VxVM DG Import problem

[Mohamed Amine]

Hello everyone,

I have a disk group with two disks, I have deported it and want to import it back.
The disk are only visible to one node. But anytime I try to do so, here what happens :

# vxdg import vg_ccbs_crs
VxVM vxdg ERROR V-5-1-10978 Disk group vg_ccbs_crs: import failed:
Disk is sharable, operation not supported

After checking the disk status here what I get :
# vxdisk -s list c8t0d2
Disk: c8t0d2
type: auto
flags: online ready private autoconfig shared autoimport
guid: {1957d08a-1dd2-11b2-9f46-001f290de7e3}

One of the disks is flagged as shared even though it shouldn't.
Anyone has any clue about clearing the flag ?
Thanks.

Hi Mohamed,

Have a look at this doc.

Thanks for your prompt answer.
Actually, the node is part of the cluster but this DG is not shared. I don't really know how we managed to get one of the disks shared !

If I try to import the disk in shared mode, it won't work as the second node can't see it

VxVM vxdg ERROR V-5-1-10978 Disk group vg_ccbs_crs: import failed:
Cannot find disk on slave node

Is there any way to clean the shared flag on the disk or to force the import of the DG in shared mode ?

Thanks

Hi again,

The shared lun /disk is probably configured as the cluster quorum device.

What kind of cluster are you running?

Hello,

I'm running SG CFS eRAC on HPUX.
cmgetconf gives me :
FIRST_CLUSTER_LOCK_PV /dev/dsk/c8t7d1
It's not the disk lock seems to be.

I thought of removing the node from the cluster and trying to import, what do you think ?

Thanks

Hi

See what is on the disk itself and if there is nothing on it then remove it.

vxprint -l -g group_name
vxdg -g group_name rmdisk disk_name

try
vxdg -Cf import dg_name

Thanks a lot. That fixed my problem.
As the disks were only visible on one node, I could just clear the import data on the disk.

I could use "vxdisk clearimport c8t0d2" as well
