Import Cluster Disk Group onto host that is not part of the cluster

Hi All,

We are using CFSHA 5.1 on a oracle cluster group running on EMC LUNs (Solaris 10). The EMC engineer has created some scripts to fracture and sync the lun clones to do backups. However we are unable to import the clone LUNs to the backup server; the following errors are reported:

vxvm:vxdg: ERROR: Disk group oradg: import failed: Disk is sharable,

operation not supported

Is it possible to import cluster disk group onto a host that is not part of the cluster?

 

Thanks,

CK

    Hi All,

    The solution is to run the following command to import the CFS disk group onto another host that is not part of the cluster and has no CFS licensed:

    vxdg -Cf import <Disk_Group>

    Thanks

    Hello,

    To answer your question, a normal diskgroup which doesn't have a "shared" flag can be imported on a standalone node however a diskgroup with shared flag can not be imported as shared disk group on standalone node.

    It seems like you are using CFS/CVM on the primary site & that is why you have parallel diskgroups or shared diskgroups (you can verify via "vxdg list" command) while on secondary if you have standalone server (no CFS/CVM installed) you are facing this error.

    So you have two ways to go:

    1. As I understand from description you gave, you are cloning disks from primary so all the private region is getting copied as well ... so your backup server finds all the diskgroups as shared diskgroups. You can modify your script to import the diskgroups as normal diskgroups (use "vxdg import " instead of "vxdg -s import" ), hope this should work out.

    2. Create a one node CFS/CVM on backup server, you will need to install complete product suite here...

     

    Hope this helps
