VCS Replication agent for non-cluster disk group

hi,

with servers having internal raid controller, you can create a lun that you put in a diskgroup and then you can use VVRAgent without shared disks.

From a Windows perspective - currently under investigation.

Any update on this ? I have heard that there is patch available for this issue.

I got patch fot this from Symantec. The patch number is 2030655. This one allows me to import DG as clustered on internall controller. Thank you Symantec.

Hello,

it's very interresting, but i learned that it was a private patch... could Symantec talk about it ?

many thanks,

Regards

The diskgroup agent requires a cluster diskgroup (and VVR agent requires you to specify diskgroup resource via VMDgResName resource).  However you can create a cluster diskgroup on a non-shared disk using vxlcus command:

Run:

vxclus UseSystemBus ON

This command allows a cluster disk group to be created that can reside on the same bus as the
cluster node’s system or boot disk (i.e an internal, non-shared disk).

If you already have a local diskgroup, then you need to make this a cluster DG, so:

vxdg -g dg_name deport

vxdg -g dg_name -s import

The import command will fail if you have not run "vxclus UseSystemBus ON" first as it will say a cluster diskgroup cannot be on SystemBus.  You can do the import/deport commands in the GUI if you like (just tick "Import as cluster disk group"), but I am not sure if you can do equiv on vxclus in the GUI.

Now you can set-up Diskgroup and VVR resources in VCS.
