Switching SDS nodes without shutting down mode


OS Version - > SUN SOLARIS 5.11

IDS Version - > 11.70

Two nodes SDS cluster

Story :  Assume 2 nodes in SDS (Node A - Primary /  Node B - Secondary)


01. Assume current primary server (Node A) unavailable due to hardware failure.

02. Initiate the manual fail over from SDS SECONDARY(Node B) to SDS PRIMARY   > Now Node B is the PRIMARY

       onmde -d make primary <Node B Server Name > force

03. Bring Node A up after fixing the hardware problem.

04. Revert back the SDS cluster into original status using onmode command.

        onmde -d make primary <Node A Server Name >

05. Now Node B getting shutdown with the message. (After executing above command)


As explained in  #5  when shutting down, most applications and users connected to Node B sever.

So it is affecting to the users. We need to switch into Node A without  shutting down node B.


I assume this feature already in Oracle rac. Could you please consider this as an priority request and enabled in next release.

Really appreciate quick response.
