Resynchronizing a Partnership

Partners become disconnected during a disaster situation, forcing the administrator to perform a takeover for a protection group that the partners share. When both clusters are brought online again, both partner clusters report as the primary of the protection group. You must resynchronize the configuration information of the local protection group with the configuration information that is retrieved from the partner.

If a cluster that is a member of a partnership fails, when the cluster restarts, it detects whether the partnership parameters have been modified while it was down. You decide which partnership configuration information you want to keep: the information on the cluster that failed or the information on the failover cluster. Then, resynchronize the configuration of the partnership accordingly.

You can detect that a partnership needs to be resynchronized by looking at the output of the geoadm status command. If the Configuration status is Synchronization Status Error, the partnership needs to be synchronized. If the Local status is Partnership Error, you should not resynchronize the partnership. Instead, wait for the heartbeat exchange to occur.

How to Resynchronize a Partnership

Before You Begin

Before you resynchronize a partnership, ensure that the following conditions are met:

• The local cluster is Sun Cluster Geographic Edition enabled.

• The local cluster was an active member of the partnership before failing.

Resynchronizing a partnership overwrites the partnership configuration on the cluster where the command is run with the information from the partner cluster.

Steps

1. Log in to a node on the cluster that needs to be synchronized with the information retrieved from the partner cluster.

   You must be assigned the Geo Management RBAC rights profile to complete this procedure. For more information about RBAC, see Sun Cluster Geographic Edition Software and RBAC.

2. Resynchronize the partnership.

   # geops update partnership-name

   partnership-name

   Specifies the name of the partnership
