Sun Cluster Geographic Edition System Administration Guide

Resynchronizing a Partnership

Partner clusters that become disconnected during a disaster situation might force the administrator to perform a takeover for a protection group that the partners share. When both clusters are brought online again, both partner clusters might 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 cluster.

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 do not need to resynchronize the configuration information in the following situations if the original secondary cluster goes down and resumes operation later.

Use the geoadm status command to check whether you need to resynchronize a partnership. If the Configuration status is Synchronization Status Error, you need to synchronize the partnership. If the Local status is Partnership Error, do not resynchronize the partnership. Instead, wait until a heartbeat exchange occurs.

ProcedureHow to Resynchronize a Partnership

Before You Begin

Ensure that the following conditions are met:

Caution – Caution –

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

  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 partnershipname

    Specifies the name of the partnership
