Planned outage of the secondary system or remote path

You must split the pairs in a secondary system prior to a planned outage of the system or to a data path component (for example, switch, channel extender).

Procedure

  1. Identify the P-VOLs that are paired with S-VOL in the secondary system that is to be powered off.

For data path outage, identify all P-VOLs in the primary system that use the path or component to be powered off. You need to know the primary system, CU, and IDs (port, host group or iSCSI target, and LUN) for each of the P-VOLs.

  1. Connect to each primary system that contains affected P-VOLs, and split all affected pairs. Confirm the changed pair status.

  1. Perform the planned outage of the secondary system or data path.

  1. When the secondary system is fully powered on and ready, resynchronize the affected pairs at each primary system. Confirm the pair status changes.
