You must confirm that the replaced nodes have connectivity to the disk shelves at the surviving site.

About this task

This task is performed on the replacement nodes at the disaster site.

This task is performed in Maintenance mode.

Steps

  1. Display the disks that are owned by the original system ID.

    disk show -s old-system-ID

    The remote disks can be recognized by the 0m device. 0m indicates that the disk is connected via the MetroCluster iSCSI connection. These disks must be reassigned later in the recovery procedure.

    *> disk show -s 4068741256
Local System ID: 1574774970
