This section describes the procedure for starting operations to have the normal operation status of GAD+UR (UR delta resync pair status changes from PSUE to PSUS) after each pair of GAD+UR is created. After the following procedure, the GAD+UR configuration is ready for normal operation as shown in Configuring GAD 3DC delta resync.

  1. Issuing update I/O to P-VOL/GAD S-VOL: To have the normal GAD+UR operation status, keep updating I/O to P-VOL or GAD S-VOL and wait for two minutes.
    If update I/O is issued to P-VOL or GAD S-VOL, the status information of GAD+UR is reported among the primary, GAD secondary, and UR secondary storage systems. At the time, the UR delta resync pair status is changed from PSUE to PSUS.
  2. Checking UR delta resync pair status and mirror status: Confirm in the GAD secondary storage system the UR delta resync pair status and the mirror status of the journal. Confirm that the UR delta resync pair status is HOLD. In CCI, the pair status of the P-VOL is displayed as PSUS, and the mirror status of the journal is displayed as PJNS.
