Workflow to recover from a failure that requires replacing journal volumes

Use the following workflow to recover from a failure on the UR delta resync pair due to a journal volume failure on the storage system at the GAD secondary site that requires replacing the journal volume.

1. Set the system option mode 1182 to ON at the GAD secondary storage system.
2. Add a reserve journal volume.

   After a reserve journal volume is added, the UR delta resync pair status changes to PSUE, and the SIM code dc9xxx or 7ff103 is issued.

   If a reserve journal volume has already been added, delete the reserve journal volume from the journal, and then add a reserve journal volume again.

3. Delete the journal volume in which a failure occurred, from the journal.
4. Resynchronize the UR delta resync pair to restore its status from the failure.

   Command example:

   pairresync -g oraDELTA -hold y

5. Confirm that the status of the P-VOL of the UR delta resync pair is PSUS.

   If the server has stopped I/Os, the status is PSUE.

   Command example:

   pairdisplay -g oraDELTA -fxce -IH1
   Group     PairVol(L/R)  (Port#,TID, LU),Seq#,  LDEV#.P/S,  
   Status,Fence, %,  P-LDEV#  M  CTG  JID  AP  EM  E-Seq#  E-LDEV#  R/W
   oraDELTA  dev3(L)       (CL1-A-1, 0, 1) 822222 4444. P-VOL 
   PSUS   ASYNC ,0   6666     -  0    0    -   -   -       -       -/-
   oraDELTA  dev3(R)       (CL1-A-1, 0, 1) 844444 6666. S-VOL 
   SSUS   ASYNC ,0   4444     -  0    0    -   -   -       -       -/-

6. Confirm that the mirror status of the journal of the UR delta resync pair is PJNS.

   Command example:

   pairdisplay -g oraDELTA -v jnl -IH1
   JID  MU  CTG  JNLS  AP  U(%)  Q-Marker  Q-CNT  D-SZ(BLK)  Seq#   Num  LDEV#
   000  1   1    PJNS  4   21    43216fde  30     512345     62500  1    39321 

7. Set the system option mode 1182 to OFF at the GAD secondary storage system.
8. Confirm that no failure SIMs are displayed.
