Recover from the failure in the remote path.

Verify the pair status of the source GAD pair.

Command example:

pairdisplay –g oraHA00 –fcxe –IH0
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
QM DM P PR
oraHA00 dev00(L) (CL1-C-0, 0, 0)411111 1111.P-VOL PSUE
NEVER , 100 2222 - - 0 1 - - - B/B - D

Perform either of the following recovery procedures depending on the pair status (I/O mode).
- If the pair status (I/O mode) of the P-VOL of the source GAD pair is PSUE(Local), continue data migration using the procedure described in Suspending the source GAD pair by specifying the P-VOL.
- If the pair status (I/O mode) of the S-VOL of the source GAD pair is SSWS(Local):
  1. Resynchronize the source GAD pair by specifying the S-VOL.
    Command example:
```
pairresync –g oraHA00 -swaps –IH1
```
  2. Wait until the copy operation for the source GAD pair is complete, and then verify that the pair status has changed to PAIR.
    Command example:
```
pairdisplay –g oraHA00 –fcxe –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 QM DM P PR
oraHA00 dev00(R) (CL1-C-0, 0, 0)422222 2222.S-VOL PAIR
NEVER , 100 1111 - - 0 1 - - - L/M -
D N D
oraHA00 dev00(L) (CL1-C-0, 0, 0)411111 1111.P-VOL PAIR
NEVER , 100 2222 - - 0 1 - - - L/M -
D N D
```
    After performing the procedure, continue data migration using the procedure described in Suspending the source GAD pair by specifying the P-VOL. However, in the configuration of this disaster recovery, the S-VOL of the source GAD pair shares the LDEV with the P-VOL of the temporary GAD pair. Therefore, take the host path to the P-VOL of the source GAD pair offline, and then suspend the source GAD pair by specifying the S-VOL during the procedure described in Suspending the source GAD pair by specifying the P-VOL.
