Recover from the failure in the remote path.

Verify the pair status of the target GAD pair.

Command example:

pairdisplay –g oraHA02 –fcxe –IH2
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
oraHA02 dev02(L) (CL1-C-0, 0, 0)833333 1111.P-VOL PSUE
NEVER , 100 2222 - - 2 1 - - - B/B - D
N D
oraHA02 dev02(R) (CL1-C-0, 0, 0)844444 2222.S-VOL SSWS
NEVER , 55 1111 - - 2 1 - - - L/L - 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 S-VOL of the target GAD pair is SSWS(Local):
  1. Continue data migration using the procedure described in Deleting the source GAD pair and the temporary GAD pair for data migration.
  2. Resynchronize the target GAD pair by specifying the S-VOL.
    Command example:
```
pairresync –g oraHA02 -swaps –IH3
```
  3. Verify that the copy operation for the target GAD pair is complete, and then verify that the pair status has changed to PAIR.
    Command example:
```
pairdisplay –g oraH02 –fcxe –IH3
Group PairVol(L/R) (Port#,TID, LU),Seq#, LDEV#.P/S,
Status,Fence,%, P-LDEV# M CTG JID AP EM E-Seq# E-LDEV#

```
- If the pair status (I/O mode) of the P-VOL of the target GAD pair is PSUE(Local):
  1. Resynchronize the target GAD pair by specifying the P-VOL.
    Command example:
```
pairresync –g oraHA02 –IH2
```
  2. Verify that the copy operation for the target GAD pair is complete, and then verify that the pair status has changed to PAIR.
    Command example:
```
pairdisplay –g oraH02 –fcxe –IH2
