2. Wait for more than 5 minutes after completing step 1, and then
resynchronize the pair.
a. Confirm that the I/O mode of the P-VOL is Local.
pairdisplay -g oraHA -fxce -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

oraHA dev1(R) (CL1-C-0, 0, 0)322222 4444.S-VOL PSUE
NEVER , 100 2222 - - 0 - - - - B/B
b. At the primary storage system, resynchronize the pair.
pairresync -g oraHA -IH0
c. Confirm that the P-VOL and S-VOL pair statuses change to PAIR
(Mirror (RL)).
pairdisplay -g oraHA -fxce -IH0

3. Using the alternate path software, resume I/O to the volume that could
not be accessed from the server (I/O might resume automatically).

Pair condition and recovery: path failure from the secondary
to external system
If the status of external system is normal, a failure might have occurred in a
physical path from primary or secondary system to the external system, or a
switch. Recover from the failure that occurred in the physical path or switch.
The following table shows transitions for pair status and I/O mode, the
volumes that are accessible from the server, and the location of the latest
