Steps for recovery
1. Reconnect the physical path or reconfigure the SAN to recover the path
failure.
When the path is recovered, the remote path is automatically recovered.
If you recover the physical path but the remote path does not recover,
contact Hitachi Data Systems customer support.
2. Resynchronize the pair.
a. Confirm that the P-VOL I/O mode is Local.

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

b. At the primary system, resynchronize the pair.
pairresync -g oraHA -IH0
c. Confirm that the P-VOL and S-VOL pair statuses change to PAIR
(Mirror (RL)).
