If there are no update I/Os issued to the failure location, the temporary GAD pair created for migration might not be suspended. In that case, you need to forcibly delete the temporary GAD pair. First, forcibly delete the S-VOL without leaving the virtual LDEV ID. Next, forcibly delete the P-VOL leaving the virtual LDEV ID.

Command example for normal deletion:

pairsplit –g oraHA01 –S –IH0

Command example for forced deletion:

pairsplit -g oraHA01 -RF -IH2
pairsplit -g oraHA01 -SFV -IH0

Command example:

pairdisplay –g oraHA01 –fcxe –IH0
