Verify that the pair status (I/O mode) of the temporary
GAD pair is PSUE(Local) for the P-VOL and COPY(Block) for the S-VOL.
Command example:
pairdisplay –g oraHA01 –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 oraHA01 dev01(L) (CL1-C-0, 0, 0)411111 1111.P-VOL PSUE NEVER , 55 1111 - - 1 1 - - - L/L - D N D oraHA01 dev01(R) (CL1-C-0, 0, 0)833333 1111.S-VOL COPY NEVER ,----- 1111 - - 1 1 - - - B/B - D N D
-
Forcibly delete the S-VOL of the temporary
GAD pair by deleting the virtual LDEV ID.
Command example:
pairsplit –g oraHA01 –RF –IH2
-
Forcibly delete the P-VOL of the temporary
GAD pair by leaving the virtual LDEV ID.
Command example:
pairsplit –g oraHA01 –SFV –IH0
-
Verify that the temporary
GAD pair has been deleted.
Command example:
pairdisplay –g oraHA01 –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 oraHA01 dev01(L) (CL1-C-0, 0, 0)411111 1111.SMPL ---- ------,----- ----- - - - - - - - -/- - - - - oraHA01 dev01(R) (CL1-C-0, 0, 0)833333 1111.SMPL ---- ------,----- ----- - - - - - - - -/- - - - -
-
Verify that the virtual LDEV ID remains for the P-VOL of the source
GAD pair.
Command example:
raidcom get ldev –ldev_id 0x1111 –IH0 (Omitted) LDEV : 1111 (Omitted)
-
Verify that the
GAD reserve attribute is assigned to the virtual LDEV ID of the S-VOL of the temporary
GAD pair.
Command example:
raidcom get ldev –ldev_id 0x1111 –IH2 (Omitted) LDEV : 1111 VIR_LDEV : ffff
-
Resynchronize the source
GAD pair by specifying the S-VOL.
Command example:
pairresync –g oraHA00 –swaps –IH1
-
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.P-VOL PAIR NEVER , 100 1111 - - 0 1 - - - L/M - D N D oraHA00 dev00(L) (CL1-C-0, 0, 0)411111 1111.S-VOL PAIR NEVER , 100 2222 - - 0 1 - - - L/M - D N D
-
Reverse the P-VOL and the S-VOL of the source
GAD pair.
Command example:
pairresync –g oraHA00 –swaps –IH0
-
Verify that the P-VOL and the S-VOL of the source GAD pair have been
switched and the pair status has changed to 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 PAIR NEVER , 100 2222 - - 0 1 - - - L/M - D N D oraHA00 dev00(R) (CL1-C-0, 0, 0)422222 2222.S-VOL PAIR NEVER , 100 1111 - - 0 1 - - - L/M - D N D
