Resynchronizing A Pair (Pairresync; Suspending Pairs (Pairsplit -R - Hitachi AMS 2000 User Manual

1. Execute the pairsplit command to split the TCE pair in the PAIR status.
he group name in the example is VG01.
•
C:\HORCM\etc>pairsplit -g VG01
2. Execute the pairdisplay command to verify the pair status and the
configuration. For example:
•
c:\horcm\etc>pairdisplay -g VG01

Resynchronizing a pair (pairresync)

To resynchronize TCE pairs
1. Execute the pairresync command. Enter between 1 to 15 for copy
pace, 1 being slowest (and therefore best I/O performance), and 15
being fastest (and therefore lowest I/O performance). A medium value
is recommended.
2. Execute the pairevtwait command to verify that the status of each
volume is PAIR. The following example shows the pairresync and the
pairevtwait commands. The group name in the example is VG01.
•
C:\HORCM\etc>pairresync -g VG01 -c 10
C:\HORCM\etc>pairevtwait -g VG01 -s pair -t 300 10
pairevtwait : Wait status done.
3. Execute the pairdisplay command to verify the pair status and the
configuration. For example:
•
c:\horcm\etc>pairdisplay -g VG01
Group PairVol(L/R) (Port#,TID, LU) ,Seq#,LDEV#.P/S,Status,Fence, Seq#,P-
LDEV# M
VG01 oradb1(L)

Suspending pairs (pairsplit -R)

To suspend pairs
1. Execute the pairdisplay command to verify that the pair to be
suspended is in PAIR status. The group name in the example is VG01.
