ESTPAIR (Resynchronizing Pairs)
Table 7-9 lists and describes the ESTPAIR command parameters that can be
used when you resynchronize SIz pairs.
Table 7-9 ESTPAIR Command Parameters (Resynchronizing Pairs)
Parameter Value Description
DDNAME,
SYSNAME, or
UNITADDRESS
DDNAME = dname = JCL statement
identifying the volume.
SYSNAME = sysxxx = SYSNAME in the
ASSGN system control statement.
UNITADDRESS = ccuu = device number.
You should specify only one parameter of the
three parameters. The italic part on the left
means that it is the arbitrary name. For
example, dname means the arbitrary unique
name of the JCL statement which identifies the
volume.
PRI Primary volume (S-VOL): SSID, serial
number, and channel connection address.
You can set an additional parameter
corresponding to each request instead of a
serial number.
For a Quick Resync request, set MRF00. This
parameter is valid for MODE(RESYNC) only.
For a Quick Restore request, set MRQ00. This
parameter is valid for MODE(RESYNC) only.
For a Reverse Copy request, set MRR00. This
parameter is valid for MODE (RESYNC) only.
If you set a parameter other than the parameters on
the left, the command will be rejected.
Caution: When a Quick Restore operation or a
Reverse Copy operation is required and if you specify
NO for the ONLINSEC parameter, the job will end
abnormally by reporting CC = 12. If you specify YES
for the ONLINSEC parameter, you may execute the
job. However, note that the copying operation is
performed without any online check.
SEC Secondary volume (T-VOL): SSID, serial
number, and channel connection address.
MODE RESYNC Re-establish a split or suspended volume pair.
1 Copy speed of resynchronization will be slow,
except when the DKC emulation type is 2105 or
2107. When the DKC emulation type is 2105 or
2107, the copy speed of resynchronization is
always medium regardless what you specify for
the PACE parameter.
PACE
other than 1 Copy speed of resynchronization will be medium.
CRIT Not applicable. SIz does not use this parameter. SIz ignores it.
MSGREQ YES
NO
If you specify this parameter when MODE(RESYNC)
is set, the command ends abnormally by reporting
CC = 12. So, please do not specify this parameter
when MODE(RESYNC) is set.
LSS Primary volume CU number
*1
, or secondary
volume CU number
*1
.
ONLINESEC
*2
YES
Pair resynchronize operation (forward) will be
performed whether the T-VOL is online or not.
Pair resynchronize operation (backward) will be
performed whether the S-VOL and T-VOL are online
or not.
