102 Performing ShadowImage for Mainframe Pair Operations Using PPRC
Value
DDNAME = dname = JCL statement identifying
the volume.
SYSNAME = sysxxx = SYSNAME in the
ASSGN system control statement.
UNITADDRESS = ccuu = device number.
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.
For a Resync request on all pairs in a CTG, set
MAnn0. where nn is the CTG ID. This request
triggers a normal Resync operation.
Secondary volume (T-VOL): SSID, serial
number, and channel connection address.
RESYNC
1
other than 1
Not applicable.
YES
NO
Primary volume CU number, or secondary
1
volume CU number.
Description
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.
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.
Re-establish a split or suspended volume pair.
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.
Copy speed of resynchronization will be
medium.
SIz does not use this parameter. SIz ignores it.
If you specify this parameter when
MODE(RESYNC) is set, the command ends
abnormally by reporting CC = 12. Do not
specify this parameter when MODE(RESYNC)
is set.
