Establishing Version 2 Relationships by Extents Using the ANTRQST Macro Command
When you establish Version 2 relationships by extents with the ANTRQST Macro command, the
parameters in
(page 103) are available.
Table 55 ANTRQST Macro Command Parameters (in Version 2)
Description Value Parameter Command
Specifies the copy source
extent (copy range) by Copy source extent (copy
range) SRCEXTENTS REQUEST=FCESTABLISH
setting the starting and
ending addresses of the
source and target with
CCHH (cylinder and head
numbers). Up to 32 extents
can be specified. When
SRCEXTENTS is not
specified, the data on all the
tracks is copied. Note that
you cannot specify this
parameter if you specify YES
for the INCREMENTAL
parameter.
Specifies the copy target
extent (copy range) by Copy target extent (copy
range) TGTEXTENTS
setting the starting and
ending addresses of the
source and target with
CCHH (cylinder and head
numbers). Up to 32 extents
can be specified. When
TGTEXTENTS is not
specified, the data on all the
tracks is copied. Note that
you cannot specify this
parameter if you specify YES
for the INCREMENTAL
parameter.
Establishing Version 2 Relationships while Suspending Write Operations to S-VOLs
When you establish Version 2 relationships with the FCESTABL command while suspending the
write operations to the S-VOLs to keep the data consistency, the ACTION parameter (see
(page 103) )
is available in addition to the parameters in (page 83) and (page 100) .
Table 56 Parameters for the FCESTABL Command (Version 2/Suspending Write Operations to
S-VOLs)
Description Value Parameter
Suspend the write operations from the
host to the S-VOLs. Note that if you FREEZE ACTION
establish a relationship specifying
extents, the ACTION parameter will
suspend the write operation to the
whole volume.
(page 104) shows an example of how to use the FCESTABL command to suspend the write operation
to an S-VOL when you establish a Version 2 relationship. In this example, the FCESTABL command
establishes a relationship for the volumes (devices) numbered 4202 and 4203, and at the same
time, suspends the write operation from the host to the source device numbered 4202.
