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
“Parameters
for the FCESTABL Command (Version 2/Suspending Write Operations to S-VOLs)” (page 106) ) is
available in addition to the parameters in “Parameters for the FCESTABL Command (Version
2/Volume Copying)” (page 84) and “Parameters for the FCESTABL Command (Version 2/Dataset
Copying)” (page 103) .
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
establish a relationship specifying
extents, the ACTION parameter will
suspend the write operation to the
whole volume. FREEZE ACTION
“FCESTABL Command (Version 2/ACTION Specified)” (page 107) 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.
