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)

.

Suspend the write operations from the
host to the S-VOLs. Note that if you
establish a relationship specifying

“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.
