Suspending Write Operations to S-VOLs while establishing relationships
for Compatible FlashCopy
When you use FCESTABL to establish Compatible FlashCopy relationships, you can suspend the
write operations to S-VOLs. Suspending write operations to S-VOLS helps to keep data consistent.
The ACTION parameter in the following table is available, in addition to the parameters in
Table 24 (page 46) and Table 28 (page 58) .
Table 36 Parameters for the FCESTABL command (Compatible FlashCopy / In case of suspending
write operations to S-VOLs)
Description Value Parameter
Suspend the write operations from the host to S-VOLs. Although if you establish a
relationship specifying extents, the ACTION parameter will suspend the write operation
to the whole volume. FREEZE ACTION
The following example shows how to use the FCESTABL command (ACTION specified) to suspend
the write operation to an S-VOL when you establish a Compatible FlashCopy relationship. In this
example, the FCESTABL command establishes a relationship of 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.
FCESTABL SDEVN(X'4202') TDEVN(X'4203') ACTION(FREEZE)
To resume the write operation to S-VOLs, you need to issue the FCWITHDR command with the
ACTION parameter specified.
If a timeout occurs, the write operation may be resumed although you do not issue the FCWITHDR
command. The default setting of timeout is 120 seconds (2 minutes), however, you can change it.
