PPRC Support = Yes

◦

Service SIM of Remote Copy = Not Report

◦

Initial copy priority, the CFW (cache fast write) Data option, and DFW (DASD fast write) to

R-VOL option. If CESTPAIR is used to create a pair, the following values are used for these

options. Use Remote Web Console to change these options.

Initial copy priority = 0

◦

CFW Data = Copy to R-VOL. If you select the only M-VOL value, the data set that is

◦

updated by CFW in the M-VOL cannot be used in the R-VOL. To use this data set in the

R-VOL, release the pair and format the data set.

◦

CFW Data = only M-VOL can be set with a PPRC command when the Remote Copy

Function Switch is used. Contact your HP account team for more information.

◦

DFW to R-VOL = DFW not required. This setting does not affect M-VOL I/O performance.

If one side of cache is closed due to a remote system failure, the copy operation still uses

DFW. The difference between not required and required is that new pairs cannot be

established with the required option when one side of RCU cache is closed. In this case,

the Add Pair operation fails (This restriction applies only when the CU emulation type of

RCU is 3390).
