Command Line Interface Reference Guide

■ Specify ASYNCHRONOUS to report the write operation as complete to the

host before the data is written to the remote units of the remote copy set.

Asynchronous mode gives greater performance and faster response time,

but the data on all members of the remote copy set cannot be assumed to

be always the same.

OUTSTANDING_IOS=n

(1 to 240; default is 200)

Sets the number of outstanding I/O operations from the initiator to the target.

The way this switch operates depends on which operating mode is set by the

OPERATION_MODE switch:

■ In Synchronous mode, OUTSTANDING_IO refers to the number of

remote writes (write operations from the initiator to the target) that can be

outstanding.

■ In Asynchronous mode, OUTSTANDING_IO refers to the number of

write operations that can be reported as completed to the host before they

are written on all the members of the remote copy set.

Example

To create remote copy set RCS1, consisting of unit D1 on the local controller pair

and unit D21 on a remote controller pair (node) named London, enter:

ADD REMOTE_COPY_SETS RCS1 D1 LONDON\D21
