9.5.2 Parameters used in remote FlashCopy commands

Figure 9-2 DS CLI remote FlashCopy commands and parameters

Most of the parameters for remote FlashCopy commands are similar to those for local
FlashCopy commands. Two major exceptions between local and remote FlashCopy
commands are:

Each remote command has the parameter

conduit

to identify the link to pass the

command to the secondary DS6000.

The local FlashCopy command

unfreezeflash

has no remote equivalent.

Figure 9-2 summarizes the parameters and the corresponding DS CLI commands that can be
used when doing remote FlashCopy.

The description of the parameters is similar to the description presented in Section 9.4.1,
“Parameters used with local FlashCopy commands” on page 73
. With regard to the
parameter

conduit

, which only applies to remote FlashCopy, the following explanation

applies:

conduit

: within a remote mirror environment, the FlashCopy commands are sent across

the mirror paths, thus avoiding the necessity of having separate network connections to
the remote site solely for the management of the remote FlashCopy. The

-conduit

parameter identifies the path to be used for transmitting the commands to the remote site.
