328 Chapter 4 Performing CCI Operations
4.21.2.3 TrueCopy Using Dual Hosts
In the following example, the pair-operation command (except the -l option) determines
whether the operation for paired volumes should be permitted at a remote site. The result is
that the paircreate command is not allowed to operate the paired volume, because the
volume described on HostB differs from the SLPR of the command device. Also, the raidscan
-p CL3-A command (on HostB) will not be allowed to scan a port.
