Figure 74 Operation across SLPRs using two command devices on dual hosts
To operate SLPR#N, share the command device. If HostB has a shared command device for SLPR#N,
the paircreate command is permitted. Also, the raidscan -p CL3-A command (via HostA),
is allowed to scan a port because the shared command device has the Bitmap settings SLPR#M
and SLPR#N.

Continuous Access Synchronous 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) is not allowed to scan a port.
