Volume shadowing between FC Storage at different sites, and the allocation class

Hi,

I have just connected to some Fibrechannel based storage from my VMS
system. I see all the devices as $1$DGAxxx. Even thought the ALLOCLASS
parameter is 6 for the system.

This system will be in a cluster with a system at a remote site also
connected to FC storage, and I am sure I will also see the devices as
$1$DGAxxx.

I want to use Volume Shadowing to mirror the two sites, but I am a bit
concerned that because the allocation class is 1 for fibre channel
storage at both sites this may cause confusion for the cluster
software.

If anybody else has done this or has suggestions I would appreciate
the feedback.

With regards
Andrew
