SUMMARY: Errors trying to label disk in SAN

I had two replies, from Anatoliy Nelyubin and Joe Fletcher suggesting I 
check the array permissions, and multipathing status, and maybe try 
doing a `luxadm -e forcelip' or reboot.

Fortunately in the mean time the SAN man (I think I said LAN in the 
original post) found the cause.  I needed to be on the same port as the 
LUN being served.  I'm not sure of the exact topology, but I am single 
attach at the moment, and the disk is accessible via two routes.  If I 
wasn't on the same switch as the primary controller I got this error.  
If the controller fails over to the standby, I'll be hosed again.  For 
some reason the fabric wasn't taking care of it, which doesn't bode well 
in case of a controller failure.  He's off to investigate.

Anyway, I now have a working chunk of disk.

Thanks all,
