[UniMacTech] connecting a SUN (Storagetech) SAN to an xserve via fibre channel?

[Robert Davy]

Mark,

We have in the past connected LUNS from our Storagetech 6140 and D280  
SAN arrays to Macs.  The main thing in a fabric is to make sure that  
the Mac is allowed to see the disk LUN.  There are usually two areas  
where this needs to be done: On any Fibre channel switches that are  
between the array and the Mac, and also on the array itself.  Ask your  
sysadmin to make sure that he can see the WWN for you mac on his  
array, and he has added it to the hosts allowed to mount that LUN.

Rob.
