Hi ! As some of you might know, Apple has discontinued it's xServes server as of january 31st 2011. We have a server rack with 12 xserves ranging from dual G5's to dual quand-core xeon lastest generation, 3 xserve-raid and one activeraid 16 TB disk enclosure. We also use xSan to access a shared file system among the servers. Services are run from this shared filesystem, spreaded across the servers. Some LUNs on the fiber channel network are accessed directly and mounted on a case-by-case basis. Those raid volumes are partitioned with a GUID partition map, and apple_label type volumes. So they can be mounted by name with mount_hfs. We were on the verge on upgrading at least 6 of our server in a separate location (as a backup-site), with another SAN, same aplication etc. But this announce has come put a little delay. We do have several servers running CentOS (about 10 or so), on intel server platform. Now with this said, I am searching for documentation on operating a SAN under linux. We are looking at Quantum StorNext FS2 product for the SAN itselft. And I am searching info about accessing volumes on a fiber channel network by label. I know I can label individual ext3 partition, but how to do so on a raid array via fiber channel ? Basicly, I search for a linux starter guide to fiber channel storage. Thanks for any insight. Nicolas
