Hi Neale, you've received device check conditions (ASC/ASCQ says "Logical unit not supported", see http://www.arkeia.com/resources/scsi_rsc.html). Please verify your SAN configuration. Double-check whether your hosts on the Shark box are properly configured (allow access to the correct WWPNs of the FCP CHPIDs) and whether you've chosen the right LUNs in your zfcp configuration.
