Dear SAN Admins:  I am trying to add a couple of LUNS to a Linux Server after a long long time. (which already has a few LUNs from the very same DMX). I am sure I am missing something. I am unable to discover the LUNs on the Linux Box. I get these messages in the log file of the Linux Server.       May　 1 14:09:50 kernel: scsi: host 0 channel 0 id 0 lun99 has a LUN larger than allowed by the host adapter   What would you suggest? Any input would be most appreciated.  KGD.  May　 1 14:09:50 kernel: scsi: host 0 channel 0 id 1 lun88 has a LUN larger than allowed by the host adapter
