Not that I expect any relevance to your problem though.. Is there anything else (other servers) connected to the HSG? What kind of FC switch do you have? If it is a Brocade FC switch, what firmware do you run on the switch? > da0 at isp0 bus 0 target 129 lun 1 > da0: <DEC HSG60 V85L> Fixed Direct Access SCSI-2 device > da0: 100.000MB/s transfers, Tagged Queueing Enabled > da0: 103101MB (211152379 512 byte sectors: 255H 63S/T 13143C) Can I please have a SHOW THIS FULL, a SHOW CONNECTIONS, a SHOW UNITS, a SHOW STORAGE from the HSG? > I have this disk mounted as /mnt.
