Hello, I've got a Netra t1 105 running 7.1-RELEASE/sparc64. The box has a pair of 9GB SCSI drives that I've configured into a geom mirror. Recently, I saw in my log: Feb 20 03:40:25 host kernel: sym0: unexpected disconnect Feb 20 03:40:43 host kernel: (da1:sym0:0:1:0): READ(10). CDB: 28 0 0 3b b2 2 0 0 20 0 Feb 20 03:40:43 host kernel: (da1:sym0:0:1:0): CAM Status: SCSI Status Error Feb 20 03:40:43 host kernel: (da1:sym0:0:1:0): SCSI Status: Check Condition Feb 20 03:40:43 host kernel: (da1:sym0:0:1:0): UNIT ATTENTION asc:29,1 Feb 20 03:40:43 host kernel: (da1:sym0:0:1:0): Power on occurred Feb 20 03:40:43 host kernel: (da1:sym0:0:1:0): Retrying Command (per Sense Data) Feb 20 03:44:26 host kernel: sym0: unexpected disconnect Feb 20 03:46:36 host kernel: (da1:sym0:0:1:0): READ(10).

No mention of da1 in dmesg whatsoever. I even did a "camcontrol devlist" and see only da0. Could I be dealing with a bad SCSI controller here? -- Regards, Doug
