point me in the right direct of a document to show me how to decipher lbolt errors, or help me in identifying what may be causing the following lbolt errors please ?<BR /><BR />An ioscan reports all devices CLAIMED and to my knowledge there are no system problems.<BR /><BR />TIA,<BR />Sean<BR /><BR />Oct 26 17:59:10 jhwmss02 vmunix: SCSI: Unexpected Disconnect -- lbolt: 43545093, dev: cb001000,
