Tagging and SCB paging enabled. I sometimes get errors of the form: sd0(ahc0:0:0): ABORTED COMMAND asc:41,86 Vendor Specific ASCQ, retries:4 only under high load and on multiple different disks (as far as I can reproduce the problem). This sometimes results in errors like: vnode_pager_putpages: I/O error 5 vnode_pager_putpages: residual I/O 4096 at 5816 and various sorts of crashes. Can anyone tell me how to decode these? I've got some docs from Quantum and they indicate that this error is some sort of data path error, whatever that is. I have a bunch of identical disks in a 2.2-GAMMA machine and have never seen a similar error. Any ideas? -- Alan Judge Phone: +353-1-6046901 Indigo Internet Services Fax: +353-1-6046948
