Obviously this depends on your lights working to some extent (the right light doing something when the right disk is accessed), but I've used: dd if=/dev/rdsk/c8t3d0s0 of=/dev/null bs=4k count=100000 which someone mentioned on this list. Assuming you can actually read from the disk (it isn't completely dead), it should allow you to direct traffic to each drive individually. Good luck, Ware _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
