Hi I have an OpenIndiana server connected to a 12 drive JBOD chassis through SAS, and I am trying to figure out the best way to find out which physical drive in the chassis resolves to each of the drive names visible from the operating system.
These are the drives I can see in OpenIndiana related to the JBOD (list from "format"): c8t5000CCA369C3AF7Dd0 c8t5000CCA369C5B1DBd0 c8t5000CCA369C5B22Bd0 c8t5000CCA369C5B44Cd0 c8t5000CCA369C5BB0Cd0 c8t5000CCA369C5BC27d0 c8t5000CCA369C5C30Cd0 c8t5000CCA369C5CD7Cd0 c8t5000CCA369C5CF1Ad0 c8t5000CCA369C248F7d0 c8t5000CCA369C03102d0 c8t5000CCA369C40412d0 The names does not tell anything about which physical location they have in the JBOD as each drive has a WWN name, or at least a WWN-like name. The only way I have found which I can find the order of the drives in the JBOD along with the above names, without pulling out each drive and see which one becomes unavailable, is within /etc/path_to_inst, where I find the following lines: "/scsi_vhci/disk@g5000cca369c248f7" 3 "sd" "/scsi_vhci/disk@g5000cca369c5c30c" 4 "sd" "/scsi_vhci/disk@g5000cca369c3af7d" 5 "sd" "/scsi_vhci/disk@g5000cca369c40412" 6 "sd" "/scsi_vhci/disk@g5000cca369c5bc27" 7 "sd" "/scsi_vhci/disk@g5000cca369c5b1db" 8 "sd" "/scsi_vhci/disk@g5000cca369c5cd7c" 9 "sd" "/scsi_vhci/disk@g5000cca369c5b44c" 10 "sd" "/scsi_vhci/disk@g5000cca369c5bb0c" 11 "sd" "/scsi_vhci/disk@g5000cca369c5b22b" 12 "sd" "/scsi_vhci/disk@g5000cca369c5cf1a" 13 "sd" "/scsi_vhci/disk@g5000cca369c03102" 14 "sd" The order of the drives here match the order in which they are found in the JBOD, I just have to subtract 2 from the number in the second column. My worries are however how this will look if I get another JBOD chassis attached to the same server, I guess it will just continue with counting the numbers up, but I don't have any reference to which chassis each drive is found in. Does anybody have a better way of getting the SAS drive IDs mapped to the physical drive positions in JBOD arrays? -- Venlig hilsen / Kind regards Jeppe Toustrup (aka.
