I have a FC San with 80 disk. The controller head quit working and instead of replacing the head I have created a software Raid 5. This all works. The problem is windows reports that disk 70 is bad and so I would like to replace it only I have no way of knowing which one it is? What am I missing on this? since this is 5 enclosures I can't possibly know which disk that windows calls "Disk 70"

    Accepted Solution

    The disk should have flashing lights that will flash a different color on the disk.  Otherwise, open your SAN software.  Most includes a graphical display of your SAN and you should be able to identify the faulty disk.

    if it is SCSI, you may be able to find the Drive ID in the SCSI configuration utility.

    You would think that windows could flash a red light on a bad disk! oh well.... I think it must be the controller card/head with those type features.

    I did manage to get the disk back online and started it formatting. The green activity light flashes so I managed to find this disk. As for the San software well it works with the controller head. What I have, without the controller head is JBOD "just a bunch of disks"

    Any ideas on this? I suppose I could call Microsoft. I'm sure windows knows which disk is which....... I can't get windows to give me that information.
