    The system is GS140, the storagework is hsz70, with scsi connection.

    The system is running 5.1b and hsz70 controller is v77z-2. Console firmware is V6.3.1

    I installed a mirror set in the hsz without any problem. In the system, I tried to use hwmgr -scan scsi to scan in the devices. Although I wont' see anything when running hwmgr -view device yet I can see it in hwmgr -show scis with (null) device file. (see the end of below output with hwid as 145 and scsi device id as 14)

    # hwmgr -show scsi

            SCSI DEVICE DEVICE DRIVER NUM DEVICE FIRST

    While in the console, there is the messages of:

    hwc_check_devnode: block devt (0x05200384) already in use by hwid 79:re-use requested by cdisk for hwid 145
    hwc_check_devnode: char devt (0x05200384) already in use by hwid 79:re-use request by cdisk for hwid 145
    unable to register devnode status= 95

    dsfmgr -k won't help either, and dsfmgr -vV shows everything is fine.

    I suspect that something left from a removed device dsk11 caused the problem and I first used dsfmgr -D dsk11 which didn't work and I deleted all the dsk11 files in /dev/disk and /dev/rdisk but it still won't work.

    Finally, I had to install another mirrored set and it was scanned in without problem, which is dsk44.

    What is the cause of the problem and is there a way to solve it?

    Thanks.
