Thread: AIX & IBM DS4300 disk array

  1. AIX & IBM DS4300 disk array

    Hi All,

    On AIX, DS4300 luns are visible as Disk Array Devices rather than FC
    SCSI Disk Devices.

    root@host # lsdev -C -c disk

    ....

    hdisk129 Available 0A-08-01 1722-600 (600) Disk Array Device

    hdisk130 Available 0A-08-01 1722-600 (600) Disk Array Device

    hdisk131 Available 0A-08-01 1722-600 (600) Disk Array Device

    hdisk132 Available 0A-08-01 1722-600 (600) Disk Array Device

    hdisk133 Available 0A-08-01 1722-600 (600) Disk Array Device





    root@host # /usr/sbin/lsdev -C -c disk -S a -F 'name class subclass
    location parent'

    ......

    hdisk129 disk fdar 0A-08-01 dar0

    hdisk130 disk fdar 0A-08-01 dar0

    hdisk131 disk fdar 0A-08-01 dar0

    hdisk132 disk fdar 0A-08-01 dar0

    hdisk133 disk fdar 0A-08-01 dar0



    Note: hdisk129-133 are IBM Disk Devices.

    Is this a configuration issue? If yes, how can we make sure that
    DS4300 luns are visible as FC SCSI Disk Devices?

    Can i some how change something so that the luns are visible as FC
    SCSI disk devices.

    why would you want to make a properly defined device description
    generic?
