    you must have seperate FC cards for the fastt. you can not present ESS and
    FASTT LUNs to the same adapters. SDD and RDAC will battle.

    This is probably a simple question but I can't seem to find the answer. Any
    help would be greatly appreciated....

    We have connected an AIX 5.2 ML3 system to our FASTt 600. We defined 3
    LUNS: 20GB, 80GB, and 160GB. When you run cfgmgr it recognizes the 20 and
    80 GB LUNS fine but it has problems with the 160GB. It can't seem to
    configure it and it appears to use a different driver. This machine is also
    connected to an ESS Shark so it does have the 2105 filesets and SDD
    installed as well. We have another server connected to the same FASTt that
    has a bunch of 400GB LUNS that work fine.

    The disks look like this with lsdev -C. hdisk63 is the 160GB LUN.

    hdisk62 Available 10-78-01 1722-600 (600) Disk Array Device
    hdisk63 Defined 00-00-00-00 2102-F10 Disk Array Device
    hdisk64 Available 10-78-01 1722-600 (600) Disk Array Device

    The output that we get when we run cfgmgr is:

    > cfgmgr -i .
    Method error (/etc/methods/cfgfdar -l dar0 ):
            0514-061 Cannot find a child device.
    Method error (/usr/lib/methods/scsimap >> /var/adm/essmap.out):
            0514-023 The specified device does not exist in the
                     customized device configuration database.
