    I'm having a few problems, the first is the "NO operating system installed" when trying to boot from an iso image. I have created a VIO server with an iso repository:
    lsrep
    Size(mb) Free(mb) Parent Pool Parent Size Parent Free
    20397 15298 rootvg 571392 353280

    Name File Size Optical Access
    AIX6_DVD1 3786 vtopt1 ro
    AIX6_DVD2 1313 None ro

    I have loaded the AIX6_DVD1 into the drive which is mapped to a virtual scsi device:
    SVSA Physloc Client Partition ID
    --------------------------------------------
    vhost5 U8203.E4A.061B985-V2-C41 0x00000000

    VTD vtopt1
    Status Available
    LUN 0x8100000000000000
    Backing device /var/vio/VMLibrary/AIX6_DVD1
    Physloc

    I then add this to my lpar however when I try and boot I get "No Operating System Installed"

    The second weird problem is that I the lpar only ever seems to be able to see two boot devices when I do list all devices. For example when booting with two logical disks, the virtual cd drive and virtual Ethernet I get:

    1. 1 PORT - 2 IBM Host Ethernet Adapter
    ( loc=U789C.001.DQD2J21-P1-C7-T2 )
    2. - SCSI CD-ROM
    ( loc=U8203.E4A.061B985-V1-C4-T1-L8100000000000000 )
    However if I remove the Ethernet device from the configuration I get:

    1. - SCSI 279 GB Harddisk
    ( loc=U8203.E4A.061B985-V1-C2-T1-L8100000000000000 )
    2. - SCSI CD-ROM
    ( loc=U8203.E4A.061B985-V1-C4-T1-L8100000000000000 )

    Can you try loopmount on the .iso to get it online in the VIOS and check it looks like a valid filesystem inside?

    The boot prom loader can't find the boot files and so says it is not a valid boot image.

    Second bet would be checking you have the latest VIOS levels and ALL the service packs for it. And third have you got the latest firmarw on the machine.

    Not real clue on the two boot devices but it "smells" like firmware to me.

    I use the virtual DVD all the time to install beta levels of AIX as NIM does not like it and I have had the DVD image damage problems in the past but not the other issues.

    best of luck, Nigel
