Pinned topic Booting PowerLinux Toolkit 5.3 and RHEL 6.3 ISO from the same VM Library & Errors

‏2013-02-01T20:36:26Z |
. VM LIbrary is created on VIO and both PowerLinux Toolkit and RHEL iso is copied into the dir 
. single VIO serving 2 vSCSI devices toa single LPAR
. 2 Virtual Optical devices are created and bound to each of the vSCSI hosts above (vhost2 and vhost3)  
. PowerLinux ISO is presented to LPAR on vhost2
. RHEL ISO is presented to LPAR on vhost3 
. booting to the Toolkit works from LPAR SMS menu ... resulting in the boot: prompt 
. issuing "boot: linux" (hoping to boot the 2ndary device RHEL ISO) results in the following errors below 
. is there a easier way to do this? 
 
Advise, Thanks! 
Dan

     Dear Dan,
    Two vhosts might be complicate for Powerlinux toolkit. It might be getting confused which one to be choosed and usually lack of that intelligence to select automatically  
    There is a simple way to do installation using PowerLinux toolkit .
    Instead of two Vhosts scsi attached to the same lpar, attach only one Vhost scsi (or DVD rom).
    Then attach Powerlinux toolkit first and boot the system with it.
    Once installation gets started , it will ask to attach RHEL6.3 distro dvd , then remove the Powerlinux toolkit from the DVD rom , and attach RHEL6.3 to it.
    And now you can proceed for the installation , after installation gets finished , it will ask for Powerlinux toolkit again for the last time.
    This will help to configure post installation stuffs & your system would be ready to use.
     
    Thanks...
    Manas

      so my error does match your URL above ... and I tweak the real-base size to 1000000 then reset-all ... 
       
      I am attempting to boot the IBM PowerLinux Toolkit 5.3 ...  
       
      Now the error is a reboot loop which says this ... this is on a LPAR provisioned with a Client SCSI Virtual Optical Device via the VIO VM Library facility

        This is with PowerLinux Toolkit 5.3 ... at the boot prompt I gave it
        Trying to boot the toolkit to an LPAR, so I can install Linux (RHEL 6.x) to it 
        Toolkit presented via a Virtual Optical Device on the backing VIO
        VIO @ 2.2.0.10-FP-24
         
        boot: linux debug rdinitdebug 
         
        And captured the following ... is the Toolkit just not finding the Virtual Optical Device, is this a logic issue? Toolkit issue? or VIO f/w issue?

           Are you still using two separate vHosts for each virtual optical drives? That's neither necessary or recommended, really.
           Usually, you just need one vHost adapter per client, and then you can attach multiple client vscsi devices to that, similar to how a real scsi chain would work.
           
          It seems you are having issues with IBMIT, however. Have you tried just booting the RHEL media and installing that way?
          Use the VNC graphical install option. (just issue "linux vnc"at the boot prompt and away you go)

             I'm back down to 1 vhost provisioning the single Virtual Optical drive ... but discovered by issue was a dual pathed vFC device presented to the lpar which was causing it to choke. When I reduced this vFC device to a single path ... I got further.
             
            I could not boot direct to the RHEL media via the Virtual Optical drive ... it kept saving No Software Found.
