Pinned topic Trouble installing RHEL 6.1 on a Power 770

‏2012-03-20T16:32:26Z |
 

The system is a Power770 (12 processors, 46,592 MB RAM, 2 internal drives).
It is currently running AIX 6.1.

The OS was mirrored across both drives. In preparation for installing
RedHat on the system, I removed all LVs from hdisk0 and set the bootlist
to cd0, hdisk1.

I was given a DVD to install - "RHEL 6.1
20110510.1-Server IBM Distrib. for ppc64" according to the label.

Running the console from the HMC, I can boot off the DVD and get to a boot: prompt but I can't get much
further:

md: Waiting for all devices to be available
before autodetect
md: If you don't use raid, use raid=noautodetect
md: Autodetecting RAID arrays.
md: Scanned 0 and added 0 devices.
md: autorun ...
md: ... autorun DONE.
RAMDISK: gzip image found at block 0
RAMDISK: incomplete write (4318 != 32768)
write error
List of all partitions:
No filesystem could mount root, tried: iso9660
Kernel panic - not syncing: VFS: Unable to mount

Any suggestions?

     After attempting several things, I came across this technote: http://www-01.ibm.com/support/docview.wss?uid=isg3T1012911  Althogh it does not mention the P750 or the P770's,  I performed the steps and it seemed to resolve the issue and I was able to install RHEL6.1 on these systems

       Dan, Thanks for posting.  I'm glad to see the that technote solved your problem.  Just so I'm clear, you original had AIX on the devices to which you were installing Linux.  Correct?

     Yes, originally AIX 6.1 was installed on the systems, the customer wanted to keep AIX 6.1 on the second disk, and install RHEL 6.1 on the first disk.   Three more data points, 1) This customer weas moving several P770's to RHEL that were originally install with AIX 6.1, not all required the wipe-nvram.  2) There was yet another customer moving from p750's  & AIX to Linux/RHEL and they hit the same issue which was resolved with the "wipe-nvram" as suggested in the technote. 3) Which is pretty obvious by now, the technote was generated for a PS701, it seems like this issue is not specific to the 701, we are seeing it across a couple of Power platforms. Or, slightly different core issues that the wipe-nvram seems to resolve.

       Thanks, Dan!  We have updated the technote to make it general to any P7 system per your suggestion.

     Hi,
     
    I am having the same issue as Dan. I checked on the link he provided but it's a dead link. I searched technotes but I didn't come across the topic. Do you know if this topic is kept somewhere? 
     
    Thank you,

       Hi Sheryll,
       
      I tried Dan's link, and it resolved for me, so I wonder if there was a temporary glitch. Please try this link: IBM Red Hat 6 p7 install fails
       
      If that also doesn't work for you, send me an email (jessicae@us.ibm.com), and I'll email you a PDF.  
       
      Thanks,
      Jessica Erber-Stark
