    Garbage When Trying to Load ALOM Runtime Image

    836242
      Hi All,

      We think we have ruined the image that comes with the SC or something but we were trying to install Debian Linux on this V240. On the OBP we typed

      ok boot new linux root=/dev/nfs nfsroot=10.1.3.1:/mnt/iso ip=10.1.3.11:10.1.3.1:10.1.3.254:255.255.255.0:SWITCH01

      Where:
      /mnt/iso is where we mounted the Debian ISO via lofiadm
      10.1.3.11 is the IP we wanted to assign this machine
      etc.

      After it went through this, we got a lot of garbage on the screen. So we recycled power (Cold reboot) the machine and now this happens:


      ALOM BOOTMON v1.5.1
      ALOM Build Release: 001

      Please help! We're actually not physically at the server and it's sitting 10,000 miles away. We have access to remote power boot and a serial access into the machine however.

      Thank you in advance

          Just FYI, This has been resolved

          This was caused by a mismatch in the baud rates of the console server connected to the Serial port of the machine, where a colleague had changed
          ttya-mode to 19200,8,n,1,- while the console server was still configured for 9600.

          Please note that the speed / baud compatibility changes between steps during the boot process. That is, the baud required before the point of

          Loading the runtime image...

          showed all messages properly @ 9600

          Right after that message, it was required we change it to 19200, to be able to see all messages

          After getting into ALOM, and issuing a command like 'poweron', we got all garbage again, till we changed the baud back to 9600

          and once booted into OBP, the baud needed to be changed back up to 19200.

          VERY weird!

          Anyway, everything's been set back to 9600 to avoid this in the future.
