  • The 'addhost' command is executed from the HPC installer node and the compute nodes are booted up for the PXE installation. The compute node boots up properly but tracebacks with the above messages when starting the installation.

  • The problem is happening on the IBM x3650 M1 machines. The firmware is updated, but it didn't help.


  • Red Hat Enterprise Linux 5.5 HPC Installer node.

  • IBM x3650 M1 and IBM x3650 M2 machines.

  • IBM ServeRAID RAID array configured for RAID 1 connected as Serial Attached SCSI (SAS).

  • Cisco 2960G switches on a class C network with IP range 192.168.88/24
