    260260 5. Create images for compute nodes with different architectures. Turns out we also have a couple of PE 2950. After updating BIOS to latest, rsetboot boot works as expected. However, since it has an architecture different from the head node (PE 860), the image has to be created differently. Most importantly the PE 2950 does not use tg3 driver for ethernet interfaces. To create the image, run: 
    261261 {{{ 
    262  #genimage -i eth0 -n tg3,bnx2 -o centos5.5 -p compute 
     262 #genimage -i eth0 -n bnx2 -o centos5.5 -p compute 
    263263 }}} 
    264264 Then, follow the rest instructions. Notice that in our case the compute node (2950) and the head node (860) are somewhat similar. For a more general case that the architectures are significantly different, you should mount /install in head node to the compute node (on your head node, /install should already be exported -- see /etc/exports), then generate the image on the compute node (refer to genimage manpage for details).
