Manually Boot the Compute Nodes

All service and login nodes are booted and Lustre, if configured at this time, has started.
  1. Invoke the xtbootsys command if it is not running.
    crayadm@smw> xtbootsys
    Enter your boot choice:
       0) boot bootnode ...
       1) boot sdb ...
       2) boot compute ...
       3) boot service ...
       4) boot all (not supported) ...
       5) boot all_comp ...
       10) boot bootnode and wait ...
       11) boot sdb and wait ...
       12) boot compute and wait ...
       13) boot service and wait ...
       14) boot all and wait (not supported) ...
       15) boot all_comp and wait ...
       17) boot using a loadfile ...
       18) turn console flood control off ...
       19) turn console flood control on ...
       20) spawn off the network link recovery daemon (xtnlrd)...
       q) quit.
  2. Select option 17 (boot using a loadfile). A series of prompts are displayed. Type the responses indicated in the following example. For the component list prompt, type p0 to boot the entire system, or pN (where N is the partition number) to boot a partition. At the final three prompts, press the Enter key.
    Enter your boot choice: 17
Enter a boot type string (or nothing to do nothing): CNL0
Enter a boot type option (or nothing to do nothing): compute
Enter a component list (or nothing to do nothing): p0
Enter 'any' to wait for any console output,
   or 'linux' to wait for a linux style boot,
   or anything else (or nothing) to not wait at all: Enter
Enter an alternative CPIO archive name (or nothing): Enter
Do you want to send the ec_boot event ('no' means to only load memory) ? [Yn] Enter
  3. Return to the xtbootsys menu after all compute nodes are booted. Type q to exit the xtbootsys program.
  4. Remove the /etc/nologin file from all service nodes to permit a non-root account to log on.
    smw# ssh root@boot
boot# xtunspec -r /rr/current -d /etc/nologin
