Platform Manage Troubleshooting Tips

Note: The DEL key and F2 key work only if the proper ACSII terminal settings are in place.
Many Linux distributions default to varied ASCII settings. In the case of the SGI
Altix XE340 or

for more specific information about BIOS settings on the head or compute nodes.

This command must be run on the head node. If this does not change Platform’s state, then you
should reboot the head node. This should ensure that Platform will be in a consistent state. If you
