Reboot Many Nodes

How to warm boot many nodes.

When rebooting many CLE nodes, the default is to reboot nodes in chunks up to 96 at a time. To change this chunk size to a different value, the reboot_maxids variable in xtbootsys can be adjusted on the command line for the warm boot command. This example changes reboot_maxids from 96 to 512.

crayadm@smw> xtbootsys --reboot -c reboot_maxids=512
