Updating A Basic Input/Output System ('BIOS') Boot Block Security Module In Compute Nodes Of A Multinode Computer |
摘要 |
Updating a BIOS boot block security module in a plurality of compute nodes of a multinode computer including, for each compute node in the multinode computer, upon powering on the compute node: determining whether a new image of security module is available; if a new image of the security module is available, commanding the reset control module of the compute node to block an attempt by the security module to propagate a reset signal on the scalability bus to other compute nodes in the multinode computer; updating to the new image of the security module; upon completion of the update, resetting the compute node including attempting to propagate a reset signal on the scalability bus to other compute nodes in the multinode computer; and blocking the attempt to propagate the reset signal on the salability bus.
