ODA: Are there any circumstances where only one server node is rebooted after applying a patch?
By uwes on Dec 07, 2011
It depends on the patch. One or both nodes could be rebooted.
A reboot (either one or both node) will not accor every time a patch is applied.
A reboot will accor when the OS, the ILOM or storage firmware need to be patsched, patching other components doesn't require a reboot.
It's possible to reboot one node when we patch shared storage components (SSDs and Shared HDDs).
The readme file of the patch will provide the infromation if the patch requires a reboot. In future there will be a message printed on the screen to inform the customer and ask for confirmation.
