Preparing for Enhanced Processor Drawer Availability

Edit online

This option determines the readiness of the system for the targeted processor drawer. The configured processors and the in-use memory are evaluated for evacuation from the targeted processor drawer to the unused resources available on the remaining processor drawers within the system configuration. In addition, the I/O connections associated with the targeted processor drawers are analyzed for any Single Path I/O connectivity.

There are three states which can result from the prepare option:

The system is ready to perform the Enhanced Processor Drawer Availability for the targeted processor drawer with the original configuration.
The system is not ready to perform the Enhanced Processor Drawer Availability due to conditions noted from the prepare step. See Getting the system ready to perform Enhanced Processor Drawer Availability for more details.
The system is ready to perform the Enhanced Processor Drawer Availability for the targeted processor drawer. However, processors were reassigned from the original configuration in order to continue. Reassigning non-dedicated processors for details.
