* The term CPU, in this text refers to the processor and not to specific CPU cores.
Following are two examples of how different partition changes impact system settings.
If partitions are changed from AAAA to AACC
For partition A: None of the system settings will be changed. Error logs will be cleared on blade
1 and 2.
For partition C: All system settings should be set to the following factory default values:
•
Hyper threading = ON
•
Memory interleaving = MostlyNUMA
•
All CPUs and DIMMs are active on all the blades in the new partition
•
Error logs will be cleared
•
UEFI variables will be set to factory default values
If partitions are changed from AACC to AAAA
For partition A:
•
Hyper threading, memory interleaving and UEFI variables settings should not change.
•
Previously deconfigured CPUs and DIMMs on blade 1 and 2 will remain deconfigured.
Previously deconfigured CPUs and DIMMs on blade 3 and 4 will be active.
•
Error logs will be cleared on all blades.
Boot options for Partition use cases
For the creation of a new partition, the boot path and boot image creation must be treated the
same as installing a new factory fresh Integrity bladed server. For cases of growing the partition
resources by partitioning, the existing HP-UX installed image being used, prior to scaling up, will
discover newly added blade physical processor, memory, and I/O resources. Note that online
addition of resources is not supported.
NOTE:
If resources are being added into the partition and your operating system is not configured
for them, the administrator may need to update or reconfigure the HP-UX operating system. An
example would be a new type of I/O device requiring a new I/O driver.
