n
For details, refer to
This function automatically disconnects a failed SB, incorporates a spare SB that has
been configured in advance, and starts PPAR to continue system operation.

Degradation Function

n
If redundantly configured hardware fails, this function isolates the failed component
and configures the system with the remaining hardware resources to continue system
operation.
Dynamic Reconfiguration [2400E/2800E Only]
n
Dynamic Reconfiguration links with RHEL to enable the addition or the removal of
hardware resources such as CPUs, memory, and I/O in a partition without stopping the
PPAR system.
Resources are added or removed in units of SBs or IOUs with the PCI Box LH modules.
* Dynamic Reconfiguration as a hardware and firmware function of PRIMEQUEST
supports online removal of SBs. However, as of when this manual is published, no
OS vendor states availability of this function.
