CHAPTER 7 Hot Swapping
(7) PCI cards
Hot swapping is available. A redundant configuration is also available using
mirroring software (such as PRIMECLUSTER GDS).
Hot swapping is available while a PCI card is cassette inserted in a PCI cassette.
(8) BPs
Redundant configuration is not adopted, and hot swapping is not available.
(9) XAIs
A redundant configuration and hot swapping are available while System Mirror is
enabled. They are not available when System Mirror is not enabled.
When operation is performed in System Mirror:
Two XAI systems form a redundant configuration. If an XAI fails, the failed XAI is
automatically isolated from the system operation configuration and operation
continues with the other normal XAI in degradation mode without a reboot. The
failed XAI thus isolated can be hot-swapped. To incorporate a new XAI into the
system, all the partitions must be restarted.
When operation is performed without System Mirror:
An XAI does not form a redundant configuration. If the XAI fails, all partitions stop.
The failed XAI can be maintained (swapped) while all the partitions are stopped. A
new XAI after swapping is automatically incorporated into the system when any
partition is started.
