CHAPTER 7 Applicable Components for Hot Maintenance

7.1 Overview of Hot Maintenance

CHAPTER 7
This section describes the hot maintenance of hardware components.
7.1 Overview of Hot Maintenance
Hot maintenance is a maintenance which is carried out on components wherein the status has changed from
running to stopped due to a failure while the system is running, without stopping the partition which is
operating. Components for which maintenance is completed can be reincorporated into the running system.
The term 'hot maintenance' does not apply only to replacing a component whose status has changed from
running to stopped because of a failure, without stopping the partition. It also includes the work of
intentionally removing components from operation in the system and adding components for expansion
purposes without stopping the partition.
As a general rule, a field engineer carries out the hot maintenance. For details on the components to which
hot maintenance can be applied and the redundant configurations, see 'Chapter 3 Component Configuration
and Replacement (Addition and Removal) in the "PRIMEQUEST 2000 Series Administration Manual" (C122-
E175EN).

List of Components

This section describes the components to which hot maintenance can be applied. For details on each
component, see 'Chapter 3 Component configuration and replacement (expansion, removal) of the
"PRIMEQUEST 2000 Series Administration Manual" (C122-E175EN).
- PSU
A PSU alone can be replaced while the system continues running. Replacement of a PSU in a non-
redundant configuration requires the system to be stopped.
- Fan
A fan alone can be replaced while the system continues running.
-
SB
An SB can be replaced while the partition to be maintained is powered off.
The DIMM, CPU, BATTERY, Mezzanine Board and SAS RAID controller card that are mounted on SB
can be replaced individually by physically removing the SB.
-
IOU
An IOU can be replaced when all the partitions, to which the IOU to be maintained belongs, is switched
off. With the Dynamic Reconfiguration function, even an IOU that is incorporated into the partition can be
replaced while the system continues running.
-
HDD / SSD
An HDD / SSD alone can be replaced without removing the disk unit.
-
DU
The DU can be replaced when the partition for maintenance is switched off. The SAS card alone can be
replaced by removing the unit.
-
MMB
Hot replacement is possible while the system is running, when two MMBs are mounted As a standard,
as the faulty MMB is swapped with the Standby MMB, the faulty MMB (Standby MMB) can be replaced
as such. To replace an active MMB, maintenance replacement is done after swapping with the Standby
MMB. It does not affect the control / monitoring in the system.
- PCI Express Card of PCI _Box
The PCI Express card of the PCI_Box can be replaced while the system is running only when the
OS/Hypervisor is supported.
