Fujitsu M10-4 - Inactive Maintenance

*1 The unit is mounted only in the SPARC M10-4S.
*2 The cable is mounted only in a building block configuration using the SPARC M10-4S.
*3 This is enabled only if the target FRU is in a redundant configuration. For the redundant configuration, we recommend active/hot
maintenance that has a short work
time.
*4 If the target internal disk is the boot device, you cannot use this form of maintenance when the configuration is not a redundant
configuration (RAID configuration). If it is not the boot device, or if even the boot device is redundantly configured, we recommend
active/hot maintenance that has a short
work time.
*5 Perform maintenance work using PCI Hot Plug (PHP). When combined with dynamic SR-IOV and the dynamic reconfiguration
function of PCIe end point devices, PHP enables active maintenance of PCIe cards for which the SR-IOV virtual function and PCIe end
points are assigned to I/O domains.
*6 All FRUs are subject
to this maintenance. It is necessary to use dynamic reconfiguration (DR) to disconnect the chassis requiring
maintenance from the physical partition.

3.3 Inactive Maintenance
The type of maintenance performed with the physical partition stopped--the one to
which the chassis requiring maintenance belongs--is referred to as inactive
maintenance. You can perform inactive maintenance only for a system that uses the
SPARC M10-4S in a building block configuration.
Table 3-3 shows whether inactive maintenance is enabled for
each FRU.
