*1 The replacefru(8) command is used for maintenance. For this purpose, select BB in the maintenance menu.
*2 If the XSCFU requiring maintenance is not running, perform active/hot replacement.
*3 If the XSCFU requiring maintenance is not running, perform inactive/hot replacement.
*4 The replacefru(8) command is used for maintenance. For this purpose,
select BB in the maintenance menu.
Alternatively, without using the replacefru(8) command, you can replace a FRU after placing every SPARC
M12-2S in the building block configuration into the cold state.
*5 If the XSCFU requiring maintenance is not running, perform system-stopped/hot replacement. Alternatively,
place every SPARC M12-2S in the building block configuration
into the cold state, and replace the XSCFU.
*6 Maintenance is performed using the SR-IOV function, dynamic reconfiguration function for PCIe devices, and
PCI Hot Plug function.
*7 This is possible only if the target FRU is in a redundant configuration.
*8 This is possible only for the mirror volumes (RAID1 and
RAID1E) when the HDD/SSD used as the boot device
is being replaced.
*9 The FRU can be replaced only when every SPARC M12-2S in the building block configuration is in the cold
state.
*10 The XSCF DUAL control cable or XSCF BB control cable requiring replacement is connected to the XSCFU. If
the
READY LED of the XSCFU is off, place every SPARC M12-2S in the building block configuration into the cold
state, and replace the cable.
