Notes On Maintenance For Cpu Memory Units, Motherboard Unit, Xscf Unit, Psu Backplane, Or Crossbar Backplane Unit - Fujitsu M10 Product Notes

device aliases disk and net by using the OpenBoot PROM nvalias command.
From XCP 2210 onwards, at the time of starting up OpenBoot PROM, the
■
following message is output to the domain console before the OpenBoot PROM
banner is displayed.
NOTICE: Entering OpenBoot.
NOTICE: Fetching Guest MD from HV.
NOTICE: Starting additional cpus.
NOTICE: Initializing LDC services.
NOTICE: Probing PCI devices.
NOTICE: Finished PCI probing.
Suppose the following: The environment variable multipath-boot? of OpenBoot
■
PROM is true; the boot -L command is executed to display boot environments
(BEs) that, existing in the root pool, allow booting; and the number of a boot
environment is selected from the displayed interactive menu. The system does not
return to the ok prompt, but restarts OpenBoot PROM.
The number of restarts depends on the environment variable boot-device of
OpenBoot PROM. OpenBoot PROM restarts as many times as the number of
configured devices and then the message "ERROR: All device paths in boot-device
have failed." is displayed and the ok prompt reappears.
To avoid this problem, set the environment variable multipath-boot? of OpenBoot
PROM to false before executing the boot -L command or execute the boot
device_path -L command.
Notes on maintenance for CPU memory units,
motherboard unit, XSCF unit, PSU backplane, or
crossbar backplane unit
[SPARC M10-1/SPARC M10-4S]
■
When replacing a motherboard unit or a PSU backplane, mounted on SPARC
M10-1 or when replacing an XSCF unit or a crossbar backplane unit, mounted on a
crossbar box, if any of the following conditions are true, execute the following
procedures to solve the problems reported in RTIF2-130806-001, which has been
fixed in XCP 2220.
<Condition 1>
XCP firmware version is XCP 2210 or older.
<Condition 2>
The microSD card of the old motherboard unit or the old XSCF unit is not used.
* As XSCF firmware writes onto the microSD card, mounted on the FRUs, if the
XSCF firmware is XCP 2210 or older, the following procedure is necessary
because failing to do so will result in the occurrence of the problem reported in
RTIF2-130806-001.
- If the setting specifying the XSCF as an NTP client is disabled:
