You cannot replace the master XSCFU. To replace it, switch the master, or remove
the power cords of all the BBs.
■
If you select the XSCFU in the replacefru command menu, you cannot remove the
XSCF DUAL control cable, XSCF BB control cable, or power cord. The only unit
that you can remove is the XSCFU.
■
During the XSCFU replacement, do not configure the various settings of XSCF
reboot, master switching, firmware update, physical partition power-on/power-
off/reset, and the XSCF. If any of these processes is in progress, wait for the
process to complete before replacing the XSCFU.
■
During the active replacement of the XSCFU, the ldm command may cause an
error in the control domain where the replacement is performed. Retry after the
replacement of the XSCFU is complete. After the replacement is complete, check
that the ldmd service in the control domain is running normally.
Precautions for CMU and memory replacement
■
When remounting memory during the replacement of the CMUL/CMUU or
memory, be sure to remount a memory module of the same capacity and the same
rank at the same location as before.
■
If you have replaced the CMUL that has the hardware RAID function enabled,
re-enable the hardware RAID volume.
For details, see "14.2.11 Re-enabling a Hardware RAID Volume" in the Fujitsu
SPARC M12 and Fujitsu M10/SPARC M10 System Operation and Administration
Guide.
