Notes On The Logical Domain Time - Fujitsu M10 Product Notes

Notes on the logical domain time

Suppose the physical partition (PPAR) has been kept active for a long time on the
system with the XCP version earlier than XCP 2232. Then restarting the physical
partition may cause the Oracle Solaris time to deviate. This problem (RTIF2-140711-
001) is solved in XCP 2240 and later XCP versions. However, restarting a physical
partition right after firmware update from XCP 2232 or earlier to XCP 2240 or later
may cause the Oracle Solaris time to deviate.
Also, after the physical partition (PPAR) has been kept active for a long time,
restarting the physical partition may cause the time of logical domains other than the
control domain to deviate. (RTIF2-141204-001)
To solve these problems, restart the physical partition, boot Oracle Solaris in
single-user mode, execute the date(1M) command, and then set the correct time.
The following shows the workaround procedure.
1.
Execute the poweroff -p command to power off the target physical partition.
Also, stop the logical domains within the physical partition.
XSCF> poweroff -p xx
PPAR-IDs to power off: xx
Continue? [y|n] :y
xx : Powering off
*Note*
This command only issues the instruction to power-off.
The result of the instruction can be checked by the "showlogs power".
XSCF>
2.
Execute the showpparstatus(8) command to confirm the physical partition is
powered off. Confirm the PPAR Status displays "Powered off."
XSCF> showpparstatus -p xx
PPAR-ID PPAR Status
00 Powered off
3.
Execute the showdate(8) command to display the clock time of XSCF.
XSCF> showdate
Mon Jan 23 14:53:00 JST 2012
Note - Set the clock to the right time if it is incorrect. Power off all physical partitions if you
set the time by executing the setdate command.
Starting the physical partition may cause the logical domain time to deviate. Use the
NTP server to set the logical domain time, or, if it is the control domain, perform
steps 4 to 9 in the following procedure, execute the date(1M) command in single-user
mode, and set the control domain time.
