Fujitsu M10/SPARC M10 Systems Product Notes for XCP Version 2240 ･ March 2015

Description
If a physical partition (PPAR) is powered
on in the system that satisfies all the
following conditions, other PPAR may
also be powered on.
- The power supply interlocking is
enabled with the setremotepwrmgmt
(8) command.
- A node is created whose SubNodeID is
not set in a power supply interlocking
management item.
- Multiple PPARs are configured.
If XSCF switching or an XSCF reset
occurs while the physical partition
(PPAR) is being powered off, it may be
impossible to turn off the power.
If a hardware failure occurs in a 4BB or
greater configuration, automatic cluster
switching may fail.
If 16 or more guest nodes are incorporated
into a single cluster, the following
warning message may be output to the
console of the control domain.
SA SA_xscf????.so to test host ??? failed
If XSCF switching occurs while multiple
physical partitions (PPARs) are being
powered on at the same time, it may take
more than usual to power them on.
Workaround
- When power supply interlocking is not
necessary
Disable power supply interlocking with
setremotepwrmgmt -c disable and then
delete the power supply interlocking
setting with the clearremotepwrmgmt
(8) command.
- When power supply interlocking is
necessary
If the system has multiple PPARs,
create a management file for power
supply interlocking by specifying a
PPAR-ID as a SubNodeID, and then
register the power supply interlocking
setting with setremotepwrmgmt -c
config.
There is no effective workaround.
While powering off PPAR, do not use the
switchscf(8) command to perform XSCF
switching or the rebootxscf(8) command
to perform an XSCF reset.
If automatic cluster switching fails,
follow the procedure in the manual of the
cluster software to perform switching
manually.
There is no effective workaround.
Do not switch an XSCF by using the
switchscf(8) command while PPARs are
being powered on.
