Fujitsu M10 Product Notes page 43

The device path of the I/O device that has been used changes if a CPU memory
■
unit upper (CMUU) is added to add two CPUs when the I/O bus reconfiguration
is enabled in SPARC M10-4 or SPARC M10-4S with two CPUs installed.
As for the ioreconfigure that can be specified by -m function of the setpparmode
(8) command, leave it as the default, false, and disable the I/O bus reconfiguration
function.
If you enable the I/O bus reconfiguration function by specifying true to the
ioreconfigure, it may be necessary to reinstall Oracle Solaris.
With a logical domain running Oracle Solaris 11, updating to XCP 2050 or later
■
allows you to have an increased maximum number of PCIe cards on one root
complex (RC).
To install a PCIe card after updating to XCP 2050 or later, perform the steps below
in the control domain.
This example assumes that two sets of configuration information currently in use,
ldm-set1 and factory-default, are stored.
1. Check the configuration information of the logical domain stored in XSCF.
primary# ldm list-spconfig
ldm-set1 [current]
factory-default
2. Execute the following commands on all of the logical domains, including the
control domain.
Specify the name of the logical domain for ldom.
primary# ldm set-variable fix_atu=true <ldom>
primary# ldm remove-variable fix_atu <ldom>
3. Store the updated configuration information for the logical domain again.
Delete the stored ldm-set1 and then store the information again.
primary# ldm rm-spconfig ldm-set1
primary# ldm add-spconfig ldm-set1
4. Restart all logical domains.
An XSCF user account name cannot be the same as an LDAP user name. In
■
addition, an XSCF user account UID cannot be the same as an LDAP UID.
When starting OpenBoot PROM, even if an error is detected with the GFX 550e
■
graphics card (TechSource, PCIExpress Graphics Board), nothing may be output
to the console.
The problem can be confirmed from the following error log output with the
showlogs error command, which registers the faulty component (suspect
component) as "UNSPECIFIED".
