Workaround: If system fails to boot because of this problem, retry it.
Processor Always Starts on Lowest Available Strand
Regardless If asr Disabled (CR 6541482)
If processor strand 0 of the first available physical core has been marked disabled (as
seen in the list of disabled devices in the output of the showcomponent command
from the sc> prompt), a new master strand is selected by the initialization process,
and the disabled strand is taken offline. But the system initialization and execution
of Power-On-Self-Test (POST) occurs using the disabled processor strand since
power on and resets, execution always starts on strand 0 of the first available
physical core.
When this happens, the system might fail to run the diagnostics and the system
might fail in an unpredictable manner. The system might not start the required
firmware and software components as a result.
Workaround: If strand 0 of the first physical core is known to be good, then it can be
enabled by using the enablecomponent ILOM CLI command followed by power-
on reset of the system (poweroff followed by poweron ILOM CLI commands).
If strand 0 of the first physical core is known to be bad, then there is no workaround.
The entire processor will need to be replaced.
Integrated Lights Out Manager (ILOM) Issues
ILOM is the default service processor (SP) command-line interface (CLI). The default
user is root and the default password is changeme.
ILOM also provides an Advanced Lights Out Management (ALOM) CMT
compatibility CLI. To use the ALOM CMT compatibility CLI, you must first log in to
an ILOM CLI as root and create an admin account with administrator privileges,
and assign alom as the default CLI (cli_mode=alom).
Refer to the Integrated Lights Out Manager 2.0 (ILOM 2.0) Supplement for SPARC
Enterprise T5120 and T5220 Servers and the SPARC Enterprise T5120 and T5220 Servers
Administration Guide for more information on ILOM.
The following are known ILOM CLI and ALOM CMT compatibility CLI (on ILOM)
issues.
