In addition there are two system LEDs labeled Source A and Source B. These show
the state of the power feeds to the server. The four physical power feeds are split
into A and B, two feeds for each source.
Feed A supplies PS0 and PS1, feed B supplies PS2 and PS3. If either PS0 or PS1
receives input power then the Source A indicator is lit. If either PS2 or PS3 receives
input power then the Source B indicator is lit. If neither of the supplies receives
input power, the indicator is turned off.
These indicators monitor the system periodically, at least once every 10 seconds.
CPU/Memory Troubleshooting
This section discusses common types of failure:
■
Unconfigure operation failure
■
Configure operation failure
The following are examples of
cfgadm
diagnostic messages.
See the following man pages for additional error message detail –
cfgadm
(1M),
cfgadm_sbd
(1M), and
config_admin
(3X).
CPU/Memory Board Unconfiguration Failures
An unconfigure operation for a CPU/memory board can fail if the system is not in a
correct state before you begin the operation:
■
Memory on a board is interleaved across boards before an attempt to unconfigure
the board.
■
A process is bound to a CPU before an attempt to unconfigure the CPU.
■
Memory remains configured on a system board before you attempt a CPU
unconfigure operation on that board.
