The service processor provides a range of system management and diagnostic tools that enable you to monitor server operations and troubleshoot server problems. The following is a high-level summary of the various diagnostic tools that are available on the server:
LEDs – Status indicators are provided on the server’s front and rear panels as well as on some FRUs.
ILOM – The Integrated Lights Out Manager (ILOM) firmware runs on the service processor and is the central software resource for identifying and managing problems in the server.
Power-on self-test (POST) – POST performs diagnostics on system components whenever the system is turned on or a system reset is issued.
Solaris OS Predictive Self-Healing (PSH) – PSH continuously monitors the health of the processor and memory, collecting data that can be used to predict component failures before they occur. PSH works with ILOM to take a component offline if data indicate there is a high risk it will fail.
Solaris OS log files and command interface – The Solaris OS reports operational and error information to its standard log files. It also provides various commands for investigating system status.
The LEDs, ILOM, PSH, and many of the log files and console messages are integrated. For example, when the Solaris software detects a fault, it displays the fault, logs it, and passes information to ILOM where it is logged. Depending on the fault, one or more LEDs might also be illuminated.
There are three methods of interacting with the service processor:
ILOM shell (default)
ILOM browser interface (BI)
ALOM CMT compatibility shell
The ILOM shell provides access to ILOM’s features and functions through a command-line interface (CLI). The shell prompt looks like this:
The ILOM browser interface supports the same set of features and functions as the shell, but through windows on a browser interface.
The ALOM CMT compatibility shell emulates the ALOM CMT interface used on earlier generations of CMT servers. The ALOM CMT compatibility shell prompt looks like this:
Note - Unless indicated otherwise, all examples of interaction with the service processor are depicted with ILOM shell commands.
Multiple service processor accounts can be active concurrently. A user can issue ILOM shell commands while logged in under one account and, at the same time, issue ALOM CMT shell commands while operating in another account.
