ILOM on the CMM

ILOM on the Chassis Monitoring Module (CMM) provides minimal information for Multi-Fabric NEMs.

The ILOM web GUI recognizes the presence of Multi-Fabric NEMs but does not interact with them.

The ILOM CLI can also get FRU and SEEPROM information from Multi-Fabric NEMs, but does not provide any diagnostic information.

ILOM generates logs that record if a Multi-Fabric NEM is inserted, removed, powered up, or powered down.

A log entry is also generated if the Service LED turns on or off. The Service LED is turned on for an over-temperature or over-voltage condition.

Note - A sudden over-voltage or over-temperature surge powers off the Multi-Fabric NEM. When such a module powers off, the Service LED is turned off also. The service condition is recorded in the log, however.

To see the CMM log for the Multi-Fabric NEMs (as well as any disk blades or server blades present), run this command from the CMM CLI:

-> show /CMM/logs/event/list

If you want to monitor and interact with Multi-Fabric NEMs, you must use a special ILOM proxy program.

ILOM 2.0 Proxy CLI Program For SAS-NEMs and Disk Modules

You can use a proxy program in the Sun Integrated Lights Out Manager (ILOM), version 2.0.3.10 or higher on the chassis CMM to monitor and control your Multi-Fabric NEMs.

Note - There is no proxy CLI for ILOM 3.0.

Only the ILOM command-line interface (CLI) is available for use with the proxy program. You can connect to the ILOM CLI by either of two means:

Connect a terminal or PC running a terminal emulator directly to the CMM serial port on your chassis.

Connect to the Ethernet network management port using a secure shell (SSH).

Instructions for setting up and using ILOM are documented in the Sun Integrated Lights Out Manager 2.0 User’s Guide, available at:

http://docs.sun.com/app/docs/doc/820-1188

To Start the ILOM 2.0 Proxy CLI Program

Prerequisite: To start the proxy CLI, a SAS-NEM module must be installed in the chassis in either NEM slot.

1. Connect to the ILOM CLI and then start the proxy CLI with one of the following commands:

-> start /CH/NEM0/SAS/cli
-> start /CH/NEM1/SAS/cli

Note - The proxy CLI commands are case-sensitive.

When you start the proxy CLI, you see a list of all the SAS-NEMs and disk blades in the system. For example:

-> start /CH/NEM0/SAS/cli
Are you sure you want to start /CH/NEM0/SAS/cli (y/n)? y
Found SAS-NEM in NEM slot 0
Found SAS-NEM in NEM slot 1
Found STORAGE in BL slot 1
Found STORAGE in BL slot 3
Found STORAGE in BL slot 7
Welcome to proxy CLI on slot 0
proxy ->

There are two NEM slots, 0 and 1, and there are 10 slots for blades like the disk module, 0 through 9. The SAS-NEMs in the chassis are referred to as NEM0 and NEM1, while the disk blades are referred to as BL0, BL1, ... BL9.

Note - Server modules in the chassis are not detected by the proxy CLI program.

Navigation Using the CMM ILOM CLI

With the CMM ILOM CLI (either with the proxy CLI for ILOM 2.0, or the standard CLI with ILOM 3.0), you navigate through a tree consisting of all the SAS-NEMs and disk modules (called targets) in the chassis. You can use standard Linux and Unix commands such as cd or pwd to navigate through the tree.

The tree consists of all the SAS-NEMs and disk blades in the chassis.

FIGURE 3-1 The Proxy CLI Tree of Targets

Figure showing the proxy CLI tree of targets.

You can use these commands to navigate through the tree:

show (with no argument): Shows contents of the current target. Lists targets directly beneath the current target, properties of the current target, and available proxy commands.

show (with argument): Shows contents of the target specified. For example, show BL3

cd (with argument): Changes current target to that of the target specified. For example, cd NEM1 or cd ../NEM1

pwd (with no argument): Determines where you are in the tree of targets (because the prompt doesn’t tell you).

cd /: Returns to the root of the tree of targets.

You can use these commands on module targets (NEMx and BLx):

start: Powers on the current target or the given target.

stop: Powers off the current target or the given target.

reset: Powers off, then powers on the current target or the given target.

Caution - The resetand stopcommands do not check for host activity. You should only use these commands if you are sure that the device is not in use.

You can use this command on property targets:

set: Changes the value of the specified property to the given value.

You can use these commands at any time:

exit: Leaves the proxy CLI and return to the ILOM CLI.

help: Shows the help screen.

version: Shows the current versions of the proxy program and the AMI MG9073 firmware on each disk blade.

load: Loads new AMI MG9073 firmware.

CMM ILOM Management and Monitoring for SAS-NEMs and Disk Modules

The CMM ILOM CLI (ILOM 2.0 or 3.0) allows you to do the following:

View and Navigate NEM and Sun Blade 6000 Disk Module chassis locations.

View the values of the Locate and Service LEDs on the Sun Blade 6000 Disk Modules and SAS-NEMs. The Power and Service LEDs are both under control of the expander firmware running on the disk blade or SAS-NEM. You can view these LEDs from the CLI program, but you cannot change them directly.

View IPMI sensor state values for the SAS-NEMs and Sun Blade 6000 Disk Modules.

Stop and start the SAS-NEM or disk module by using the stop and start commands. You can achieve the same result by setting the power_state property to off or on: for example, set power_state=off.

Reset the SAS-NEM or disk module.

Light the Locate LED. The CMM ILOM CLI controls only one LED directly. You can turn the Locate LED on (value=fast blink) or off (value=off). ILOM will turn off the Locate LED after a specified timeout (default = 30 minutes).

View and load new AMI MG9073s firmware to Sun Blade 6000 Disk Modules.

What You Can Set or Change in the Proxy Program

This CLI allows you to set or change the following:

Stop and start the SAS-NEM or disk module by using the stop and start commands. You can achieve the same result by setting the power_state property to off or on: for example, set power_state=off.

Reset the SAS-NEM or disk module.

Turn the Locate LED on or off.

View and load new AMI MG9073 firmware to Sun Blade 6000 Disk Modules.

Upgrading CMM ILOM Firmware

ILOM 2.0.3.10, build 36968 for the Sun Blade 6000 System chassis is the minimum version required for use with disk blades and SAS-NEMs. This firmware can be downloaded from:

http://www.sun.com/servers/blades/downloads.jsp#6000dm

You can upgrade your ILOM firmware in two ways: by using the CLI or by using the ILOM web interface.

To Upgrade ILOM Firmware Using the CLI

Use a tftp server:

1. Put the .ima file in the /tftpboot directory.

2. In the CLI, run this command:

-> load -source tftp://<IPadd>/ilom.6000-2.0.3.10-r36968.ima

where IPadd is the IP address of your tftp server.

To Upgrade ILOM Firmware Using the ILOM Web Interface

1. Log in as any user with Administrator privileges.

2. Select Maintenance --> Firmware Upgrade.

The Firmware Upgrade page appears.

3. Click Enter Upgrade Mode.

A dialog box appears asking you to confirm that you want to enter Upgrade mode.

4. Click OK to enter Upgrade mode.

ILOM stops its normal operation and prepares for a flash upgrade.

5. Enter the path to the new ILOM .ima file in the Select Image File to Upload field or click Browse to locate and select the .ima file.

6. Click Upload.

After a short pause, a Firmware Verification screen appears that shows the current firmware version and the requested upgrade version.

7. Click Start Upgrade.

The process takes about 6 minutes. At the end, the service processor is reset.
