Sun Blade 6048 Modular System Service Manual

This appendix contains ILOM 2.0 information that is specific to the Sun Blade 6048 modular system.

For additional information on using ILOM with the Sun Blade modular system, see the Sun Integrated Lights Out Manager 2.0 User’s Guide, 820-1188.

The following topics are covered in this appendix:

• Section A.1, Activating CMM Ethernet Ports
• Section A.2, ILOM Behavior With Two Power Cord Configuration
• Section A.3, ILOM Sensor Information

---

A.1 Activating CMM Ethernet Ports

By default, Ethernet Port 0 is enabled on the CMM. You can enable Port 1 or enable both ports through the CLI or the web interface.

Caution - You can cause Ethernet networking problem and bring down the external network if you activate both Ethernet ports on the CMM. Before you activate both ports, make sure the external switch supports trunk mode. The upstream Ethernet switch needs to be configured correctly, so that no Ethernet traffic loop is created. This is done usually by the spanning tree algorithm.

A.1.1 To Enable Ethernet Ports Through the CLI

To enable port 1 via the CLI:

1. Log in to the ILOM CLI:

ssh root@ipaddress

2. Type:

cd /CMM/network.

3. Type show to view the switchconf variable setting.

For example:

show
/CMM/network
    Targets:
 
    Properties:
        commitpending = (Cannot show property)
        ipaddress = 10.6.153.71
        ipdiscovery = dhcp
        ipgateway = 10.6.152.1
        ipnetmask = 255.255.252.0
        macaddress = 00:14:4F:6B:6F:C1
        pendingipaddress = 10.6.153.71
        pendingipdiscovery = dhcp
        pendingipgateway = 10.6.152.1
        pendingipnetmask = 255.255.252.0
        switchconf = port0
 
    Commands:
        cd
        set
        show
 
switchconf = port1

In this example, the switchconf variable is set to port0

• To activate port 1 and disable port 0, type: switchconf=port1
• To activate port 1 and keep port 0 active, type switchconf=trunk

4. Remove the CMM and reinstall it into the chassis.

The active port is now NET MGT port 1 or both NET MGT ports.

A.1.2 To Enable Ethernet Ports Through the Web Interface

To enable an Ethernet port via the web interface:

1. Open a web browser and type the IP address of the server SP or CMM.

The Login page for the ILOM web interface appears.

2. In the ILOM Login page, enter a user name and password then click OK.

The ILOM web interface appears.

3. Click on CMM in the left panel.

4. Click the Configuration tab, then the Network tab.

FIGURE A-1 ILOM Web Interface Network Screen

In the CMM Management Network Switch drop down list, select the port that you want to activate or Trunking (Link Aggregation) to activate both ports.

5. Remove the CMM and reinstall it into the chassis.

The active port is now NET MGT port 1 or both NET MGT ports.

A.2 ILOM Behavior With Two Power Cord Configuration

This section specifies how CMM and server module firmware behave when only two of the three power plugs are connected to an A231 power supply module.

There are three plugs on the back of each A231 PSU. These plugs are named AC0, AC1, and AC2. Each allow connection of a 220V power cord.When only two of the available three plugs is connected to the A231 PSUs, this will provide 5600 watts to the entire chassis.

If you connect only two of the total three plugs, connect them to AC0 and AC1. AC2 should not be connected.

For details on ILOM, refer to the Sun Integrated Lights Out Manager 2.0 User’s Guide.

A.3 ILOM Sensor Information

The chassis includes a number of sensors that generate entries in the system event log (SEL) when the sensor crosses a threshold. Many of these readings are used to adjust the fan speeds and perform other actions, such as illuminating LEDs and powering off the chassis.

These sensors can also be configured to generate IPMI PET traps as, described in the Integrated Lights Out Manager (ILOM) Administration Guide 820-0280.

Caution - Do not use any interface other than the ILOM CLI or web GUI to alter the state or configuration of any sensor or LED. Doing so could void your warranty.

A.3.1 Basic Status Sensors

nemn.prsnt

These sensors report whether the network express modules (NEMs) are present. NEMs are numbered from 0.

A.3.2 Power Supply Sensors

There are two power supplies in the chassis. Each power supply has two AC input lines and two DC output lines. All are numbered from 0.

psn.prsnt

Reports the presence of the power supply.

psn.vinokn

Reports the status of the AC input lines for each power supply.

psn.pwrokn

Reports status of DC output lines for each power supply.

A.3.3 Fan Sensors

The chassis contains eight fan modules. Each module contains two fans. Modules and fans are numbered from 0.

fmn.fn.speed

These sensors report individual fan speeds. All fan speed sensors are configured to generate the same events and all faults are handled in the same way. They are not monitored when the chassis is powered off.

fmn.fail

These sensors report fan module failure status.

A.3.4 Server Module Present

bln.prsnt

These sensors report whether server modules are present in the specified slots. Slots are numbered from 0.

A.3.5 Chassis Sensors

ch.t_ovrd

This sensor reports if any blade is requesting full fan speed due to high temperature.

ch.t_amb_n

Two sensors, ch.t_am_0 and ch.t_amb_1, report ambient temperature in the chassis midplane. These are for monitoring only; no threshold is defined.

ch.pwrctl.state

Reports power supply oversubscription state.

.

A.3.6 Readings for Specific Cases

This section shows some of the sensor readings for the SEL in cases that are specific to the Sun Blade 6048 modular system.

A.3.6.1 CMM Boots

When the CMM boots up, the SEL displays the readings shown in TABLE A-3.

A.3.6.2 AC Cables Are Disconnected

When three of the AC cables get disconnected, the SEL displays the readings shown in TABLE A-4.

A.3.6.3 All the AC Cables Get Disconnected, Then Plugged Back In

When all of the AC cables get disconnected, then plugged back in the SEL displays the readings shown in TABLE A-5.

A.3.6.4 Stop /CH

When the stop /CH command is applied, the SEL displays the readings shown in TABLE A-6 .

A.3.6.5 Start /CH

When the start /CH command is applied, the SEL displays the readings shown in TABLE A-7.

A.3.6.6 One PSU Is Removed

When one PSU is removed, and there is too much power consumption in the chassis to support PSU redundancy, the SEL displays the readings shown in TABLE A-8.

A.3.6.7 PSU Is Re-inserted

TABLE A-9 shows the SEL readings as a PSU is reinserted into the system and the system recognized that power has been re-applied.
