Identifying and troubleshooting firmware issues

Erratic server blade operation, or unsuccessful boot to the UEFI Boot Manager or UEFI Shell, are symptoms of possible firmware issues.

NOTE: Firmware issues are relatively rare. Look for other problem causes first.

Probable firmware failure areas are:

•Unsupported firmware installation

•Corrupt firmware installation

To troubleshoot firmware issues:

1.Verify that all server blade firmware components are from the same release (use the MP sysrev command).

2.Reinstall server blade firmware.

Verify and install the latest firmware

HP recommends that all firmware on all devices in your c-Class Ecosystem be updated to the latest version anytime a new Integrity Server Blade or other hardware component is added.

To verify that you have the latest version of firmware for each component:

1.Go to http://www.hp.com.

2.Locate and click the Support & Drivers link on the main page.

3.Click the button next to Download drivers and software (and firmware).

4.Enter your product name (for example, BL860c i4) or number and click >>.

5.Choose the OS or Cross operating system (BIOS, Firmware, Diagnostics, etc.)

6.Refer to the Release Notes or Installation Instructions to verify the firmware version.

Troubleshooting the server interface (system console)

System console connections using the RS-232 cable are made through the port connectors on the front of the server blade, through the SUV cable. The MP LAN connection can be made via the network or OA.

HP-UX uses the RS-232 serial text connection to a dumb terminal, or to terminal emulator software running on a PC, to control server blade operations locally. All other connections are unsupported.

HP-UX alternatively uses the MP 10/100 BT LAN connection over a private network, to control one or more server blade operations locally through telnet or SSH, or remotely over a public network through a web GUI.

NOTE: RS-232 connection: If a dummy terminal/PC running terminal emulation software is attached to the iLO 3 MP local port and does not respond to a Ctrl–B key sequence then it is possible that the iLO 3 MP is not operational/functional, or the terminal/terminal emulation software is incorrectly configured (wrong baud rate for example).

Troubleshooting the environment

Ambient intake air temperature is often different from ambient room temperature; measure the operating temperature and humidity directly in front of the cabinet cooling air intakes, rather than measure only ambient room conditions.

Temperature sensors are found on:

•System board, where the processors provide an integrated temperature sensor

•Status panel, where a thermal sensor detects the ambient room temperature. This sensor’s reading is the main parameter used to regulate fan speed, under normal conditions.
