New Features and Support
This software release contains the following enhancements:
Note - RHEL5 Customers: Some RHEL5 drivers are not available. For details, see "Invalid Cross-Reference Format".
SIA installs a set of Sun-supported drivers that have been tested for quality assurance.
For a current list of supported operating systems for these servers, refer to one of the following Web sites:
The ILOM firmware, system BIOS, and LSI firmware versions are usually updated in each new software release. Refer to the tables below for details on the released versions.
This section describes considerations that might affect the firmware update.
For software release 1.4, RHEL5 drivers are not available for the following option cards:
Once you update to version 1.16, downgrading the firmware to a previous version is not supported. Doing so can cause the LSI card and SCSI devices to become undetectable.
This section describes considerations that might affect the firmware upgrade. For issues on ILOM in general, refer to the Sun Fire X4100/X4200 Servers Product Notes.
The ILOM service processor might not successfully update the BIOS version, if a previous flash upgrade has failed. If the BIOS version is not correct after ILOM flash upgrade completes, use the -f force flag on the ILOM CLI load command, to force the BIOS flash upgrade.
This issue applies to ILOM 1.1.1 and earlier.
The host CPU and DIMM FRU information shown by the service processor is provided to the service processor during each BIOS power-on-self-test (POST). Therefore, after a BIOS/ILOM upgrade, this FRU information is empty until the first host BIOS POST.
This is expected behavior. Reset the server and allow it to complete POST during boot to repopulate the FRU lists.
After updating the system BIOS, you might need to clear CMOS settings to get serial console output from the host. This is because CMOS defaults might be changed from your existing settings in the new BIOS.
If you cannot get serial console output, clear the CMOS settings. To clear CMOS settings, use the following commands (in this example, the default username, root, and the default password, changeme, are used):
ipmitool -U root -P changeme -H SP-IP chassis power off
ipmitool -U root -P changeme -H SP-IP chassis bootdev disk clear-cmos=yes
where SP-IP is the IP address of the service processor.
The ILOM 1.1.1 and above firmware provides a new, more reliable flash layout. Because of the layout changes, special steps might be required to downgrade to previous ILOM 1.0.x releases.
You might have to perform the flash downgrade to 1.0.x process twice to reformat the flash layout to the old format. If the flash downgrade through GUI, CLI, or N1 System Manager, does not succeed the first time, retry a second time to complete the process.
The new ILOM flash process only powers off the host if a new BIOS version is needed. The ILOM CLI load command provides the -f option to force update of all components. Use the following command to force updating all firmware components:
load -f tftp://tftpserver/firmware.ima
where tftpserver is a trivial file-transfer protocol (TFTP) server and firmware.ima is the name of the image file, such as, ILOM.X4100-1.1.1.ima.
Sometimes after flashing an image on SP, the ILOM WebGUI will not allow you to log in and gives "Authentication fail" error. Clearing the cache and cookies of the Web browser enables you to log in as usual.
