Features Introduced in 5.15.0

This section provides a brief description of the new features in 5.15.0. For detailed information on these features, refer to the Sun Fire 6800/4810/4800/3800 Systems Platform Administration Manual (part number 817-0999-10) and the Sun Fire 6800/4810/4800/3800 System Controller Command Reference Manual (part number
817-1000-10).

Automatic Diagnosis and Domain Restoration

The following error diagnosis and domain restoration capabilities are enabled by default:

• Auto-diagnosis (AD) engine

The AD engine detects and diagnoses hardware errors that affect the availability of a platform and its domains. The AD engine analyzes a hardware error and if possible, identifies the field-replaceable units (FRUs) associated with the hardware error. The AD engine records the diagnosis information for the affected components and maintains this information as part of the component health status (CHS).

Auto-diagnosis information is reported through platform and domain event messages. When you see auto-diagnosis event messages, contact your service provider so that the appropriate service action can be initiated.

• Auto-restoration of paused domains

After auto-diagnosis, a domain that was paused due to a hardware error will be automatically rebooted. If possible, any components associated with the hardware error are also disabled (deconfigured) from the system.

For further information, see the "Diagnosis and Domain Restoration" chapter in the Sun Fire 6800/4810/4800/3800 Systems Platform Administration Manual.

Automatic Recovery of Hung Domains

The system controller automatically monitors domains for hangs in which a domain does not respond to interrupts or a domain heartbeat stops within a designated timeout period. When the hang policy parameter of the setupdomain command is set to reset, the system controller automatically performs an externally initiated reset (XIR) and reboots the hung domain. For additional information, see the "Diagnosis and Domain Restoration" chapter in the Sun Fire 6800/4810/4800/3800 Systems Platform Administration Manual.

Component Location Status

The physical location of a component, such as slots for CPU/Memory boards or slots for I/O assemblies, can be used to manage hardware resources that are configured into or out of the system. A component location has either a disabled or enabled state, which is referred to as the component location status. You can enable or disable components based on their physical location in the system.

You change a component location status through the setls command. This command replaces the disablecomponent and enablecomponent commands, which were previously used to blacklist and enable components, respectively.

---

Note - Sun recommends that you use the setls command rather than the disablecomponent and enablecomponent commands, even though those commands are still supported in 5.15.0.

---

For additional information, see the "Introduction" chapter in the Sun Fire 6800/4810/4800/3800 Systems Platform Administration Manual.

Domain HostID/MAC Address Swap

A new setupplatform parameter, the HostID/MAC Address Swap, enables you to swap the HostID/MAC address of one domain with another. This feature is useful when host-licensed software is tied to a particular domain HostID and MAC address, but you need to run that host-licensed software on another domain. You can swap the domain HostID/MAC address with that of an available domain and then run the host-licensed software on the available domain, without encountering license restrictions tied to the original HostID/MAC address.

---

Note - If you swap the HostID/MAC addresses between a pair of domains, but you need to downgrade to an earlier firmware release, you must restore the original domain HostID/MAC addresses before performing the downgrade. For details, refer to the "General Administration" chapter in the Sun Fire 6800/4810/4800/3800 Systems Platform Administration Manual and the Install.info file included with the firmware.

---

Commands New for 5.15.0

The setls command replaces the enablecomponent and disablecomponent commands, which have been deprecated starting with the 5.15.0 release. For details, refer to the setls command description in the Sun Fire 6800/4810/4800/3800 System Controller Command Reference Manual.

Commands Modified for 5.15.0

The following SC commands were changed in 5.15.0:

• disablecomponent - Deprecated but still supported. Use the setls command instead.
• enablecomponent - Deprecated but still supported. Use the setls command instead.
• setupdomain - Removed the error-diagnosis parameter. The error diagnosis feature is now enabled by default.
• setupplatform -p hostid - New HostID/MAC Address Swap parameter.
• showcomponent - The POST status includes a new value called chs (component health status). The chs value for a disabled component indicates that further service action is required by your service provider.
• showdomain - Removed the error-diagnosis parameter.
• showplatform -p hostid - New HostID/MAC Address Swap parameter.

General Information

Sensor Status Messages

In 5.15.0, the following types of status messages are displayed on the platform console when sensors detect an abnormal condition for a component:

• An over limit status message indicates that the value is outside the acceptable range for the component. For example:

/NO/SB0, sensor status, over limit (7,1,0x201000d00050000)

• An under limit status message indicates that the value is within the acceptable range for the component. For example:

/NO/SB0, sensor status, under limit (7,2,0x201000d00050000)

Firmware Compatibility

System boards with 5.12.x firmware are compatible with those running 5.13.0 through 5.15.x firmware; system boards running 5.11.x are not. You can check the firmware compatibility of your boards by running the
showboards -p version -v command. COD boards must be running firmware version 5.14.x or 5.15.x.

The information displayed indicates whether the firmware for each board is compatible with the ScApp version running on the SC. For details on verifying firmware compatibility, refer to the Install.info file included with this firmware release and the showboards command description in the Sun Fire 6800/4810/4800/3800 System Controller Command Reference Manual.

To simplify system administration, update all your system boards to the same firmware version and activate the new firmware version on your domains as soon as possible. Activate the domain firmware by running the setkeyswitch off and setkeyswitch on commands. For details on updating your system firmware, see the release-specific Install.info file included with each release of the firmware.

Firmware Upgrade and Downgrade

Instructions for upgrading firmware are provided in the Install.info file included with this firmware release. The Install.info file also contains instructions for downgrading to an earlier version of the firmware.

---

Caution - If you have a redundant system controller (SC) configuration, you must first upgrade the firmware on the spare SC, then on the main SC, as explained in the Install.info file.

---

Power Supply Failures

In some cases powering off or powering on a power supply after you upgrade to firmware version 5.15.x can cause a power supply fault. The power supply failure might exhibit the following characteristics:

• Only the amber ready LED of the power supply is illuminated.
• The showboards command output identifies the Status for the power supply as Failed or the Component Type as No Grid Power.

Use the following workarounds to resolve the power supply failure. Start with
Workaround 1. If this workaround is unsuccessful, perform Workaround 2. If the second workaround is unsuccessful, perform Workaround 3.

• Workaround 1 - Turn the power supply switch off and then on. However, if you have a Sun Fire 6800 system, perform Workaround 2 instead, as the power supplies do not have a switch.
• Workaround 2 - Remove the failed power supply from the system, wait 20 seconds, then put it back in. If its green power on LED is not the only LED illuminated, repeat the procedure until it is. Several attempts may be necessary.
• Workaround 3 - Reboot the SC, then use the power on command to turn on the power supply.

Known Sun Fire 6800/4810/4800/3800 Systems Limitations

This section describes only those bugs with potentially significant impact. The README file lists all bugs, including those seen only internally at Sun.

SC Hangs After Automatic setkeyswitch off (RFE 4454599)

Manual reset of the SC has no effect.

Workaround: Do the following:

1. Connect to each active domain through a network connection, such as telnet or rlogin.

2. Shut down each domain, if possible.

3. Power down the Sun Fire system, then power it up again.

No LED Fault Indicator on System Board After the Board Fails POST (RFE 4454623)

Workaround: Run the showlogs or showboards command (from the platform shell) to show errors and the test status of a faulty system board.

SC Prompt is Changed and Not Sync After Replacing SC With Old FW From Another Machine (BugID 4740301)

After the spare SC is replaced and SC failover is enabled, the prompt shown on the spare SC is that of the machine from which it was removed.

Workaround: Execute setupplatform -p network to change the IP address and SC host name, reboot the SC, then do an SC failover.

Cannot Boot the Solaris Operating Environment if Bus 1 of Schizo0 is Disabled in a Single I/O Board Domain (BugID 4779052)

If there is only one I/O boat in a domain, disabling bus B of an I/O controller results in an error message indicating that there are no good I/O boards available to boot the Solaris operating environment.

Workaround: Disable only the slots on the bus that are not working instead of the bus.

Platform Console Does Not Report SEEPROM Errors But Domain Console Does (BugID 4793968)

Some messages, for example SEEPROM-related information, are displayed on the domain console but not the platform console.

Workaround: Check all system logs.

Sun Management Center Domain Failed to Recognize V2 CPU Board and Treated it as an Unknown Board (BugID 4808259)

Sun Management Center 3.0, Platform Update 4, does not recognize CPU V2 board components.

Workaround: None.

Processor Stuck in OpenBoot PROM (OBP) When OBP Console Buffer Full (BugID 4825233)

In Sun Fire 6800/4810/4800/3800 systems, console messages for the Solaris operating environment and OBP are placed in domain console buffers that are accessed by the system controller. If the system controller is unavailable, the buffers may fill up with messages, which in turn affects domain functionality. OBP appears to be stuck, while it waits for additional buffer space to become available.

Workaround: Try to ensure that the system controller is always available, or that it is unavailable only for a short period. You can also do the following to mitigate this situation:

• Try to keep the system free from hardware errors, as such errors typically generate numerous error messages that are directed to the console.
• Change the syslog.conf file so that little or nothing is sent to the console.

WDR Solaris_WDRAttachmentPoint/
Solaris_CHSystemBoard Fails to Recognize COD (BugID 4839027)

WBEM-based dynamic reconfiguration operations do not recognize COD CPU/Memory boards. For example, when you check instances of Solaris_WDRAttachmentPoint, information displayed for the Solaris_CHSystemBoard class will not include information on any COD boards in the system.

Workaround: None.
