Solution Type Sun Alert Sure Solution 1019883.1 : Sun Blade 6000 Chassis Monitoring Module (CMM) or Sun Blade T6300 Server Module may Exhibit Erroneous "Failed", "Hot Insertion", and "Removal" Messages
PreviouslyPublishedAs 248186 Bug Id <SUNBUG: 6720809>, <SUNBUG: 6695705>, <SUNBUG: 6762599> Product Sun Blade 6000 Modular System Sun Blade T6300 Server Module Date of Workaround Release 07-Jan-2009 Sun Blade 6000 Chassis Monitoring Module (CMM) or Sun Blade T6300 Server Module may exhibit erroneous "Failed", "Hot Insertion", and "Removal" messages: 1. Impact Sun Blade 6000 Chassis Monitoring Module (CMM) and Sun Blade T6300 Server Module may exhibit erroneous "Failed", "Hot Insertion", and "Removal" Messages. 2. Contributing Factors This issue can occur on the following platforms:
If the blades cannot be inspected visually, the following procedure can be used to identify affected blade(s): 1. Access the SP of the Target blade 2. Type "shownetwork" 3. Set the SP to "ssqa" mode by typing the following: setsc sc_ssqamode true "xyz"where "xyz" is the last nibble from the three last bytes from the mac address. 4. Get the "Four Eyes" firmware version: sc> i2cp 0x20 3 2 0 0 1.If the above command returns a value == 12, the blade is affected by this issue. If the command returns a value == 14, the blade is not affected. Note 2: The error messages mentioned above are completely harmless and do not affect the systems performance, functionality or reliability. Note 3: This issue can occur in Sun Blade 6000 configurations with any population of Sun Blade T6300 server modules. They are most apparent when Sun Blade T6300 server modules are plugged into slots 6,7,8, or 9. This issue rarely occurs in Sun Blade 6000 configurations that are less populated with Sun Blade T6300 server modules when plugged into the lower slots. Note 4: This issue can occur on the systems listed above irrespective of the OS/ALOM versions in use. 3. Symptoms If the described issue occurs, messages similar to the following will be seen when the T6300 Service Processor (SP) is powered on: Example of T6300 SP messages: SC Alert: PSU at MP/PS1 has been removed.Example of chassis CMM events: 1319 Thu Jan 1 00:01:56 1970 Chassis Action major Hot insertion of /CH/NEM14. Workaround All T6300 blades should be upgraded to the latest firmware version 6.7.2 (delivered in patch139438-02) as this new firmware may decrease the chances of the described issue from occurring. In Sun Blade 6000 configurations populated with 2 or 3 Sun Blade T6300's, move the blades to the lower chassis slots while moving the other blades (i.e T6320) to the higher slots. Also, CMM ILOM firmware should be at 2.0.3.2 or later. This has been known to decrease the chances of the described issue from occurring. Alternatively, setting the "sys_eventlevel" to 0 or 1 in the T6300 ALOM will suppress the messages from being logged to the "/var/adm/messages" logs. Level 1 is for critical messages and 0 is for zero messages to be logged to the "/var/adm/messages" file. It is recommended that the "sys_eventlevel" be set at level 1 so that critical messages are still logged. Note: This will not stop the messages from being logged on the CMM or the T6300 SP's as there is no way to suppress these. 5. Resolution This issue is addressed in the following platforms:

All rights reserved. Internal Comments The ultimate fix will be a two part fix including T6300 blade replacement to update the motherboard FourEyes I2C bus bridge chip firmware to v1.4 which provides I2C bus Dynamic Arbitration and Dynamic Priority features. All blades must use this polling mechanism to ensure fair access to the I2C Bus and to prevent the timeouts that produce the false messaging. In addition the system firmware must be upgraded to v6.7.1 which contains ALOM code to enable the dynamic arbitration/priority feature within the bridge chip. These fixes will be released in an upcoming FAB once final testing is complete.
