Sun Fire[TM] V490 and V890 systems with a certain Remote System Control Board (RSC) installed and running RSC Software Version 2.2.3, will see messages on the RSC's serial or network console ports that are likely to cause concern or confusion.

The following two examples show the messages seen -

Example 1:
The following message can be seen either when the RSC is rebooted or when the platform is powered on:

OCT 24 12:05:18 argualas: 00060003: "RSC System booted."
OCT 24 12:05:18 argualas: 00070001: "Unrecognized SC type, assuming 5016767"

Note:
It is not seen during a host reset:

OCT 24 12:42:34 argualas: 00060004: "RSC Request to Reset Host."
OCT 24 12:42:34 argualas: 00040002: "Host System has Reset"
OCT 24 12:42:36 argualas: 0004000b: "Host System has read and cleared bootmode."

Example 2:
The following failure message can been seen when performing an RSC Software update to Software version 2.2.3.

This is using the RSC software command, rsc-config, to perform the Software update:

This script will now update RSC, continue? (y|n): y

Changes

These messages are specific to the Reduction of Hazardous Substances (RoHS) RSC Board, part number 501-7314., and the presence of RSC Software Version 2.2.3

Cause

This issue is due to the part number in the RoHS RSC's SEEPROM being different to the non-RoHS RSC.

RSC software version 2.2.3 originally had only part number 501-6767 defined in the list of known part numbers.

The result is that the firmware calls out RoHS part number as being unrecognized.

There are now patches available to resolve this issue.

Solution

Relief/Workaround

Customers running Solaris 8 should apply patch:
119380-02 (or later) - RSC 2.2.3 bug fixes for Solaris 8

Customers running Solaris 9 or Solaris 10 should apply patch:
119381-02 (or later) - RSC 2.2.3 bug fixes for Solaris 9 and Solaris 10

Special Notes:
If the replacement of the RSC card is required for whatever reasons, only replace RoHS RSC card with non-RoHS version in a non RoHS machine. DO NOT put a non-RoHS RSC card in a RoHS machine.

If there is an RSC card replacement to a non-RoHS version, and if above error still occurs while doing flashupdate on non-ROHS card then do the following steps below:

Try method A first. If method A is not successful, use method B.

Method A: Reset rsc.

#/usr/platform/`uname -i`/rsc/rscadm resetrsc

Method B: Reseat the RSC card and reflash the RSC card.

   1. Power off the machine.
   2. Remove the powercords from the all the power supplies.
   3. Wait for 1 minute.
   4. Remove the RSC card.
   5. Wait for 1 minute.
   6. Insert the RSC card.
   7. Plug the power cords back into all the power supplies.
   8. Power up system.
   9. Log into Solaris a root and reflash the RSC.

      #/usr/platform/`uname -i`/rsc/rsc-config
