Goal

Accessing service mode on the Sun SPARC(R) Enterprise Mx000 Series platform and clearing faults.

Fix

Enabling and using service mode.

Step 1.  Log into the XSCF and verify you have the appropriate privileges.

XSCF> showuser
User Name:         fieldeng
UID:                    101
Status:                 Enabled
Minimum:            0
Maximum:           99999
Warning:             7
Inactive:              -1
Last Change:       Feb 07, 2007
Password Expires:  Never
Password Inactive:  Never
Account Expires:     Never
Privileges:              mode  <------ Needed
                              fieldeng

NOTE: If you do not have mode privilege you will need to do the setprivileges command, as only users with mode privileges and a valid password can enter service or escalation mode. Please also note that the mode value for privileges is not documented in the setprivileges man page.

Very important - setprivileges overwrites a user's current privileges and does NOT append privileges to the existing list. To add privileges to a user, you must re-list all existing privileges as well as the new privileges.

Example:

XSCF>setprivileges user platadm useradm platop fieldeng mode

Step 2. Create a Password. 

This is done at https://modepass.us.oracle.com
There is a backup server at https://modepass-bak.us.oracle.com

Changes have been made to the OPL Password Generators to allow TSC to collect some minor additional information when a password is generated.  We will use this data to improve our processes, gather support for fixing bugs, or perhaps indicate where additional user features are necessary to reduce costs associated with servicing the product.  We are soliciting your support by requesting that you enter valid data when you generate service or escalation mode passwords.

• If you are generating a password for a service request, please select Customer, then supply a reason for generating the password, including a CR# if you know it, in the REASON field and a valid case # in the CASE# field.
  Note - passwords are not to be given to customers. 
• If you are generating a password for internal use, REASON is still required, but CASE# is not.

Please try to provide accurate and useful information considering our intended usage.  It only takes a few extra seconds to record useful data, and it will benefit everyone.

Here are some examples of useful information in the REASON field:

• need to clear the deconfigured status on MBU_A due to a power failure (see Bug ID 6729779)
• customer is running XCP 1060 and has a "degraded" IOU after a boot failure (see Bug ID 6586462 & Bug ID 6639839)

Here are some examples of less useful information in the REASON field:

• need it
• deconfigured parts, clearfru, clear faults, enable faulted component

In order to create a password you will need the following data from the XSCF:

1. The version of XSCF: version -c xscf
2. The serial number:  showhardconf

***** WARNING: The data you input into this site is CASE SENSITIVE. Be sure to use the appropriate case, or you will NOT be able to log into service mode. ****

One of the commands used is showhardconf.  showhardconf -M makes it a little easier to get the serial number, which is at the top of the output.

The password will be a long list of words.  You can copy and paste them into the passwd prompt when it comes time.  

Step 3. There are two steps to gain access to service mode. 

The service password can be pasted into the below password prompt. Hit a return afterwards and wait.  You may need to hit another return. You will get a secondary password to plug into the service command.

XSCF> enableservice
Service Password:

**** **** **** ***  ***  ***
**** **** ***  **   **** ****
***  **** **** ***  **** ****
**** **** **** ***  ***  ****
**** **** **** **** **** *
Mode password is: WALL CAT  BY


XSCF> service
Mode password: **** *** **

For M8000/M9000: please note that you need to enableservice on the Active XSCFU to access service on the Standby.

Step 4. Clear the fault.

The clearfault command has an excellent manpage which gives the paths to the FRUs should you not be 100% sure of the path to input into the command.

Example:

service> clearfault /MBU_A/MEMB#0/MEM#0A
clearfault: Fault cannot be cleared for this FRU.
FRU will be marked to clear fault on next circuit breaker off and on.
Continue? [y|n]: yes
Fault will be cleared after circuit breaker off and on


The fault should now be cleared.  Depending on the component you will be prompted with extra instructions as indicated above. Form more information on clearing faults, and FMA related errors consult <Document 1007101.1> Fault clearing and LEDs behavior.


Step 5. Verify the fault is cleared.

service>  showstatus

Step 6. Exit and disable service mode

service> exit
XSCF> disablemodes

IMPORTANT: if you don't disable the service mode, anyone can re-enter the service mode with the  3-words mode password that has been displayed previously.



Internal Comments
About entering escalation mode

The procedure to enter escalation mode is the same as for service mode except for:

1. The commands are: enableescalation / escalation
2. The password is different
3. The password is only delivered upon request to TSC
