Sun Fire X2100 Server - Version Not Applicable to Not Applicable [Release N/A]
All Platforms

Purpose

 

This document addresses problems whilst trying to connect to the X2100 server, both via the optional service processor and by telnet/ssh/rsh into the system via ethernet.

To discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the My Oracle Support Community - Sun x86 Systems

Troubleshooting Steps

Symptoms:

- Server not responding
- Server seems hung
- telnet/ssh/rlogin attempt times out or "Connection Refused"
- Console dead or not responding

Available Documentation:

Latest documentation on the Sun Fire X2100 server can be found at:

   Sun Fire X2100 Server Documentation

This troubleshooting guide makes reference to several of the documents at this location.



Steps to Follow:


Please validate that each troubleshooting step below is true for your environment. The steps will provide instructions or a link to a document, for validating the step and taking corrective action as necessary. The steps are ordered in the most appropriate sequence to isolate the issue and identify the proper resolution. Please do not skip a step.

 

Step 1. Verify system power

This is maybe an obvious step, and very easy to do if you are stood next to the platform - not as easy if the platform is remote.

The Documentation in the following links provides details what things should be checked and how to do so using the different platform management tools.

Refer to <Document: 1002939.1> "How to check if the platform is system powered on, on Sun Fire[TM] X2100 Servers"

If after you have checked for power and find that the system is powered off refer to the following Document, which explains how and what to check if your system is found to be powered off or will not power-on when checked.

Refer to <Document: 1011591.1> "How to check why the system is powered off, on Sun Fire[TM] X2100 Servers"

When the system is still powered off or you find any indicator for issues which causes the system to be powered of, please log the data as described in the document above and proceed with step 6 in this document to contact Oracle Support.

If you checked and the system has Power, please go to the next step.

Step 2. Verify SP connectivity

Be clear about how you are trying to contact your server.

If you are trying to connect via the Optional Service Processor, refer to the Sun Fire X2100 Server User Guide, Part Number 819-3721 at Sun Fire X2100 Server Documentation

If you are trying to contact the server via the platform network, go to step 4

NOTE: If after checking your SP connectivity you still have a problem, contact Oracle Support as outlined below

Step 3. Check for any errors on the system

If you are local to the system, check out the Service Indicator LED as shown in the attached.

Alternatively, you can interrogate the system remotely via IPMI as outlined in:

<Document: 1009698.1> "How to perform platform configuration, management, and data collection tasks with ipmitool on Oracle x86 servers"

If you find any abnormal conditions, raise a a service request as outlined in Step 6.

Step 4. Verify network connectivity

The commands to follow to check your network are outlined in the following document:

<Document: 1005533.1> "How to verify network connectivity on an x86 platform"

Step 5. Check your platform has not hung

If all the above check out, your platform may be hung (although if you can run the commands in Step 4, you can't be hung...)

Here are some documents which will be helpful if you are still unsure about whether you have a hung system:

<Document: 1008401.1> "Handling "System hangs" on an x86 Solaris System"

<Document: 1007053.1> "Analyzing System hangs on x86 Linux systems"

<Document: 1017776.1> "What to do on "System hangs" on an x86 Windows Systems"

Step 6. Raise an Oracle service request

At this point, if you have validated that each troubleshooting step above is true for your environment, and the issue still exists, further troubleshooting is required. For additional support contact Oracle Support.

NOTE: Since you can't contact your server, the amount of data you can gather is limited. For example, if you are running Solaris, you will not be able to complete an explorer data capture. However, in the event you can get the data (maybe you have problems contacting on one ethernet port only), the link below will show you how.

The following link references support documents assists in the gathering of information from your platform:

<Document: 1312847.1> "Sun Explorer Product Information Center help and forwarding data to an Oracle Engineer".

<Document: 1010057.1> "How to gather information on SuSE Linux Enterprise"

<Document: 1010058.1> "How to gather information on Red Hat Enterprise Linux"
