How to troubleshoot a reported down XSCFU.

Fix

Many of the down XSCFU issues are actually due to connectivity issues.

To troubleshoot these issues start by verifying the XSCFU is actually down using the following procedures:

LED Status:

• Collect the LED status from the XSCFU ( table 2-10 / 2-11 ) and OPNL ( tables 2-3 and 2-4 ) then compare them with tables in the System Service Manual.  If there is an open case for this issue place the LED statuses in the case notes.
• If the system is not powered up then apply power to the system. 
• If the system is powered up then proceed to the "Serial Port" section.

Serial Port:

• Are there any devices connected to the serial port? ( ref: Chapter 3 of the install guide ).

• If yes:

• Check to see if the serial port is active and if there is any output.
  
  Note:  Ensure the cable plugged into the serial port is not ethernet.  Ethernet ports are labeled Ethernet#0 and Ethernet#1.
• If there is output can we login to the XSCFU ( see <Document 1297895.1> "How to reset Mx000 XSCF password" for password issues )?
• If there are errors on the console, cut and paste them into a text file for updating to the case notes.  Search for the error on support.oracle.com and follow the guidance provided there.
• If there is no output to the console then skip to Network Checks.

• If no then skip to Network Checks.

Network Checks:

• Can we ping the XSCFU interface?
• Can we telnet / ssh to that interface from a system on the same subnet. 
  If we can reach the XSCFU from a system on the same subnet but not from a different subnet then the routing on the XSCFU should be checked.
• Can we log into a domain on this platform?
• If we can login to a domain then using "ifconfig -a" we should see the dscp interface "sppp0".
  
  
  # ifconfig -a
  lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
          inet 127.0.0.1 netmask ff000000
  bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
          inet 10.79.250.186 netmask ffffff00 broadcast 10.79.250.255
          ether 0:b:5d:dc:10:d0
  sppp0: flags=10010008d1<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST,IPv4,FIXEDMTU> mtu 1500 index 3
          inet 192.168.224.2 --> 192.168.224.1 netmask ffffff00
          ether 0
  log into the XSCFU using the dscp address ( in this case 192.168.224.1 ).  Check the network setting to ensure they are correct ( shownetwork -a, showroute -a, shownameserver, showssh, showtelnet ). 
  Network configuration information can be found in the SPARC Enterprise M3000/M4000/M5000/M8000/M9000 Servers Administration Guide
