• Symptoms

• Unable to login to Netra CT900
• Malfunction of Node in CT900
• Chassis configuration issue
• Power issuse
• Network or communication issues to CT900

Data can be collected from the Netra CT900 server from the following components

1. Chassis related LEDS

2. Shelf Management Module (ShMM )

3. Four Switches (Two Switch Units per Switch Node board)

4. Node Boards (These cover a variety of architectures and operating systems)

• Chassis related LEDs

Note the status of the various chassis LEDS.
Refer to <Document: 1019516.1>

• Shelf Management Module (ShMM)

The ShMMs run a version of Linux with specific applications designed to manage the CT 900 shelf such as clia

There are two ShMMs one of which is active and the other back up. Failover can occur as a result of an error or can be instigated from the command line. Log into the active ShMM as root (via serial connection, telnet or ssh). See the following documents for cabling instructions

• Serial connection <Document: 1019404.1>

• Network connection <Document: 1019514.1>

Ensure that the connection is with the active ShMM using the shmstatus command (see example below). This is required unless it is necessary to investigate a problem that is specific to backup ShMM but note that many of the script commands will produce no output when run on the backup ShMM.

# clia shmstatus
Pigeon Point Shelf Manager Command Line Interpreter
Host: "Active"

• Run the summary script.

Note the summary script is the equivalent to the Solaris[TM] explorer and also includes information about shelf configuration such as board information.

Example:

# /etc/summary
send debug file /tmp/debug.log to PPS
# 

The script will generate a log file (/tmp/debug.log) which should be provided to Sun[TM] Support

• Capture the verbose output of the event log using the clia sel -v command

Example:

# clia sel -v
Pigeon Point Shelf Manager Command Line Interpreter

• Switches

It is beyond the scope of this document to go into detail about the switch architecture but the following discussion will allow basic configuration and statistics to be collected and provide a introduction into obtaining information from the switch.

Note: There are 4 Switch Units, 2 per switch slot. Each switch slot contains a switch on the Base Network and one on the Extended Network (Fabric). For full details it is necessary to run all the commands on all the Switch Units.

See the following documents for instructions and guidance for cabling

• Serial connection <Document: 1019404.1>

• Network connections <Document: 1019514.1>

Login into the required switch as admin and ensure all output is being logged via the Unix script command or equivalent. The default password is empty (just hit return key)

At this level the show command can be used to interrogate specific configuration settings.

Type show ? To find the options.

Example:

(ATS1160 Base) >show ?
bootpdhcprelay Display the value of BOOTP/DHCP relay parameters.
class-map Display DiffServ Class information.
classofservice Display class of service information.
dot1q-tunnel Display double VLAN Tunneling configuration.
dvlan-tunnel Display double VLAN Tunneling configuration.
garp Display Generic Attribute Registration Protocol
information.
gmrp Display GMRP interface information.
gvrp Display GARP VLAN Registration Protocol parameters.
ip Display IP information.
network Display configuration for inband connectivity.
port-channel Display port-channel information.
serial Display EIA-232 parameters and serial port inactivity
timeout.
serviceport Display service port configuration.
spanning-tree Display spanning tree information.
remotecon Display Telnet configuration information.
vlan Display VLAN configuration and configure VLANs.

• Obtain a print out of present switch configuration

First enter into user privilege mode using the ena command.

Then capture the current running configuration.

Example:

(ATS1160 Base) #show running-config

The output of the above commands should be sufficient to provide initial information

when contacting Sun Support Center about a Netra CT900 switch or connectivity problem.

• Node Boards

These boards can be a variety of architectures and running different operating systems. Use the appropriate tool such as explorer for Solaris and sosreport for Red Hat 5 to collect data.

Note the ShMM section above will collect data about board power cycles, hardware type and slots.
