Troubleshooting Details

Cannot ping one or both control boards

Symptom:

One or both control boards are not responding to pings. The scrolling lights are also not active.

Resolution:

Assuming no physical problems (cabling, incorrect wiring, etc.), check the /tftpboot directory for hex-named files. These files are hard links to cbe.ima and cb_port. The filename is the hex equivalent of the IP addresses of the control boards.

southpark-ssp2:kenny% cd /tftpboot
southpark-ssp2:kenny% ls -il
total 5142
     13896 -r--r--r--   3 bin      bin       860244 Nov  1 11:37 C0A80101
     13897 -r--r--r--   3 bin      bin           10 Nov  1 11:37 C0A80101.cb_port
     13896 -r--r--r--   3 bin      bin       860244 Nov  1 11:37 C0A80201
     13897 -r--r--r--   3 bin      bin           10 Nov  1 11:37 C0A80201.cb_port
     13897 -r--r--r--   3 bin      bin           10 Nov  1 11:37 cb_port
     13896 -r--r--r--   3 bin      bin       860244 Nov  1 11:37 cbe.ima

      Make sure the hex IP address matches the IP address from /etc/hosts. Decimal to hex conversion can be done via printf in C-shell.

southpark-ssp2:kenny% grep southpark-cb0 /etc/hosts
192.168.1.1     southpark-cb0
southpark-ssp2:kenny% printf "%02X%02X%02X%02X\n" `echo 192.168.1.1|sed 's/\./ /g'`
C0A80101

If the values are incorrect (usually indicative of a network change), the links must be regenerated. To regenerate the links, first remove the incorrect file(s). Then run ssp_config cb as root.

# cd /opt/SUNWssp/bin
# ./ssp_config cb
Configuring control boards

Platform name     = southpark
Control board 0 = southpark-cb0 => 192.168.1.1
Control board 1 = southpark-cb1 => 192.168.2.1
Primary Control Board = 0

Is this correct? (y/n)n

Do you have a control board 0? (y/n)y

Please enter the host name of the control board 0 [southparkcb0]: southpark-cb0

Do you have a control board 1? (y/n)y

Please enter the host name of the control board 1 [southparkcb1]: southpark-cb1

Please identify the primary control board.
Is Control Board 0 [southpark-cb0] the primary? (y/n)y

Platform name     = southpark
Control board 0 = southpark-cb0 => 192.168.1.1
Control board 1 = southpark-cb1 => 192.168.2.1
Primary Control Board = 0

Is this correct? (y/n)y

Finally, as ssp, execute cb_reset.
