Serial heartbeat

[Jun Zhang_4]

I connected the two nodes with a null modem cable. If I set one side up with a getty, the other side can login. When I run cmquerycl, the message still come up

Warning: Failed to find a configuration that satisfies the minimum network confi
guration requirements.
Minimum network configuration requirements are:
- 2 or more heartbeat networks OR
- 1 heartbeat network with local switch (HP-UX Only) OR
- 1 heartbeat network using APA with 2 trunk members (HP-UX Only) OR
- 1 heartbeat network with serial line (HP-UX Only) OR
- 1 heartbeat network using bonding (mode 1) with 2 slaves (Linux Only)

I thought that "1 heartbeat network with serial line" has been satisfied. What should I further do about the connected two serial ports? Do I need to let cmquerycl know about the devices name?

I would think this is not a problem.

so do you have a shared network for teh heartbeat as well as the serial link?

Hi Jun,

Can you post your configuration file?. I believe it is not recognizing the serial link.
