- This is not an official HP response, but thats how I understand it.
- (and how it works on our s300 cluster)
-
- You can use two Lan cards per machine. One for the cluster lan
- and one for the outside world. According to documentation, you
- need to use the built in for the cluster Lan and the eisa for
- the other.
-
- On the /etc/rc file you need to "power up"
- both lan cards. (This is described in the manual)
-
- Cnodes can only boot from a single server lan (i.e., you
- can't have half booting from card 1 and half from the other card).
-
- /etc/clusterconf specifies both the "boot" lan card of the server
- and the lan-cards of the cnodes.
-
- I hope that helps.
