Re: Linux RHES3U4 abd SG 11.15 don't seem to accept 2 bonding interfaces
ifconfig bond0
or
ifconfig | more
# look for bond.
Make sure the interfaces are pinging.
To get this to work on my Fedora installation, I had to add a hack line to the network startup script. Every time I upgrade that hack is erased.

Re: Linux RHES3U4 abd SG 11.15 don't seem to accept 2 bonding interfaces
From the "managing" manual:
"IP addresses are configured only on each primary network interface card. Multiple IP addresses on the same network card must belong to the same IP subnet."
Is there any reason you are doing this?

Re: Linux RHES3U4 abd SG 11.15 don't seem to accept 2 bonding interfaces
We have 2 network adapters, and we want it to be redundant, which is why we use bonding (Which gives you one network adapter, bond0). For ServiceGuard you need at least 2 networks (HB and normal network) so HP advised us to VLAN the bonding interface. In theory this should work. In practice it does not.
Our initial plan was to use the ppp0 interfaces (through a null-modem cable on the serial port) but HP advised against this (the machines are in the same rack, so distance is not a problem).
I think to solve this problem, we will revive the PPP plan. That means we will have ppp0 and bond0.

Re: Linux RHES3U4 abd SG 11.15 don't seem to accept 2 bonding interfaces
Setting up a VLAN doesn't help. And you still have the problem of a subnet that can't be monitored. Go back to a single bond. If you have the opportunity to add another NIC HBA, then it is best to bond that to one of the built-in NICs (I assume there are two built-in NICs in your servers.)

Re: Linux RHES3U4 abd SG 11.15 don't seem to accept 2 bonding interfaces
This will give you the redundancy of network failover, an d if a network cable or NIC fails, this will do a local lan switch.
The problem does exist that you now only have one subnet, and hence one heartbeat. To create a better configuration, you could add another NIC in each node and have them just as a heartbeat lan.

To my knowledge we do not support using ppp for Serviceguard

Re: Linux RHES3U4 abd SG 11.15 don't seem to accept 2 bonding interfaces
in the meantime I've made a case with HP Support Netherlands, it seems that neither PPP or VLAN over Bonding are supported by Linux >:-( The funny thing is, we had a RHCE HP consultant who said PPP was possible but not advisable, and who also told us that Vlanning over Bonding should be possible. Let's just say we are not too happy with HP consultancy at the moment. (and that's putting it mildly)
We have since made it work by adding another ethernet adapter. We were trying to save the PCI slot associated with this for future expansion.

SolutionI certainly would have said that this could not be done when planning a Serviceguard on Linux cluster.
All I can do is give a small apology on behalf of HP
