For IP address issue, I will find about that concern and take
responsibility on risk for now.
For multiple altname's, as I found in
http://rpm.pbone.net/index.php3/stat/45/idpl/8711809/numer/5/nazwa/cman
it said that
Multi-home configuration .... Up to 9 altnames (10 interfaces in total) can be
used.
Is that the old document?
It's a current document (based on cman.5 in the distribution) but it is
actually very wrong. corosync only supports a maximum of 2 interfaces -
that's 1 only altname!

Using raw IPs is not recommended. I remember Chrissie explaining the reason
why a couple of years ago, but I can't remember that reasoning right not.
As for multiple altname's, that is not possible. Corosync's RRP (redundant
ring protocol) supports a primary and backup ring only.

I just already try this. It work !!
I don't understand that why there is no example in the Internet using
IP address as node name or altname.
But I cann't add more than one altname, can you give me the xml
example or the ccs command ?
Thanks

Dear List,
According to CMAN identify each node in cluster by hostname.
So I configure the IP address in /etc/hosts file as below.
...
172.16.7.1 node00.example.com
172.16.7.2 node01.example.com
...
So the corosync member show as below
[root@node00 ~]# corosync-objctl | grep member
runtime.totem.pg.mrp.srp.members.2.ip=r(0) ip(172.16.7.2)
runtime.totem.pg.mrp.srp.members.2.join_count=1
runtime.totem.pg.mrp.srp.members.2.status=joined
runtime.totem.pg.mrp.srp.members.1.ip=r(0) ip(172.16.7.1)
runtime.totem.pg.mrp.srp.members.1.join_count=1
runtime.totem.pg.mrp.srp.members.1.status=joined
My question is, is it possible to add more than one network for the HA
communicate between these nodes?
e.g. if 172.16.7.0/30 is down. And another network, which be main
access network, still be up. the HA will use UP network to talk
instead of the down one.
Thank you in advance.

You're asking about setting up corosync's redundant ring protocol,
correct?
If so, yes. You can use cman's 'altname' element to add a second name
for
the node, and then have that name resolve to the network you want to
use
as
the backup link.
