IPMP and Zones
in [Solaris]

From: pavelj on 4 May 2008 13:47 Hi guys. I have a v240 with 4 bge nics. I would like to run 2 zones on it, so each zone has it's one IP. What is also needed, is a nic level redundancy for each zone - 2 nics per zone. And a nic redundancy for the global zone - all 4 ports. The question is, can you define several IPMP groups on one nic. Smth like: bge0 bge1 bge2 bge3 zonegr_1 zonegr_1 zonegr_2 zonegr_2 10.0.0.1 10.0.0.2 globgr globgr globgr globgr 10.0.0.3 All the nics are in the same vlan, but it's very important that i can pull off 2 cables and only one zone will lose connectivity while the second one and global zone remain reachable - application redundancy testing. If you can point me to any docs\examples or share your your ideas what is the best way to achieve a config like this. It seems that if one defines the zone's physical device to a nic which is already a part of an IPMP group, you get the redundancy automatically. But found no mention wherever one can define so a nic will be a member of several IPMP groups. Thanks in advance.

My understanding was that you simply need to setup IPMP in the global zone. Any zone that uses an interface in the global zone's IPMP group will be protected. Say you add bge0 and bge1 to group ipmp1 in the global zone. Now if you add a network address to zone1 using physical port bge0, that address will fail over to bge1 when bge0 fails. The local zone never knows or cares.
From: pavelj on 4 May 2008 15:54 Hi, thanks. You're right, I'm well aware of what you've said. I did not mention it in my original post, all the IPMP config will be done in the global zone only. The zone will see only one NIC and the redundancy should be implemented in the global zone level. The question is: can i define 3 IPMP groups on the same NICs. 2 for zones, 2 nics for each group. And one for the global zone. Basically, can one NIC be a part of several IPMP groups? Thanks. > > My understanding was that you simply need to setup IPMP in the global > zone.
