Link Based IPMP on Shared IP Solaris Zone
Hi,

This may have already been raised previously so sorry for the duplication. What I want to achieve is have a physical server using link based IPMP setup in the global zone (not problem doing that) and then create a zone set as Shared-IP so when the servers NIC has an issue the IP will failover.

The issue I have is that when you build a zone and you "add net" and set the physical interface, you seem to have to specify an address. But the whole point of IPMP is that the second interface does not have an address, it gets inherited once the primary fails.

So what is have is

net:
address: 10.44.86.234
physical: bge0
defrouter not specified

net:
address: 0.0.0.0
physical: bge1
defrouter not specified

When the zone boots up I get this warning

# zoneadm -z zone1 reboot
zoneadm: zone 'zone1': WARNING: bge1:1: no matching subnet found in netmasks(4) for 0.0.0.0; using default of 255.0.0.0.

Running if_mpadm from the global zone does fail over the NIC ok in the Global zone and zone1.

So am I doing this a bit backwards or can I just ignore the warning.

Thanks,
Giles

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
