IP migration when using Solaris Zones not possible

[Ivan Debnár]

Trying to setup mmm in enviroment, where there are several separate Zones configured, and
mysql is running inside a Zone. The idea is to have this zoned mysql "mirrored" in zone on
another server.

However, ifconfig commands are not available inside a zone, so IP adresses can't be added /
removed, ...

To solve this shortcomming, one could enhance the workflow and config, so that there will be
special mmm_agent running in global-zone, that could do the IP manipulation. Discover the
zone the host_ip is in, is no problem, adding an interface a attaching to a zone is one-liner as
well.
example add if:
global# ifconfig aggr2 addif 10.20.20.20/8 netmask + broadcast + up zone db-slave

example remove if:
global# ifconfig aggr2 removeif 10.20.20.20

We only need to declare the configuration somewhere - that node_ip's "global-zone" IP is this, and zone_name

What version of the product are you using? On what operating system?
MMM 2+, Solaris 10, mysqls in zones.

Just an idea to see if there is someone else interested, and probably to get feedback from
maintainers where and how best add this configuration.
