Zones - NAT'ing
Hi gurus.

Not such a problem, more of a proof of concept.

Ive got two zones :- database-1 and database-dr-1 on two different servers. Both zones have different ip addresses.

I want to copy the whole zone database-1 over to database-dr-1, which is simple enough, but I want to install some sort of NAT / Ip fitler on the dr zone, that converts the zones ip, into the ip of the copied over zone. Possible ??

If this is possible, I can then not bother with updating the applications once copied over, just have an extra network layer which converts the copied over IP / host details, into the dr zone.

Any ideas ?

Both physical servers are connect to a san, which will soon sync up with each other. This means if I install the zone / apps on SAN storage, on the event of a failed site, I could mount the storage / zone on the DR server and fire it up. Hence the question about being able to NAT etc etc.


Basically, Im uses zones, and am trying to think of ideas about DR. So, any ideas of zones and DR would be great full.

NAME

       brands - alternate operating environments for non-global zones

DESCRIPTION

       The branded zone (BrandZ) framework extends the Solaris Zones infrastructure described in zones(5) to include the creation of brands, which
       provide non-global zones that contain non-native operating environments.

       The term "brand" can refer to a wide range of operating environments. All brand management is performed as extensions to the current  zones
       structure.

       Every  zone is configured with an associated brand. The brand type is used to determine which scripts are executed when a zone is installed
       and booted. In addition, a zone's brand is used to properly identify the correct application type at application launch time.  The  default
       is the native brand.

       A  branded  zone  will support exactly one brand of non-native binary, which means that a branded zone provides a single operating environ-
       ment. Once a zone has been assigned a brand, that brand cannot be changed or removed.

       BrandZ extends the zones tools in the following ways:

	   o	  A brand is an attribute of a zone, set at zone create time.

	   o	  The zonecfg tool (see zonecfg(1M)) is used to set a zone's brand type and configure the zone.

	   o	  The zoneadm tool (see zoneadm(1M)) is used to report a zone's brand type and administer the zone.

   Device Support
       The devices supported by each zone are documented in the man pages and other documentation for that brand. The zones infrastructure detects
       any  attempt  to  add  an  unsupported device and issues a warning to the administrator. If the administrator chooses to add an unsupported
       device despite that warning, that device might or might not work as expected. The configuration will be untested and unsupported.

ATTRIBUTES

       See attributes(5) for a description of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
