Created first zone of home Solaris box

I installed Solaris at home, actually Opensolaris, to try out a few things. I've already set up ZFS, so now onto Zones. I found a example to set up a zone a followed, to a 'T'. In using the IP address in the example, it caused the zone to be setup on another subnet, so that had to be rectified. I wanted to change the ip address in the zone to 10.1.1.220. These were the steps:

Prior to the creation of the Zone, I needed a place to put it. I needed a directory:

#Mkdir /coolpool/web-zone

Also unless the correct permissions are set on the directory, you will get a lot of error messages. The correct permissions are:

#chomd 700 /coolpool/web-zone

zonecfg -z web-zone

zonecfg:web-zone> add net

zonecfg:web-zone:net> set physical=afe0

zonecfg:web-zone:net> set address=10.1.1.220

zonecfg:web-zone:net> set defrouter=192.168.1.1

zonecfg:web-zone:net> end

zonecfg:web-zone> verify

zonecfg:web-zone> commit

zonecfg:web-zone > exit

Then booted zone from host:

zoneadm -z web-zone boot

Then zlogin and finish the install:

zoneadm -C console

Opensolaris

I purchased a quad-core Acer M5641 to run Solaris, Rocks, and other OSes on. I could never bring up Solaris, I decided to try another machine. I had an old Dell and Solaris came up right away, but since it was old, everything was slow. So I looked around the Hardware Compatibility List (HCL) and couldn't afford any of them. I asked the compatibility question of one os the Solaris email list and people recommended an entry level Dell server. By the time I had decided to purchase the Dell I wanted, it had been discontinued, so I settled on a Dell Poweredge T105. I had been warned that the network interface might be a problem. After several unsuccessful attempts, I went into the BIOS and disabled the network interface. Once I had Solaris installed, I looked around for a NIC. I had an unused card, installed it, and the network came up.

The T105 came with two internal drives. I had initially thought about mirroring the root disk, probably using dd, since they were identical. Instead I set it up as a separate partition using a ZFS filesystem on it. With that I was able to setup a snapshots on the filesystem. I'd like to set up dedupe on it as well, just to get an idea of how well it works.
