How to Create and Activate Multiple Boot Environments on a solaris10 Branded Zone - Creating and Using Oracle® Solaris 10 Zones

Language:

Become an administrator.
For more information, see Using Rights Profiles to Install and Manage Zones in Creating and Using Oracle Solaris Zones.
Configure the solaris10 zone.
In this procedure, the zone s10_zone with the configuration file /zones/S10_ZONE.cfg is used on the global zone, global.
```
global$ zonecfg -z S10_zone -f /zones/S10_ZONE.cfg
```
Install the solaris10 zone.
The flash archive image file /zones/s10-system.flar is used in this procedure.
```
global$ zoneadm -z S10_zone install -u -v -a /zones/s10-system.flar
```
Boot the solaris10 zone.
```
global$ zoneadm -z S10_zone boot
```
On the solaris10 zone, create a new boot environment using ZFS commands.
1. Create a ZFS snapshot.
  The snapshot rpool/ROOT/zbe-0@snap is used in this procedure.
```
S10_zone# zfs snapshot rpool/ROOT/zbe-0@snap
```
2. Clone and mount the new ZFS snapshot.
  In this case, the ZFS snapshot rpool/ROOT/zbe-0@snap is mounted to / and cloned to a new ZFS snapshot,rpool/ROOT/zbe-1:
```
S10_zone# zfs clone -o mountpoint=/ -o canmount=noauto rpool/ROOT/zbe-0@snap rpool/ROOT/zbe-1
```
3. Promote the new ZFS snapshot.
```
S10_zone# zfs promote rpool/ROOT/zbe-1
```

Patch the new boot environment.

Mount the new ZFS snapshot.

S10_zone# zfs mount -o mountpoint=/mnt rpool/ROOT/zbe-1

Run the patchadd command on the snapshot mount point.

S10_zone# # patchadd -R /mnt -d /var/tmp  
S10_zone# zfs unmount rpool/ROOT/zbe-1

S10_zone# zfs unmount rpool/ROOT/zbe-1

Activate the new boot environment.

S10_zone# zfs set com.oracle.zones.solaris10:activebe=zbe-1 rpool/ROOT
S10_zone# shutdown -y -g 0 -r

Boot the zone to have the changes take effect.
```
global# zoneadm -z S10_zone boot
```
