Maintaining an Immutable Global Zone

Maintain the global zone by using the Trusted Path access. Trusted Path is only available on the console, so ensure that the console is accessible through the ILOM, a serial connection or through the graphical console.

Once a system is configured as an immutable global zone, use the break sequence on the console to access the trusted path console. Log in and assume the root role.

When a package update is performed, the first boot of the immutable Global Zone is read-write. The system needs these permissions to perform the required self-assembly steps. When the self-assembly steps have been performed, the system will reboot. In this second boot, the system becomes immutable again.
