How to use Solaris Live Upgrade (LU) patching
Some versions of Solaris have the capability of maintaining multiple instances of the Base Operating Systems (BOS). The user can boot any one instance of the BOS which is called the active instance. The instance which has not been booted remains as a stand-by instance. TrueSight Server Automation supports updates on the stand-by BOS without affecting system files on the active BOS.
Enabling patch remediation on stand by BOS instance of a Solaris server
Patch analysis is always performed on the active BOS. To enable patch remediation on the stand-by BOS of a particular Solaris server, perform the following steps in the TrueSight Server Automation Console:

- Enter the name of the alternate boot environment (stand-by BOS instance) that you want to remediate, in the
Although TrueSight Server Automation does not manage the stand by BOS instance automatically, you can manually create and activate the stand-by instance by running the following commands on the target.
Create a stand-by BOS instance (before applying the patches)
lucreate -n <name of
stand-by boot instance>
Reboot the target and activate the stand-by instance (after applying the patches)
luactivate <name of stand-by boot instance>
