Discover a Kernel Zone
12c Release 3 (126.96.36.199.0)
This guide provides an end-to-end example for how to use Oracle Enterprise Manager Ops Center.
This guide explains how to discover an Oracle Solaris 11 kernel zone.
Oracle Solaris 11 kernel zones each have a separate kernel from the global zone, giving you more flexibility in terms of their operating system level.
Oracle Enterprise Manager Ops Center provides basic monitoring and management for Oracle Solaris 11 kernel zones. To enable these capabilities, you must fully discover the kernel zone.
Unlike other types of zone, kernel zones are not fully discovered and managed when the global zone is discovered. The operating system of the kernel zone must be discovered in addition to the global zone, although the two discoveries can be combined in a single discovery job.
In this document, you will create and use a discovery profile to discover a global zone, a kernel zone hosted on that global zone, and the kernel zone's operating system.
See Related Articles and Resources for links to related information and articles about kernel zones.
You will need the following:
A configured Enterprise Controller.
A user with the Ops Center Admin role.
A global zone hosting a configured kernel zone.
The IP addresses of the global zone and kernel zone.
A discovery profile is a combination of an asset type, a set of host names or IP addresses, and a set of credentials. You can use discovery profiles to locate specific systems such as a global zone and a kernel zone.
The tasks that are covered in this section are as follows:
Assets are managed using a set of credentials. You can create or use existing credentials to discover and connect with assets.
When creating a credential, if your target OS supports root login, enter a root user (or other privileged user) and leave the Privileged Role field blank. If the target OS does not support root login, then enter a non-root user that can login to the OS and also specify a root/privileged user in the Privileged Role field.
To discover a global zone and a kernel zone, create one set of credentials if the zones have the same login information, or create two sets of credentials if the zones have different login information.
To create credentials, perform the following steps:
Custom SSH Key: If you prefer not to use password-based SSH credentials, you can create an SSH key to access to the operating system.
Ops Center Key: A new SSH key pair is generated. During discovery, Oracle Enterprise Manager Ops Center configures key-based authentication by installing the generated public key in the login account. Note that different credentials must be used to discover the Operating System before the new public key has been installed.
After the non-privileged user logs in, Oracle Enterprise Manager Ops Center runs the "su" command to elevate the user to a root/privileged user.
The credentials are created.
You can create a discovery profile and then run a discovery using the profile. You can provide some discovery information, such as the targeted IP addresses and the discovery credentials, during profile creation or when the profile is run.
After you have created the discovery profile, you can run it to discover and manage the global zone and kernel zone.
This procedure assumes that you have already created a discovery profile with an IP range, a specified network, and discovery and management information.
The discovery job is launched. When it is complete, the global zone, the kernel zone, the kernel zone operating system, and any nested zones installed on the kernel zone are displayed in the UI.
