Sites

Sites are logical names that represent your sites. You must create sites at the KSYS level. All the Hardware Management Consoles, hosts, VIOS, and storage devices are mapped to one of the sites.

You can configure only two sites: home site and backup site. A workgroup or a host group can be active on any of the two sites. You can query the details about a site, active host groups on the site, and active workgroups on the site by using the ksysmgr command.

Sites can be of the following types:

Home site (or primary site)

Indicates the site where the workloads primarily run.

The ksysmgr command can display and configure the current attributes of the active site.

Backup site (or disaster recovery site)

Indicates the site that acts as a backup for the workload at a specific time. During a disaster, or a potential disaster, workloads are moved to the backup site.

You can create and configure sites by using the ksysmgr command.

The following figure shows the site attributes:

In this example, the Site 1 and Site 2 sites can switch back and forth as active and backup sites depending on where the logical partitions are currently located. You can set Site 1 as the active site for the logical partitions in the Host 11 host.
