Oracle VM Manager: Server Pool Creation Page - 3

If we haven't assigned any users to this Server Pool, we can click on the Administration tab and allow users to this Server Pool. We had already created the user tarry, so let's assign him the role to manage this pool:

Now if we click on the Server Pools tab, we can see that there are a total of two users managing this Server Pool.

When we click on the Total: 2 link, we can see all of the users and their information.  We will see more on Users and Groups later, as we move ahead in this chapter:

In general, a Server Pool is named after the Server Pool Master, by default. To enable HA on the Server Pool, we will need all of the Oracle VM Servers in the Server Pool to have the following prerequisites:

• All Oracle VM Servers must use the same shared storage.
• Must be in the same OCFS (Oracle Cluster File System) cluster.
• Must have version 2.1.2 or above.
• Must have the same "Cluster root" for heartbeat purposes.
• Cluster root should be mounted on /OVS while all other storage could be located on /OVS/uuid.
• Mount points on /OVS to /etc/ovs/repositories. All storage must be mounted at /OVS and must be maintained in etc/ovs/repositories.
• Cluster root at /OVS must be shared and not local using Oracle's cluster file system OCFS2 on SAN/iSCSI or NFS on NAS. Default local storage is OCFS2 but is not supported with HA.

If all of these pre-requisites are met then you can enable HA.

Click Next and we will, depending upon the pre-requisites, get a message if HA is ready or not.
