SnapScale/RAINcloudOS 4.1 Administrator’s Guide
4 – Network Settings
The Utility IP address can be used to reliably access a specific node by a known IP address,
and is particularly useful for backup agents and media server installations. The Utility IP
address is assigned to the node in addition to its static IP address automatically assigned from
the cluster IP address pool, as well as the Management IP if the node serves as the
Management node.
NOTE: The Utility IP address must be located on the same subnet as the SnapScale Client network.
The address should be assigned BEFORE installing a backup agent or media server on a
node. Once the Utility IP address has been assigned, you must add a host record to the DNS
server for the node name pointing to the Utility IP address (do NOT add it as another host
record for the cluster name).
Only one Utility IP address can exist on a cluster. The Web Management Interface will not
allow a new Utility IP address to be created if a Utility IP address currently exists, or when an
address does not exist but there are one or more offline nodes (which may have an address
already configured on them). The Utility IP address also must not be the same as the
Management IP address or any existing address in the cluster IP address pool.
Configure a Utility IP Address:
1.
On the
Utility IP Address
page, in the empty field, enter a
static IP address
on the
same subnet as the IP address pool on the Client network.
2.
Using the drop-down list, select the
cluster node
to which the Utility IP address will be
assigned.
3.
Click
OK
.
4.
At the confirmation page, click
Save Changes
.
The Utility address is displayed on the
Network Information
page (
Network > Information
)
beneath the static address of the node on which it was configured. The Utility IP address
remains with the node, even if the node is restarted or goes offline.
