-
From the
Resource to Duplicate list, select a node.
Select a node that is of the same type as the other nodes within the resource group.
-
In the
Number of Instances box, enter the number of node instances that you want to add to the resource group.
PowerFlex Manager requires a minimum of two nodes in a NAS cluster. You can expand the cluster up to a maximum of 16 nodes.
-
Click
Next.
-
Under
PowerFlex Settings, specify the
PowerFlex Storage Pool Spare Capacity setting by choosing one of the following options:
- Recommended Spare Capacity <n>% sets the spare capacity to 1 divided by the current number of Storage Data Servers (SDSs) in the protection domain, plus the number of nodes that you want to duplicate. For example, if you have three SDSs and you want to add one more node instance, the recommended spare capacity is set to 25 percent based on the formula 1/4.
- Current Spare Capacity <n>% sets the spare capacity to 1 divided by the current number of SDSs in the protection domain. For example, if you have three SDSs in the protection domain, the current spare capacity is set to 34 percent, based on the formula 1/3, rounded up.
-
Under
OS Settings, set the
Host Name Selection to
Auto-Generate,
Specify at Deployment Time, or
Reverse DNS Lookup.
-
If you choose
Specify at Deployment, provide a name for the host in the
Host Name field. If you choose
Auto-Generate, specify a template for the name in the
Host Name Template field.
For an existing resource group that was not deployed by
PowerFlex Manager, the
Host Name Selection option is automatically set to
Specify at Deployment Time and you must type the hostname.
-
If you are adding a node to a hyperconverged resource group, specify the
Host Name Selection under
SVM OS Settings and provide details about the hostname, as you did for the
OS Settings.
-
In the
IP Source box, provide an IP address. For an existing resource group that was not deployed with
PowerFlex Manager, the default choice is
User Entered IP and the IP settings for each network default to
Manual Entry. However, you can change the setting to
PowerFlex Manager Selected IP.
If the
Multi-Network Selection option is selected and the IP source is
PowerFlex Manager Selected IP, the IPs are assigned sequentially from all the networks of that type. If an IP cannot be assigned from any of the multiple networks of the selected type, an error is displayed. If the IP source is
User Entered IP, a generic name is displayed for the IP Source setting. For example: "PowerFlex Management IP Source".
If multi networking is not enabled and the IP source is
User Entered IP, the name of the network is displayed as on the
Network Settings page. If the selected IP Source setting is of
Manual Entry type, the IP you entered is validated against all the networks of the selected type. An error is displayed when the IP is not validated in one of the networks.
Under
Hardware Settings, the
Target Boot Device option is automatically set to
Use Local Flash Storage for Dell PowerFlex for an existing hyperconverged or compute-only resource group that was not deployed by
PowerFlex Manager.
-
Under
Hardware Settings, in the
Node Source box, select
Node Pool or
Manual Entry.
For an existing resource group that was not deployed by
PowerFlex Manager, the node source defaults to
Manual Entry, but you can change it to
Node Pool.
-
In the
Node Pool box, select the node pool. Alternatively, if you chose
Manual Entry, select the specific node in the
Choose Node box.
You can view all user-defined node pools and the global pool. Standard users can see only the pools for which they have permission.
For an existing resource group that was not deployed by
PowerFlex Manager, the
Node Pool defaults to
Global.
- Under
PowerFlex Settings, specify the
Fault Set for a node:
- Select
PowerFlex Manager Selected Fault Set to have
PowerFlex Manager choose the fault set name based on the template settings.
- Select
fault-set-name to choose one of the fault sets in the resource group.
You can add nodes within a fault set, but
PowerFlex Manager does not allow you to add a new fault set within the same resource group. To add a new fault set, you must deploy a separate resource group with settings for the fault set you want to create.
-
Click
Next.
-
Review the
Summary page and click
Finish.
If the node you are adding has a different type of disk than the base deployment,
PowerFlex Manager displays a banner at the top of the
Summary page to inform you of the different disk types. You can still complete the node expansion. However, your resource group may have suboptimal performance.
Based on the component type, the required settings and properties are displayed automatically and can be edited as permitted for a node expansion.
