○ If client access to the FluidFS cluster is not through a router (in other words, a flat network), define one client VIP per
FluidFS cluster.
○ If clients access the FluidFS cluster through a router, define a client VIP for each client interface port per NAS controller.
● New NAS controller IP addresses are available to be added to the new NAS appliance. Verify that there are two additional IP
addresses available per NAS appliance.
About this task
For high availability reasons, you must add NAS appliances as NAS controller pairs. You cannot add a single NAS controller. Only
one NAS appliance can be added at a time up to a maximum of four NAS appliances (eight NAS controllers).
Adding a NAS appliance is a seamless operation that does not interrupt current FluidFS cluster operations. After the NAS
appliance is successfully added, new client connections are automatically distributed to all NAS controllers, ensuring that there is
efficient load balancing between all NAS controllers.
NOTE: Due to the complexity and precise timing required, schedule a maintenance window to add the NAS appliance(s).
Steps
1. (Directly cabled internal network only) If the FluidFS cluster contains a single NAS appliance, with a direct connection on the
internal network, re-cable the internal network as follows.
a. Cable the new NAS appliance(s) to the internal switch.
b. Remove just one of the internal cables from the original NAS appliance.
c. Connect a cable from each NAS controller port vacated in Step b to the internal switch.
d. Remove the second internal cable from the original NAS appliance.
e. Connect a cable from each NAS controller port vacated in Step d to the internal switch.
2. In the Storage view, select a FluidFS cluster.
3. Click the Hardware tab.
4. In the Hardware tab navigation pane, select Appliances.
5. In the right pane, click Add Appliances. The Add Appliances wizard appears and displays the Select Appliances to Add
page.
6. Select the NAS appliance to add to the FluidFS cluster.
a. In the top pane, select the NAS appliance.
b. Click Add Appliance. The selected NAS appliance is moved to the bottom pane.
c. ClickNext.
7. (iSCSI only) Complete the Configure IP Addresses for NAS Controller iSCSI HBAs page to configure the IP addresses
for SAN / eth30.
a. Select a NAS controller and click Edit Settings. The Edit Controller IP Address dialog box appears.
b. In the IP Address field, type an IP address for the NAS controller.
c. Click OK. Repeat the preceding steps for each NAS controller.
d. To specify a VLAN tag, type a VLAN tag in the VLAN Tag field. When a VLAN spans multiple switches, the VLAN tag is
used to specify to which ports and interfaces to send broadcast packets.
e. Click Next.
8. (iSCSI only) Complete the Configure IP Addresses for NAS Controller iSCSI HBAs page to configure the IP addresses
for SANb / eth31.
a. Select a NAS controller and click Edit Settings. The Edit Controller IP Address dialog box appears.
b. In the IP Address field, type an IP address for the NAS controller.
c. Click OK. Repeat the preceding steps for each NAS controller.
d. To specify a VLAN tag, type a VLAN tag in the VLAN Tag field. When a VLAN spans multiple switches, the VLAN tag is
used to specify to which ports and interfaces to send broadcast packets.
e. Click Next. The Configure Client Network page displays.
9. If needed, add additional client VIPs through which the clients will access SMB shares and NFS exports.
a. In the Virtual IP Addresses area, click Add. The Add Client IP Address dialog box appears.
b. In the IP Address field, type a client VIP IP address.
c. Click OK.
10. Add an IP address for each new NAS controller. Repeat the following steps for each NAS controller.
a. Select a NAS controller and click Edit Settings. The Edit Controller IP Address dialog box appears.
b. In the IP Address field, type an IP address for the NAS controller.
