b. In the IP Address field, type an IP address for the NAS controller.
c. Click OK.
d. Repeat the preceding steps for each NAS controller.
e. 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.
f. Click Next.
7. (iSCSI only) To configure the IP addresses for SANb / eth31, use the Configure IP Addresses for NAS Controller iSCSI
HBAs page. This page displays the existing values that were configured during deployment. To use the existing values, click
Next. To change the values:
a. Select a NAS controller and click Edit Settings.
The Edit Controller IP Address dialog box opens.
b. In the IP Address field, type an IP address for the NAS controller.
c. Click OK.
d. Repeat the preceding steps for each NAS controller.
e. 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.
f. Click Next.
8. To verify connectivity between the FluidFS cluster and the Storage Center, use the Connectivity Report page. The NAS
controller ports must show the status as Up before you can complete the wizard. If you click Finish and the NAS controller
ports do not have the Up status, an error will be displayed.
● (iSCSI NAS appliances) When the Connectivity Report initially appears, iSCSI logins might still be occurring in the
background, causing some or all of the FluidFS cluster iSCSI initiators to show the status Not Found/Disconnected.
If you see this status, wait 30 seconds, then click Refresh to update the Connectivity Report. When the iSCSI logins are
complete and the Connectivity Report has been refreshed, the status for each FluidFS cluster iSCSI initiator shows as
Up.
● (Fibre Channel NAS appliances) When the Connectivity Report initially appears, the FluidFS cluster HBAs show the
status Not Found/Disconnected. You must record the WWNs and manually update fabric zoning on the Fibre
Channel switch. Then, click Refresh to update the Connectivity Report. When the zoning is configured correctly and the
Connectivity Report has been refreshed, the status for each FluidFS cluster HBA shows as Up.
9. Click Finish.
NOTE:
The Storage Center that was just added is not providing storage space to the FluidFS cluster yet. After adding
a Storage Center, you must expand the NAS pool to get the new Storage Center to provide block-level storage for the
NAS pool.
10. Expand the NAS pool.
When the expand NAS pool process is complete, the Storage Center tab will display both Storage Centers and the Volume
Status should show as Up.
Adding and Deleting NAS Appliances in a FluidFS Cluster
FluidFS supports up to four NAS appliances for each FluidFS cluster.
Add NAS Appliances to a FluidFS Cluster
You can add a NAS appliance (two NAS controllers) to a FluidFS cluster to increase processing power. Adding a NAS appliance
allows additional client connections and evenly redistributes client connections and FluidFS cluster operations among more NAS
controllers contributing their resources.
Prerequisites
● The additional NAS appliance is mounted in a rack and cabled, and the NAS controllers are in standby mode and powered on.
A NAS controller is on and in standby mode if the power LED is flashing green at around two flashes per second.
● NAS appliance service tags are recorded.
● New client VIP IP addresses are available to be added to the new NAS appliance. To ensure effective load balancing, use the
following recommendations to determine the number of client VIPs to define:
