Adding a Storage Center to a FluidFS Cluster

The back-end storage for a FluidFS cluster can be provided by one or two Storage Centers.

1. In the Storage view, select a FluidFS cluster.
2. Click the Summary tab.
3. Click Actions→ Storage Centers→ Add Storage Centers.
   The Add Storage Center wizard starts and opens the Select Storage Centers (only supported Storage Centers shown) page.
4. Select the additional Storage Center to provide storage for the FluidFS cluster and then clickNext.
5. (iSCSI only) Select two fault domains on the Select iSCSI Fault Domains from Storage Center page and click Next.
6. (iSCSI only) To configure the IP addresses for SAN / eth30, 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:
   1. Select a NAS controller and click Edit Settings.
      The Edit Controller IP Address dialog box opens.
   2. In the IP Address field, type an IP address for the NAS controller.
   3. Click OK.
   4. Repeat the preceding steps for each NAS controller.
   5. 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.
   6. 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:
   1. Select a NAS controller and click Edit Settings.
      The Edit Controller IP Address dialog box opens.
   2. In the IP Address field, type an IP address for the NAS controller.
   3. Click OK.
   4. Repeat the preceding steps for each NAS controller.
   5. 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.
   6. 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.
