7. For each client network, verify the following settings for the NAS cluster, and click Auto ll:
• VLAN tagging
• IP address
• Netmask
• Default gateway
8. Click Auto ll to populate the table with NAS controller IP addresses, or type the addresses.
NOTE:
• The Auto Fill option bases new addresses on the rst NAS cluster IP address. This approach results in duplicate
addresses if any of the new addresses are already used on the network. You might want to specify IP addresses
individually to avoid duplicate addresses.
• Repeat this procedure for each congured client network. You will not be able to proceed until the information is
lled in for each client network.
9. Click Next. The SAN Network tab opens.
10. Verify the following SAN network information:
• Group IP address
• NAS cluster management IP address
• Netmask
11. Click Auto ll to populate the table with IP addresses for the SAN network, or type the addresses.
NOTE: The Auto Fill option bases new addresses on the rst NAS cluster IP address. This approach results in
duplicate addresses if any of the new addresses are already used on the network. You might want to specify IP
addresses individually to avoid duplicate addresses.
12. Click Next. The Summary tab opens.
13. In the Summary tab, either:
• Click the Copy link and save the summary information in a text le.
• Click Back to return to a previous page to verify the NAS controller information.
• Click Finish to add the NAS controller pair.
About Replacing a NAS Controller with Detach and Attach
In rare cases, you must remove a NAS controller from a NAS cluster and replace it with a dierent NAS controller. For example, you
might need to replace a malfunctioning NAS controller.
You can remove a NAS controller from a NAS cluster without aecting data availability by detaching the controller. After you detach
the controller, it resets to its factory defaults and powers o, if possible.
While a NAS controller is detached from the NAS cluster, SMB shares and NFS exports remain available. Most NAS cluster
conguration changes are not allowed while a NAS controller is detached.
To resume full NAS cluster functionality, you must attach a functioning NAS controller to the service. After the new controller is
attached, it inherits the NAS cluster conguration settings of the original NAS controller.
NOTE: Detach a NAS controller only under the direction of your customer support representative and only when you are
replacing that NAS controller.
Some NAS controller maintenance operations do not aect NAS controller operation (for example, replacing a hot-swappable
power supply). Other NAS controller maintenance operations require you to cleanly shut down the NAS controller, perform the
maintenance, and then restart the NAS controller. See your hardware documentation.
Detach a NAS Controller
To replace a malfunctioning NAS controller without aecting data availability, you can detach the NAS controller and then attach a
functioning NAS controller. A detach operation should be used only to replace a NAS controller.
