However, you can detach and attach a single NAS controller to a NAS cluster if you need to replace a NAS controller. NOTE: The first time you configure a NAS cluster, you are asked to accept an End-User License Agreement (EULA). You cannot configure the NAS cluster unless you accept the EULA. Resolve a Failed NAS Configuration If a configure NAS cluster operation fails, you can consider one of the solutions described in the following sections. If you cannot correct the problem, contact your customer support representative. If an operation fails during a NAS cluster configuration, Group Manager gives you the opportunity to correct the problem. You can then click Retry to retry the failed operation and resume the NAS cluster configuration. In addition, some configuration problems can be ignored. When they occur, Group Manager displays a message indicating the problem. You can then click Continue to resume the NAS cluster configuration without retrying the failed operation. See your NAS appliance hardware documentation for information about determining hardware status and correct the problem using the following procedures. Member Configuration Failure Description: You successfully discovered the NAS controllers, specified the NAS cluster configuration, and started the configuration operation, but the NAS controller configuration fails. Verify that: • NAS controllers' network ports are correctly connected to the proper client and SAN networks. • Make sure that you are the only PS Series group administrator trying to configure the NAS controllers into a NAS cluster. Click Retry. If the NAS controller configuration fails again, contact your customer support representative. Network Configuration Failure Description: Failure occurs during SAN or client network configuration. Verify that: • Network requirements are met: - Enable jumbo frames on the switch ports used for the internal and SAN networks. - Enable flow control on the same ports. • NAS controllers are correctly connected to the appropriate switch stack (SAN and IPMI ports are connected to the SAN switch stack, and client ports are connected to the client switch stack). • No duplicate IP addresses are in the network configuration. The IP addresses used in the NAS configuration and the group configuration must be unique in the network. If an IP address used in the NAS cluster is also used elsewhere, change the IP address where it is used outside of the NAS cluster. Click Change Configuration. Depending on the type of configuration that failed, you will see one of the following pages: 174 NAS Cluster Operations
