Administrator Guide

• NAS controllers are correctly connected to the appropriate switch stack (that is internal, SAN, and IPMI ports are connected to
one switch stack, and client ports are connected to the client switch stack).
• No duplicate IP addresses are in the network conguration. The IP addresses used in the NAS conguration and the group
conguration 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.
Change the invalid conguration parameters. Clicking OK will automatically retry the specied conguration. The controller statuses
are reset to in progress and the red Xs are cleared from the display. If the retry operation was successful, the status shows success.
Or, you can click Retry. If the network conguration fails again, contact your service representative.
The group remains operational during the NAS cluster conguration. When the conguration succeeds, the progress window displays
a success message.
NOTE: During the NAS cluster conguration, you might see the following message:
Status of 0 is failed. Status of 1 is failed.
You can disregard this message.
Resolve a Failed NAS Conguration
If a congure 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 conguration, 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 conguration.
In addition, some conguration 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 conguration 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 Conguration Failure
Description: You successfully discovered the NAS controllers, specied the NAS cluster conguration, and started the conguration
operation, but the NAS controller conguration 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 congure the NAS controllers into a NAS cluster.
Click Retry. If the NAS controller conguration fails again, contact your customer support representative.
Network Conguration Failure
Description: Failure occurs during SAN or client network conguration.
Verify that:
• Network requirements are met:
– Enable jumbo frames on the switch ports used for the internal and SAN networks.
– Enable ow 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 conguration. The IP addresses used in the NAS conguration and the group
conguration 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 Conguration.
Depending on the type of conguration that failed, you will see one of the following pages:
