Dell PowerFlex Appliance with PowerFlex 4.x Administration Guide

Configure settings of an existing NAS server

Select the NAS server name to get to the details for a specific server. You can add, modify, and delete NAS server settings from the NAS server details page.

The following rules apply to changing NAS server settings:

• You cannot disable multiprotocol file sharing for a NAS server once a file system is created on that NAS server.
• You cannot disable DNS for:
  • NAS servers that support multiprotocol file sharing.
  • NAS servers that support SMB file sharing and that are joined to an Active Directory (AD).
• To reconfigure a NAS server that supports SMB-only or NFS-only file systems so that it supports multiprotocol (both types of file systems simultaneously), first enable a UNIX Directory Service and DNS server for that NAS server.
• If you choose to change from an AD realm to a custom realm after the NAS server is successfully created with Secure NFS you will not be able to create any NFS exports until you preform the following operations:
  1. Create a keytab file.
  2. Remove the AD realm from the NAS server.
  3. Enter the username and password for the AD server.
  4. Enter the custom realm.
  5. Upload the keytab file.
