Managing Firmware Updates
Firmware is automatically updated on NAS controllers during service pack updates and after a failed NAS controller is replaced. After a
firmware update is complete, the NAS controller reboots. It is important that you do not remove a NAS controller when a firmware update
is in progress. Doing so corrupts the firmware. A firmware update is in progress if both the rear power-on LED and cache active/off-load
LED repeatedly blink amber 5 times and then blink green 5 times. If you connect a monitor to a NAS controller VGA port during a firmware
update, the following message is displayed: Executing firmware updates for TopHat system.
Update Firmware Using FTP
Use this procedure to update controllers to the latest version of FluidFS:
Steps
1. Open Windows File Explorer.
2. In the address bar, type ftp://Administrator@FLUIDFS-VIP:44421/servicepack and hit Enter.
a) Log in as Administrator, and enter the Administrator password.

Restoring the NAS Volume Configuration
Restoring the NAS volume configuration provides an effective way to restore the following NAS volume settings without having to
manually reconfigure them:
• SMB shares
• NFS exports
• Snapshot schedules
• Quota rules
This is useful in the following circumstances:
• After recovering a system
• After recovering a NAS volume
• When failing over to a replication target NAS volume
NAS Volume Configuration Backups
Whenever a change in the NAS volume's configuration is made, it is automatically saved in a format that allows you to restore it later. The
configuration is stored and encrypted in the .clusterConfig folder, which is located in the NAS volume's root folder. This folder can
be backed up, either individually, or with the NAS volume's user data, and later restored.
The configuration of a NAS volume can be restored on another NAS volume on the same system or on another system.
A NAS volume configuration backup can be made available to be restored using the following methods:
• The storage administrator can manually copy the .clusterConfig folder to the NAS volume from its backup or from another NAS
volume. When using a backup from another system, the restore operation works only if the saved configuration was taken from a
system using the same FluidFS version.
• The storage administrator can copy the .clusterConfig folder to the NAS volume from its backup or from another NAS volume
using an NDMP restore. When using a backup from another system, the restore operation works only if the saved configuration was
taken from a system using the same FluidFS version.
• The .clusterConfig folder is automatically copied to target NAS volumes during replication.
