continue to run in the background. You can view the installation progress using the File System tab→Maintenance →

Managing Firmware Updates
Firmware is automatically updated on NAS controllers during service pack updates and after a failed NAS controller is replaced. After
a rmware update is complete, the NAS controller reboots. It is important that you do not remove a NAS controller when a rmware
update is in progress. Doing so corrupts the rmware. A rmware update is in progress if both the rear power-on LED and cache
active/o-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 rmware update, the following message is displayed: Executing firmware updates for TopHat system.
Restoring the NAS Volume Conguration
Restoring the NAS volume conguration provides an eective way to restore the following NAS volume settings without having to
manually recongure 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 Conguration Backups
Whenever a change in the NAS volume's conguration is made, it is automatically saved in a format that allows you to restore it later.
The conguration 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 conguration of a NAS volume can be restored on another NAS volume on the same system or on another system.
A NAS volume conguration 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 conguration 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
conguration was taken from a system using the same FluidFS version.
• The .clusterConfig folder is automatically copied to target NAS volumes during replication.
Restore the NAS Volume Conguration
When you restore a NAS volume conguration, it overwrites and replaces the existing conguration. Clients that are connected to
the FluidFS cluster are disconnected. Clients will then automatically reconnect to the FluidFS cluster.
1. Ensure the .clusterConfig folder has been copied to the root folder of the NAS volume on which the NAS volume
conguration will be restored. One way to access the root folder of a NAS volume is to open Windows Explorer and in the
address bar type: \\<client_VIP_or_name>\C$\<NAS_volume>\.
2. In the Storage view, select a FluidFS cluster
3. Click the File System tab.
4. In the File System tab navigation pane, expand NAS Volumes and select a NAS volume.
