Installing a Service Pack to Update the FluidFS Software
NOTE:
• Installing a service pack causes the NAS controllers to reboot during the installation process.
This might cause interruptions in CIFS client connections. In addition, active NDMP jobs are
terminated. Therefore, Dell recommends scheduling a maintenance window to perform service
pack installations.
• Contact Dell Technical Support Services to obtain service packs. Do not modify the service pack
filename.
• Ensure that all NAS controllers are powered on and their State is Formatted (the State is
displayed in the Hardware\NAS Appliances view). You cannot update the FluidFS software if a
NAS controller is down or detached.
• The FluidFS cluster FTP server must be enabled.
WARNING: The service pack installation process is irreversible. The FluidFS cluster cannot be
reverted back to a previous version once updated.
You can upload and install the service pack upgrade file to your FLuidFS system using the CLI or the web
UI.
To upload and install the service pack upgrade file using the CLI:
Use an FTP client to upload the service pack file to the FluidFS cluster FTP server at:
ftp://<FluidFS_administrator_user_name>@<client_VIP_or_name>:44421/ servicepack/
The file must be transferred using binary mode.
For example, the following command sequence can be used on a Windows command prompt:
