FS Series Appliances — Planning and Prerequisites
This section includes information that you should review before updating FS Series appliances.
NOTE:
• If you are running a rmware version that is not compatible with the corresponding FS Series appliance rmware version
listed in Table 2. Compatibility Matrix, the following operations are not supported:
– NAS reserve resize
– Adding an appliance
– Quota creation (allowed by the CLI)
– User mapping (allowed by the CLI)
– Forming a new cluster
– All new features added in later releases
• As of FS Series appliances rmware version 3.0, any account with group administrator permissions can update array
rmware. Before you update your NAS controllers to the latest version of FS Series rmware, you must rst update all the
storage arrays in the EqualLogic group to the corresponding PS Series rmware version. See PS Series Array and FS Series
Appliance Compatibilityfor information about the latest FS and PS series rmware versions.
• Before updating your FS series rmware:
– Ensure that your FS series NAS appliance is in a healthy state. If the appliance has any issues, or if you have questions
or concerns, contact Dell Technical Support for help.
– Make a backup copy of your data.
In some cases, you might have to update the rmware on the NAS controllers on a Dell EqualLogic FS Series appliance. Before
updating the rmware, note the following restrictions:
• You must have the password for an account that has administrator privileges to update the NAS controller rmware.
• You cannot update the NAS controller rmware if a NAS controller is down or detached, or if the NAS service is stopped.
• Dell recommends updating the NAS rmware during a scheduled maintenance, because it can take 30-45 minutes for the update
to complete.
• Because the NAS controllers are restarted during the update process, all Server Message Block (SMB) clients disconnect.
Although connections to the Network File System (NFS) shares will not disconnect, I/O to these shares will stop for several
minutes during the update. For these reasons, Dell suggests that you stop all I/O to the NAS cluster before the update.
FS Series Appliances Health Check
Before you begin: Make sure that the NAS controllers that you are updating have no current health problems. See the Dell
EqualLogic Group Manager CLI Reference Guide for detailed information about commands that you might need to run to validate
the health of your appliances.
For a successful rmware update, ensure that:
• Replication partnership protocol is at version 3 or later
• NFS export netmask is in prex format (in the range 1–31)
• All storage arrays in the EqualLogic group have been updated to the corresponding PS Series rmware version
• File system is not in maintenance mode
• SAN network is reachable from both ends (NAS → EQL and EQL → NAS)
