Dell EqualLogic PS6210XS Updating Firmware for EqualLogic PS Series Storage Ar - Page 19

6 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 firmware version that is not compatible with the corresponding FS Series appliance firmware 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 firmware version 3.0, any account with group administrator permissions can update array firmware. Before you update your NAS controllers to the latest version of FS Series firmware, you must first update all the storage arrays in the EqualLogic group to the corresponding PS Series firmware version. See PS Series Array and FS Series Appliance Compatibilityfor information about the latest FS and PS series firmware versions. • Before updating your FS series firmware: - 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 firmware on the NAS controllers on a Dell EqualLogic FS Series appliance. Before updating the firmware, note the following restrictions: • You must have the password for an account that has administrator privileges to update the NAS controller firmware. • You cannot update the NAS controller firmware if a NAS controller is down or detached, or if the NAS service is stopped. • Dell recommends updating the NAS firmware 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 firmware update, ensure that: • Replication partnership protocol is at version 3 or later • NFS export netmask is in prefix format (in the range 1-31) • All storage arrays in the EqualLogic group have been updated to the corresponding PS Series firmware version • File system is not in maintenance mode • SAN network is reachable from both ends (NAS → EQL and EQL → NAS) FS Series Appliances - Planning and Prerequisites 19
