www.dell.com | support.dell.com Before You Begin Schedule system maintenance time with the customer and remind them that they may want to back up all files on the hard drives of the affected server modules. The customer may have mirroring from server module to server module or have a server module communicating with other server modules. Explain that if you bring a server module down for maintenance, errors may occur. This allows the customer to take the necessary steps to deconfigure their system before you begin maintenance. NOTE: Perform the upgrade on one server module at a time. Do not proceed to another server module until you have completed the upgrade on the current module. Determine the server module's hard-drive configuration. • If you do not know the configuration or if the server module has two hard drives and you do not know whether the mirroring function is enabled, see "Verifying the HardDrive Mirroring Mode." • If the server module has only one hard drive, see "Replacing the Server Module Board."
