Management: Firmware Downloads 20715Management: Firmware DownloadsDownloading RAID Controller and NVSRAMPackagesA version number exists for each firmware file. The version number indicateswhether the firmware is a major version or a minor version. You can use theEnterprise Management Window (EMW) to download and activate both themajor firmware versions and the minor firmware versions. You can use theArray Management Window (AMW) to download and activate only theminor firmware versions.NOTE: Firmware versions are of the format aa.bb.cc.dd.Where, aa is the major firmware version and bb.cc.dd is the minor firmwareversion. Depending on which one changes, firmware can be updated from EMWand AMW or only EMW.You can activate the files immediately or wait until a more convenient time.You may want to activate the firmware or NVSRAM files at a later timebecause of these reasons:• Time of day—Activating the firmware and the NVSRAM can take a longtime, so you can wait until I/O loads are lighter. The RAID controllermodules are offline briefly to load the new firmware.• Type of package—You may want to test the new firmware on one storagearray before loading the files onto other storage arrays.The ability to download both files and activate them later depends on thetype of RAID controller module in the storage array.NOTE: You can use the command line interface to download and activate thefirmware to several storage arrays by using a script.
