Management: Firmware Downloads

A version number exists for each firmware file. The version number indicates 

whether the firmware is a major version or a minor version. You can use the 

Enterprise Management Window (EMW) to download and activate both the 

major firmware versions and the minor firmware versions. You can use the 

Array Management Window (AMW) to download and activate only the 

minor firmware versions.

Firmware versions are of the format aa.bb.cc.dd. Where aa is the major 

firmware version. bb.cc.dd is the minor firmware version. Depending on which one 

changes, firmware can be updated from EMW and AMW or only EMW.

You can activate the files immediately or wait until a more convenient time. 

You might want to activate the firmware or NVSRAM files at a later time 

because of these reasons:

• Time of day—Activating the firmware and the NVSRAM can take a long 

time, so you can wait until I/O loads are lighter. The RAID controller 

modules goes offline briefly to load the new firmware.

•

Type of package—You might want to test the new firmware on one storage 

array before loading the files onto other storage arrays. 

The ability to download both files and activate them later depends on the 

type of RAID controller module in the storage array. 

You can use the command line interface to download and activate the 

firmware to several storage arrays by using a script. Refer to the PowerVault 

Modular Disk Storage Manager online help topics for more information on the 

command line interface.
