Hi Dave,
>From my experience the answers to your question are as follows. Will the network be available throughout the execution of this script? yes - Does it ask for further confirmation? no - Does it reboot the box automatically, or will I need to do that myself? It will tell you at the end if a reboot is required... for bios it will be. - What *could* go wrong? I've done 20 x 1950's without any hitches... - Is it possible to revert to the previous BIOS if something goes wrong, and what would those steps be? During the flash process of the bios I'm pretty sure the script will test and ensure that the flash went in ok and if not it will revert back to old version this is normal practices with bios updates.

I've been following the steps outlined in this document: http://support.dell.com/support/systemsinfo/document.aspx?c=us&l=en&s=bs d&~file=/software/smdup/dup63/en/ug/html/3onliner.htm The outputs of `inventory_firmware` and `update_firmware` are as follows: [r...@molybdenum ~]# inventory_firmware Wait while we inventory system: System inventory: BIOS = a04 Primary Backplane = 1.00 PowerEdge Expandable RAID Controller 4e/Si Firmware = 521s System BIOS for PowerEdge 1850 = a04 BMC = 1.40 [r...@molybdenum ~]# update_firmware Running system inventory... Searching storage directory for available BIOS updates... Checking BIOS - a04 Available: dell_dup_componentid_00159 - a07 Found Update: dell_dup_componentid_00159 - a07 Checking Primary Backplane - 1.00 Available: dell_dup_componentid_03967 - 1.00 Did not find a newer package to install that meets all installation checks. Checking PowerEdge Expandable RAID Controller 4e/Si Firmware - 521s Available: pci_firmware(ven_0x1028_dev_0x0013_subven_0x1028_subdev_0x016c) - 5b2d Did not find a newer package to install that meets all installation checks. Checking System BIOS for PowerEdge 1850 - a04 Did not find a newer package to install that meets all installation checks. Checking BMC - 1.40 Available: dell_dup_componentid_05814 - 1.83 Found Update: dell_dup_componentid_05814 - 1.83 Found firmware which needs to be updated. Please run the program with the '--yes' switch to enable BIOS update. UPDATE NOT COMPLETED! For my piece of mind I'd like to know exactly what happens, and what I should be expecting when executing the `update_firmware --yes` command. >From what I can tell this is a point of no return. I'll be executing this upgrade remotely, but I do have the option of having someone go on site if something goes terribly wrong. Some specific questions I have: - Will the network be available throughout the execution of this script? - Does it ask for further confirmation? - Does it reboot the box automatically, or will I need to do that myself? - What *could* go wrong? - Is it possible to revert to the previous BIOS if something goes wrong, and what would those steps be? Thanks in advance, -Dave
