  • Motherboard/BIOS/System firmware
    Begining Data Ontap 8.0, minimum BIOS release required enables automatic BIOS updates. Therefore, no need worry about upgrading BIOS from 8.x. After minimum version is running, subsequent updates take place automatically during the boot sequence whenever Data ONTAP detects a version resident on the boot device is more recent than the running version.

upgrade NetApp disk and shelf firmware
http://indiawebsearch.com/content/how-to-upgrade-disk-shelf-firmware-on-a-netapp-filer

This article provides step by step instructions on how to upgrade the Shelf Firmware on a NetApp Filer running Data OnTap version 7.2. The Filer has four storage shelves which need their firmware to be upgraded.

We would be using CIFS to map a drive to the C$ of the Filer from a Windows machine. You can do the same using NFS by mounting the root volume of the Filer on a Unix client

In our case, we would use Filer1 as the name of the filer on which we need to upgrade the Disk Shelf Firmware.
  • Download the latest Shelf Firmware as a zip file from NetApps NOW site
  • Unzip the contents to a temporary folder e.g.; C:\temp\FilerShelfFirmware
  • Map a drive to the C$ share of Filer1 e.g. X:\
  • Copy the contents of C:\temp\FilerShelfFirmware to X:\etc\shelf_fw
  • Logon to the consoles of Filer1 using Putty
  • Give the command “Priv set advanced” to enter advanced mode
  • Check the current shelf firmware version by typing “sysconfig –v” in the output look for following lines, it shows the firmware version to be 35
    Shelf 1: AT-FCX Firmware rev. AT-FCX A: 35 AT-FCX B: 35
Shelf 2: AT-FCX Firmware rev. AT-FCX A: 35 AT-FCX B: 35
Shelf 3: AT-FCX Firmware rev. AT-FCX A: 35 AT-FCX B: 35
Shelf 4: AT-FCX Firmware rev. AT-FCX A: 35 AT-FCX B: 35
  • Type “storage download shelf” to update firmware on both filers
  • Wait until you get the following output, it could take 70 seconds per shelf x 4 shelves so close to about 5 minutes:
    Tue Dec 30 12:17:42 PST [sfu.downloadSuccess:info]: [storage download shelf]: Firmware file AT-FCX.3700.SFW downloaded on 0b.shelf4.
Tue Dec 30 12:17:42 PST [sfu.downloadSuccess:info]: [storage download shelf]: Firmware file AT-FCX.3700.SFW downloaded on 0b.shelf3.
Tue Dec 30 12:17:42 PST [sfu.downloadSuccess:info]: [storage download shelf]: Firmware file AT-FCX.3700.SFW downloaded on 0b.shelf2.
Tue Dec 30 12:17:42 PST [sfu.downloadSuccess:info]: [storage download shelf]: Firmware file AT-FCX.3700.SFW downloaded on 0b.shelf1.
Tue Dec 30 12:17:42 PST [sfu.downloadSummary:info]: Shelf firmware updated on 4 shelves
  • Check the new shelf firmware version by typing “sysconfig –v” it should now say 37 instead of 35

The following procedure describes how to upgrade the disk firmware on a NetApp Filer running Data OnTap version 7.2

The first step before upgrading the firmware is to check if the correct disk qualification packages are present on the filer. This determined by checking the datecode on the qual_devices_v3 file. Do the following to check the datecode


  • Log on to Filer Console using Putty
  • Give the following command: “rdfile /etc/qual_devices_v3”
The command would have outputted a lot of information, what we are interested in is the header, you might have to enable buffer logging in Putty to look at the buffer output or scroll back in Putty. We are looking for the datecode output in the header which looks like: 
#########
# This file is auto generated by the script file.
# Copyright (c) 2000 Network Appliance, Inc.
# All rights reserved. #
# Datecode: 20080807
Then we need to install the “Disk Qualification Package” else skip to section for Downloading and installing Disk Firmware Instructions for downloading and installing the Disk Qualification Package
  • Download the Disk Qualification Package as a zip file from: http://now.netapp.com/NOW/download/tools/diskqual/ and copy it to a temporary location on your C: drive e.g. C:\temp\FilerDiskFirmware\DiskQualificationPackage
  • Map a drive to the C$ share of Filer e.g. Q:\
  • Extract the files from the zip archive to the \etc directory on the Filer, e.g. Q:\etc
  • Wait 5 minutes for the system to process the newly installed Disk Qualification Packages.
Instructions for Downloading and Installing Disk Firmware
  • Go to http://now.netapp.com/NOW/download/tools/diskfw/ and click on the link that says “Download All Current Disk Firmware”
  • On the next page, click on the “Download Zip” button and save the zip file to a temporary location on your C: drive, e.g. C:\Temp\FilerDiskFirmware\all.zip
  • Extract the contents of the zip file to the /etc/disk_fw directory of the FILER e.g Q:\etc\disk_fw
  • Check that the following option is enabled on the filer by giving the command:
    “options raid.background_disk_fw_update.enable” it should return options raid.background_disk_fw_update.enable on . If its not on, turn it on
  • The filer should automatically detect that there is new disk firmware and do the upgrade, no reboot is necessary.

What triggers an update to Disk, Shelf, or ACP firmware in Data ONTAP 8 7-Mode
https://kb.netapp.com/support/index?page=content&actp=LIST&id=3013267
Disk Firmware:
Disk Firmware will be updated in one of the following three ways: 
In the Background:
This occurs when the following conditions are met:
  • options raid.background_disk_fw_update.enable is on
    -or-
    options raid.disk.background_fw_update.raid4.enable is on (where applicable)
  • Newer firmware for the disks present is placed in the /etc/disk_fw directory.
     
When manually triggered:

Data ONTAP and Disk Qualification Package (DQP)
Data ONTAP does not recognize a drive correctly.
Data ONTAP recognizes a 15k RPM drive as 10K RPM (default).
  1. Where does one install the DQP package?
    Data ONTAP looks for the qual_devices* file in the /etc directory of the root volume.
     
  2. Should one copy a specific version of the qual_devices file out of the archive or should one copy the contents of the entire DQP archive in the /etc folder? The minimum requirement is to install the version specific to the current Data ONTAP running on the storage system. The DQP file should be placed in the /etc folder in the root volume (/vol/vol0) on the filer.

    However, it is recommended to place all qual_devices* files (in the Disk Qualification Package) in the /etc folder to ensure smooth Data ONTAP upgrades in future.
     
  3. How does Data ONTAP determine if the DQP file has changed? And, how frequently does it check for changes in the installed DQP file? Data ONTAP reads the modification time of the DQP file to determine if it has changed or not. If the file modification time is different from the last time it checked, it processes it.
    Data ONTAP checks approximately every 5-10 minutes to see if the file modification time has changed.
     
  4. Does one have to reinstall DQP every time one adds a new drive or shelf?
    No, one does not have to install a new DQP every time one adds a new drive or shelf.
    Nonetheless, it is good practice to install the latest DQP, disk firmware, shelf firmware before the new hardware is added. The best time to do this is close to (before) adding new hardware.
     
  5. Does Data ONTAP load DQP after a reboot?
    Yes, it loads DQP as a part of the boot up process if it finds unqualified disks that are unknown to the kernel. This may take place a few minutes after the initial boot up and therefore a little delay is expected.
     
  6. Does Data ONTAP understand all versions of qual_device or does it understand only specific version depending upon the Data ONTAP revision?  
    Yes, specific revisions of Data ONTAP look for a particular revision of the /etc/qual_devices file as shown below. However, you still need to install/copy allqual_devices* files to the filer, regardless of what version you are on.

    qual_devices     For releases prior to 7.2.1
    qual_devices_v2  For releases 7.2.1, 7.2.2 and 7.2.3
    qual_devices_v2.copy Backup copy of v2 file
    qual_devices_v3  For releases 7.2.4 and later
    qual_devices_v3.copy Backup copy of v3 fi    le

    Note: If the Data ONTAP version is 7.2.4 and later, then refer the latest version of 7.3. For reference, see:
    Burt 270735
    Burt 234290
  7. How do I force Data ONTAP to re-read the Disk Qualification File?
    One can reboot the filer to have Data ONTAP re-read the qual_devices* files
CautionDO NOT edit the qual_devices* files or save the changes - any changes in the Qual Devices file will render the file meaningless and prevent Data ONTAP to read it successfully.
The latest qual_devices file is located at http://mysupport.netapp.com/NOW/download/tools/diskqual/
