Procedure to upgrade the Disk firmware.

Note 1: Schedule the disk firmware update during times of minimal usage of the filer as this activity is intrusive to the normal processing of disk I/O.

Note 2: Since updating the disk firmware involves spinning the drive down and back up again, it is possible that a volume can become offline if upgrading 2 or more of the same drive types in the same RAID group. This is because when you upgrade disk firmware, you are upgrading the disk firmware of all the same drive types in parallel. When encountering a situation like this, it is best to schedule a maintenance window to upgrade the disk firmware for all disks.

Option #1 - Upgrade the Disk Firmware in the Background

1.        Check or set the raid.background_disk_fw_update option to on

To Check:         options raid.background_disk_fw_update.enable

To Set:              option raid.background_disk_fw_update.enable on

2.       Place the new disk firmware File into the /etc/disk_fw directory

The system will recognize the new available version and will non-disruptively upgrade all the disks requiring a firmware update to that new version in the background.

Option #2 – Upgrade the disk firmware during a system reboot

1. Check or set the raid.background_disk_fw_update option to OFF

To Check:         options raid.background_disk_fw_update.enable

To Set:              option raid.background_disk_fw_update.enable off

2. Place the new disk firmware File into the /etc/disk_fw directory

Schedule a time to perform a system reboot. Note that the reboot will take longer as the reboot process will be suspended while the disk firmware is upgraded. Once that is complete the system will continue booting into Data ONTAP.

Option #3 – Upgrade the disk firmware manually

1. Check or set the raid.background_disk_fw_update option to OFF

To Check:         options raid.background_disk_fw_update.enable

To Set:              option raid.background_disk_fw_update.enable off

                2. Place the new disk firmware file into the /etc/disk_fw directory

                3. Issue the disk_fw_update command

The above given are the three procedure for upgrading the disk firmware.
