Why I did it To upgrade SSD firmware in initramfs while rebooting from SONiC to SONiC and during NOS to SONiC migration. How I did it New option 'ssd-upgrader-part’ is introduced in grub command line, to indicate the partition and its filesystem type in which the SSD firmware updater is present. ‘ssd-upgrader-part’ syntax is ssd-upgrader-part=<partition>,<filesystem type>. Example: ssd-upgrader-part=/dev/sda8,ext4 A new initramfs script ‘ssd-upgrade’ is included in init-premount and it invokes the SSD firmware updater (ssd-fw-upgrade) present in the partition indicated by the boot option 'ssd-upgrader-part' How to verify it In SONiC, the SSD firmware updater is copied to “/host/” directory. Fast-reboot is to be initiated with the ‘-u’ option ([scripts/fast-reboot] Add option to include ssd-upgrader-part boot option with SONiC partition sonic-utilities#2150) After reboot, while booting into SONiC the SSD firmware updater will be executed in initramfs. |
