I upgraded the kernel on db1100 (s5 standby master) and I suffered the issue we have seen at T216240: Reboot, upgrade firmware and kernel of db1096-db1106, db2071-db2092 - (the host not booting up), so we should try to upgrade BIOS and firmware, as we have seen that fixes those issues.
This host would require depooling before we can reboot it.
For now I have booted with the previous kernel: 4.9.88-1+deb9u1
Let me know when this can be done.

Great! Thank you. I have made a note on my calendar so the host will be depooled and off before 14:00UTC so once you arrive, it will be fully ready for you to upgrade.
@Cmjohnson are we still good for tomorrow at 14:00 UTC? I will have the host depooled and off for you before 14:00 UTC

@Cmjohnson db1100 is now OFF.
Once you are done leave it ON and will take care of MySQL and the rest of things
Thanks!
