We need to update the firmware on our switching stack and would like to temporarily disable the IPMI watchdog.
We are using the hardware IPMI watchdog on Proxmox VE v4.3, as follows:
Can I temporarily increase this to 600, to provide sufficient time for the maintenance?
Additional information on the switches:
The switch stack requires all members to have the same firmware. We are running active/backup bond interfaces interleaved on two stacked switches (Ceph on one and VM traffic on the other). This way the Ceph or VM traffic don't unnecessarily cross the stack uplinks, unless a primary interface fails.
We asked the vendor to provide details as to how we could upgrade the switches one at a time and they advised that we would need to break the stack, upgrade each unit and then re-assemble the stack. This sounds like more work and may lead to more complex problems than simply scheduling temporary downtime. We'll probably install a separate 10GbE SFP+ switch in the long run, as we don't require multi chassis IEEE 802.1AX (aka 802.1ad, aka LACP) to interface with the virtual hosts or routers.
