Verify that the quorum disk is fast and reliable, too. Quorum-disk transitions should be
very rare, and latency should be typically low. If the transition count is high, the last
transition is recent, or the latency is high, you may want to choose a faster/more-reliable
quorum disk before you perform the upgrade. Select another disk by changing it on both
peers, one after the other.

CLI Maintenance Guide
verify the connection to the quorum disk (see
page 6-19
of the
CLI Network-Management
switch, not the switch where you will do the upgrade first. Any "Up" status, even if
the switch is not receiving heartbeats, is acceptable.
For example, the "prtlndA1k" is ready to take Active service during an upgrade:
