A factory MDS director has two supervisors. The install impact for the new system image reports that the upgrade is disruptive. What happens if the engineer continues with that image?
Select an answer to reveal the explanation.
Short Explanation
Two engines do not make a red light turn green. When the install impact says the system-image upgrade is disruptive, continuing it reloads the switch and Fibre Channel forwarding stops. A second supervisor is what makes a nondisruptive path possible, and this impact says you do not have that path.
Full Explanation
MDS can upgrade a dual-supervisor system without a traffic-stopping reload only when the impact analysis says the path is nondisruptive. A disruptive result means the target image is not an in-service upgrade from the running image, so proceeding reloads the switch and logins drop while it boots. The standby supervisor does not keep forwarding through an upgrade the impact already marked disruptive. An EPLD or other programmable-hardware update is a separate install. It is not what this system-image impact is describing, and continuing the system-image install does not leave that image untouched. Principal-switch priority and domain IDs are fabric-domain settings. A system-image upgrade does not renumber every VSAN. Caveat: if a later impact for a different target image says nondisruptive, that image can use the dual supervisors. This result does not. Operational check: read the impact line for this exact image again before you answer yes, and expect a disruptive install to log devices out of the fabric.
