Looks like you are logged into standby Nexus1010. The VSB deployed on standby Nexus1010 is either stuck or the serial port. I suspect serial port stuck.
How to recover:
Log on to active Nexus1010 and log on to VSB on active Nexus1010 deployed in HA to check the ha staus.
Shut VSB on standby Nexus1010 and power on again to see if that helps to recover.
