Im sorry, Ive not seen this error before and feel it will take log analysis to determine the issue. The account team might have options to get support engaged

Hi Ankur

I noticed that Director-A is not listing or showing it's ports when i executed below cmd, However i can see FE and BE ports list on Director-B 

VPlexcli:/engines/engine-1-1/directors/director-1-1-A/hardware/ports>

And also when i checked uptime,i can see uptime only for Director-B,but for Director-A it's show blank 

VPlexcli:/engines/engine-1-1/directors/director-1-1-A/hardware/ports> uptime
Director director-1-1-B: 1794 days, 12 hours, 55 minutes, 15 seconds.
Director director-1-1-A: -

So i m thinking if reboot of Director-A might help us to fix the issue .

Can some one please suggest or advise if reboot is only option or any other way ?

Thanks
