I am seeing problems on VMAX3 All Flash where I am seeing alert "Retention failed to run for Symmetrix XXXX within the last 24 hours"  This error is repeated every hour.  It appears this error has crept up since upgraded VMAX to the target code last month.   I open a support ticket and was told to log into vapp manager on mgmt-1 and reboot it.  However,  I don't know which ip mgmt-1 or mgmt-0.  I tried to get help via support chat and there were not able to answer the question.  I have logged into vapp(port 5480) but I couldn't determine anything.  Any idea where this information is kept?   I am concerned about rebooting the wrong one.
