On the UCS server, that should be set alarm sound during the fault state. Actually, I had the three UCS servers coexited on the one rack. It is diffcult for us to identify which server making the alarm sound is. Can I change the alarm sound to become the different sound?
The C-Series server are shipped with the raid controllers (LSI) that give you a warning when there is an alert with either hard drives, battery or raid controller. The beeping noise is more likely combing from this adapter. To my knowledge you can disable alarm tone but cannot be changed.
Do you have an IP address for CIMC (management) set up for these units? I do suggest to verify the status of the Virtual drives via GUI to find out where is the fault or hardware failure event. Also monitor the HDD LEDs.
This can give you a hint of the current issue:

The alarm tone can be disabled using the following command:
# MegaCli -AdpSetProp -AlarmSilence -aALL
You can also silence the alarm in the LSI MegaRAID BIOS Config Utility. However, be aware that this process requires a server reboot in order to access the WebBIOS. The alarm control is located in Controller Properties.
Usually, we can access ESXi Shell by pressing Alt+F1 from ESXi DCUI (Direct Console User Interface).
But on HyperFlex system, it just shows black window.
This is expected behavior because HyperFlex redirects ESXi Shell output to SoL...
