Cannot mount a USB key or disk device media to an ESXi/ESX host (1036340)

  • 89 Ratings

Symptoms

Connecting a USB key or disk device media to the ESXi/ESX host fails.

Note: For additional symptoms and log entries, see the Additional Information section.

Purpose

Restart the usbarbitrator service,  if you are unable to connect USB key or disk device media to an ESX/ESXi host.

Cause

This issue occurs because the usbarbitrator service has claimed the device to make it available for passthrough to virtual machines. You need to enable SSH / PuTTY for the host.

Resolution

To resolve this issue,  restart the usbarbitrator service:
  1. Run this command to stop the usbarbitrator service:

    /etc/init.d/usbarbitrator stop

  2. Disconnect and reconnect the USB key or disk device media. The device is automatically mounted under /vmfs/volumes/NO NAME/.
  3. After using the device, start the usbarbitrator service by running this command:

    /etc/init.d/usbarbitrator start

Additional Information

You experience these additional symptoms:
  • This issue occurs when the USB key or disk device media is formatted with a FAT16 partition and is of maximum size 2 GB.
  • The USB key or disk device media appears under lsusb but does not mount correctly.
Note:
  • ESXi does not support NTFS formatted devices.
  • You may want to connect a USB key or a disk device media to the ESXi/ESX host to copy data to it from the host. For example, to gather the vm-support bundle from the host when the host has lost the network connectivity.
