USB Automount

This chapter describes USB Automount configuration on NCS 1000.

USB Automount

The USB automount feature allows the user to read from or write files and folders onto the USB device without explicitly mounting it. The mounted USB device can be accessed as disk2: file system.

When a USB device is inserted in NCS 1002, it is automatically mounted in sysadmin-vm with Read and Write permissions and unmounted in XR by default. The USB device is automatically mounted in sysadmin-vm only when the file system of the USB device is FAT or FAT32.

In NCS 1001, the USB device is automatically mounted in both sysadmin-vm and XR.

The user must unmount the USB device from sysadmin-vm or XR before it is removed from NCS 1000. If the USB device must be mounted again after the device is unmounted but before removing the device, it can be done using the mount command.

The user can simultaneously mount the USB device in XR-vm and sysadmin-vm. The user must unmount the USB device from both sysadmin-vm and XR-vm before it is removed from NCS 1000.
