You attempted to mount a device, but you do not have root authority or you are not a member of the system group.
You attempted to mount a directory over a regular file, for example:
```
mount Directory File
```
You tried to use a nonexistent file or directory as a mount point.
A device (for example, a diskette drive) to be mounted is either not ready or is write- protected.
You attempted to mount a file system that is already mounted.

Run the id command from the command line to ensure that you have the correct authority.
Ensure that the mount point that you specify for a directory is a directory, and the mount point for a file is a regular file.
Create the file or directory to be used as the mount point.
Ensure that the device is ready (for example, the diskette is in the drive) and is not write-protected.

This error message is displayed with the following text:

A device is already mounted or cannot be unmounted.



for one of the following reasons:

Using SMIT, you specified the name of a file system that has an active device mounted over it.
You used the unmount or umount command to unmount a file system that has an active device mounted over it.

Obtain the proper access permissions.
1. Select the SMIT Physical and Logical Storage--> File Systems--> Unmount a File System--> NAME of file system to unmount menu option.
2. Select List to display a list of available file systems.
3. Choose a file system to unmount.
4. Select Do to unmount the file system.

2. Use the umount or unmount command to unmount the file system.
Remove active devices before unmounting a file system.
1. Select the SMIT Physical and Logical Storage--> File Systems--> Unmount a File System--> NAME of file system to unmount menu option.
2. Select List to display a list of available file systems.
3. Select a file system to unmount.
4. Select Do to unmount the file system.

You tried to mount or unmount a file system that may be damaged.
You ran the ff or fsck command on a file system after modifying the /etc/filesystems file and specifying an incorrect device.
You attempted to run the fsck command on a cdrfs (CD-ROM) file system.

Run the fsck FileSystem command on the file system to check whether there are errors in the output.
1. If the fsck output displays errors, reboot the system from the boot media. Select the Maintenance option, then select Access a Root Volume Group.
2. After identifying the correct volume group, select Access this Volume Group and start a shell before mounting filesystems.
3. Run the fsck command on all the file systems, including the damaged one.
4. Enter exit after all the file systems are checked.
5. Shut down the system:
```
shutdown -Fr
```
Ensure that the device specified in the /etc/filesystems file is correct, or use SMIT to remove and then recreate the file system.
Check the /etc/filesystem file for the FileSystem stanza. If the vfs field is crdfs , do not run the fsck command.
