Verifying file system operation
1. Use the show device d command to list the devices:
Example
$ show device dg
NOTE: Use the show device/full dga100 command to show the path information for
the device:
Example:
$ show device/full $1$dga100:
Disk $1$DGA100: (NODE01), device type HP OPEN-V, is online, file-oriented
device, shareable, device has multiple I/O paths, served to cluster via MSCP
Server, error logging is enabled.

2. Create a test user directory:
Example
$ create/directory $1$dga100:[user]
This command creates a user directory name USER at the top level of the newly added volume
$1$DGA100.
3. Change to the new directory:
Example
$ set default
$1$dga100:[user]
4. Verify that this directory exists:
Example
$ show default
$1$dga100:[user]
If the user directory does not exist, OpenVMS returns an error.
5. Create a test user file:
Example
$ create test.txt
this is a line of text for the test file test.txt
[Control-Z]
The create command creates a file with data entered from the terminal. Control-z terminates
the data input.
6. Verify whether the file is created:
Example
