Problem:

NCP volume creation on OES 2.0 server is failing by giving error as "Volume NCP could not be created, error 22."

Solution:

You will be trying to create a NCP volume which was exiting before assuming you have removed the volume by deleting the path to which it was mounted.

E.G.: run ncpcon volume on the linux console, you will see both NSS and NCP volumes existing on that server. Assume there is a ncp volume by name the NCP existing.

path /ncp/ is mounted to NCP volume. (NCP is a volume name)
remove /ncp/ by running command rm -fr /ncp/

Now, if you run the ncpcon volume command, you will not be able to see NCP under volumes since the mount point is removed.

Since the volume name does not exists in the list, if you try to create a volume with the same name as NCP you will get the above error:

The solution is to remove the volume by running:

ncpcon remove volume <ncp volume name> 
command from the linux console. Once it deletes the volume successfully, try to create the same.

Please see the example for detailed info.

Example:

systst-ts-164:/ # ncpcon volume
... Executing " volume"

        SYS
