Use the update option of the srv4 volume command to update a volume.
Example
srv4 volume test -update -url d:\mynewdata
modifies the existing volume 'test' to use the new root directory 'd:\mynewdata'.
Modify login information/read-only status
Use the '-username', '-domain' and '-password' options to modify the login information.
Use the '-readonly' option to set the volume as read-only or vice-versa.
Notes
•When the URL directory is changed, srv4 does NOT move the files - the existing data files in the volumes must have been moved previously.
•For the description of the volume command, see volume.
