To remove the hardware write-protection, repeat the above procedure, only set
the WRT_PROT value to 0.
You can verify that the device is write-protected while running the OpenVMS
operating system—when you issue the OpenVMS DCL command SHOW
DEVICE DI, a write-protected drive will show a device status of ‘‘Mounted
wrtlck’’. If you issue the OpenVMS command SHOW DEVICE/FULL, a write-
protected drive will be listed as ‘‘software write-locked’’.
Note
You cannot remove hardware write-protection using the OpenVMS
MOUNT utility.
