Operating RZ- and RF-Series Disk Drives
Console Mode Write-Protect For RF-Series Drives
The console mode write-protect provides a more permanent
write-protection than the software write-protect. Once you
write-protect an RF-series drive from console mode, it remains
write-protected, regardless of the availability of the operating
system or if the system is powered down. You cannot remove a
console mode write-protection using the
mount command.
Consider write-protecting an RF-series drive from console mode
in the following situations:
• To write-protect an RF-series drive when the OpenVMS AXP
operating system is not available
• To ensure that an RF-series drive remains write-protected
under all circumstances
To write-protect an RF-series drive through console commands
entered at the console prompt (
>>>
), use the following
instructions:
1. Access the Diagnostic and Utility Program (DUP) driver for
the device you want to write-protect.
To access the DUP driver from console mode:
a. Invoke console mode by pressing the Halt button or
powering up the system with the Halt button pressed to
the in position.
Caution
Halting your system without following the shutdown
procedure described in your system software manuals
can result in loss of data.
