Checking and changing the mode on an nShield 5s module

You must change the mode on the nShield HSM to perform certain maintenance and configuration tasks. This nShield HSM does not have a physical mode switch. Switch between modes using the nopclearfail utility.

Use the following commands to change the mode of a module:

Command Resulting mode

nopclearfail --maintenance |-M


nopclearfail --operational | -O


nopclearfail --initialization | -I


  1. Run the nopclearfail command specifying the module number and the new mode.

    When finished, the system responds with OK. This message is not confirmation that the module has changed mode.

  2. Confirm the new mode of the module by running the enquiry command.

    The mode line of the Module section displays the current mode.
