The HSM becomes locked (no longer operational) if you change the SO password, restart the appliance without saving the configuration, and make three unsuccessful attempts to change the password. This is a security measure for preventing unauthorized access attempts and changes to the HSM settings.
If the HSM is locked, you must reset the HSM and restart the appliance to restore the default passwords. You can then use the default passwords to access the HSM and configure it with new passwords. When finished, you must save the configuration and restart the appliance.
At the command prompt, type the following commands to reset and re-initialize a locked HSM:
reset fips reboot -warm set fips -initHSM Level-2 newsopin123 sopin123 userpin123 -hsmLabel NSFIPS saveconfig reboot -warm
