mrhsm sopin

Changes the security officer PIN (SO PIN).

Use the mrhsm sopin to change the SO PIN, which is used by the cluster administrator to perform PKCS#11 file or KMIP store modifications.

Syntax

# mrhsm sopin
    [ -oldsopin <PIN> ] 
    [ -newsopin <PIN> ]

The mrhsm sopin can be called with or without the -oldsopin <PIN> or -newsopin <PIN> parameters. If either parameter is not used while issuing the mrhsm sopin command, the system prompts you to specify the old or new SO PIN accordingly.

The PIN you specify can be 4-255 characters. All characters are allowed, including combinations of alphabetic, numeric, and special characters.

See About the SO PIN for more information.

Parameters

oldsopin: The -oldsopin <PIN> parameter requires you to specify the current SO PIN.

newsopin: The -newsopin <PIN> parameter assigns a new SO PIN.

Example

# mrhsm sopin
Current SO PIN: ****
Enter new SO PIN (4-255 characters): ****
Please reenter new SO PIN: ****
New SO PIN is set successfully
