hdcrypt_conv – Encrypt/Decrypt logical and physical volumes.

Synopsis

This module is used to convert a logical or physical volume into an encrypted one and vice versa.

Requirements

The below requirements are needed on the host that executes this module.

• AIX >= 72X

• Python >= 2.7

Parameters

action (True, str, None)

Specifies which operation to perform on logical volumes. encrypt enables encryption and encrypts a logical volume; decrypt decrypts a logical volume;

device (True, dict, None)

Specifies the devices to encrypt or decrypt.

For action=encrypt lv/pv/vg will become encryption enabled if it is not already.

lv (optional, list, None)

Specify the logical volume(s) to be encrypted/decrypted.

pv (optional, list, None)

Specify the Physical volume(s) to be encrypted/decrypted.

vg (optional, list, None)

Specify the volume group(s) to be encrypted/decrypted.

except_lv (optional, list, None)

Specify the logical volume(s) to ignore when encrypting/decrypting.

password (True, str, None)

Specifies the password for encryption/decryption.

Used to set the intial password for encryption and provide authentication for decryption.

Password must also be encrypted.

Notes

Note

• You can refer to the IBM documentation for additional information on the commands used at https://www.ibm.com/docs/en/aix/7.2?topic=h-hdcryptmgr-command.

• Using this module on SAN disks might throw an error. It is a known error for AIX.
