Before enabling RDL on the FlashArray, the array and the CryptoHub must establish a mutual trust relationship by validating their respective digitally signed certificates. Notes about certificates:
  • Certificates used on the FlashArray must be PEM-formatted (Base64-encoded).
  • Intermediary certificates are not supported for use with KMIP.
  • Using the Purity internal management certificate for KMIP configuration is not supported.
In the following sections, we will use the FlashArray Command Line Interface (CLI) to generate a FlashArray certificate and construct a Certificate Signing Request (CSR).

​
Generate a FlashArray certificate

Perform the following steps to generate a FlashArray certificate:
1
Use the following purecert create CLI command to create a self-signed certificate:
Shell
2
Display the certificate by using the following purecert list command: (Copy the displayed certificate for use in a later step.)
Shell

​
Construct a Certificate Signing Request (CSR)

Perform the following steps to construct a CSR:
1
Use the following purecert construct command to construct a CSR:
Shell
2
Copy the CSR that is displayed in the terminal and paste it into a file editor. Save the file with either the .pem or .csr extension. Then, move the file via SFTP or other means to the external storage device configured on the CryptoHub.
