Considerations for Nimble Storage When CHAP Authentication is enabled

You can backup hardware snapshot when Nimble storage has CHAP authentication enabled.

Note: CHAP Authentication is not supported on ESXi 5.0 because that version of ESXi does not have SQLite.

You need to complete the following prerequisites:

Prerequisites

Important: The prerequisites apply only if you want the Host-based agentless backup job to use SAN as the transport mode.

• Enable SSH on ESXi where Nimble storage is configured with CHAP authentication.
• Verify if the Proxy machine has the iscsicli command line interface required to configure iSCSI target devices.
• Set the execution policy to RemoteSigned on Proxy machine, to run the Powershell scripts. Use the following command:
• Set-ExecutionPolicy RemoteSigned
• Save ESXi credentials through a Powershell script for which the Nimble storage is configured with CHAP authentication.
• Follow these steps to save the ESXi credentials:
• Execute "StoreESXCredentials.ps1" Powershell script from Powershell on Proxy.
• You are prompted to enter details about IP, username, and Password.
• Enter all the three parameters.
• The credentials are stored in a CSV file "ESXCredentials.csv" and the password is encrypted.
• To locate the Powershell script, follow these steps:
• Log into the proxy machine and open the Powershell.
• Navigate to the following directory:
• Note: The path changes based on the installation directory.
• C:\Program Files\Arcserve\Unified Data Protection\Engine\BIN
• Run the Powershell script as given below:
• PS C:\Program Files\Arcserve\Unified Data Protection\Engine\BIN> .\StoreESXCredentials.ps1
