Dell PowerStore Configuring Volumes

Configure CHAP authentication

Challenge Handshake Authentication Protocol (CHAP) authenticates iSCSI initiators (hosts) and targets (volumes and snapshots) to expose iSCSI storage while ensuring a secure, standard storage protocol.

About this task

Without CHAP authentication, any host that is connected to the same IP network as the system iSCSI ports can read from and write to the system. If your system is on a public network, it is strongly recommended that you use CHAP authentication.

NOTE:If you plan to use CHAP authentication, you must set up and enable CHAP authentication before preparing volumes to receive data. If you prepare drives to receive data before you set up and enable CHAP authentication, you could lose access to the volumes.

For more information about CHAP authentication, including the benefits that it provides and details about implementation types, see the context-sensitive help entry in PowerStore Manager.

For in-depth information about how this feature works, see the PowerStore Security Configuration Guide.

Steps

  1. Select the Settings icon, and then select iSCSI CHAP in the Security section.
  2. Enable CHAP authentication.
    Additional configuration details are displayed.
  3. Select the type of CHAP implementation to use and click Apply.
