We are picking up from the first part of this post, HERE.

 

Enable/Configure/Disable iSCSI CHAP

Host > Manage Tab > Storage Adapters > select initiator > Targets tab > Authentication.

Note: I’m not using authentication or any ACL’s for my storage security as this is a lab environment. It is best practice to use some sort of ACL, CHAP security mechanism in production environments.

chap_auth1

chap_auth2

Note: There are 4 options to configure CHAP

  • Unidirectional CHAP required by target (Storage)
  • Unidirectional CHAP unless prohibited by target (Storage)
  • Unidirectional CHAP
  • Bidirectional CHAP

 

Determine Use Cases for Fiber Channel Zoning

  • Limit number of targets/LUNs presented to a host/initiator.
  • Network segmentation, similar to that of VLANs
  • Preferred paths in a fabric.
