Create a CHAP Account for Volume Scoped Target Volumes

CHAP (Challenge Handshake Authentication Protocol) users share a "secret." This CHAP secret is a word, phrase, or series of characters that both the array and the initiator know. The array will only allow access to those iSCSI initiators who respond with the correct secret.

  1. Go to Manage → Data Access → CHAP Accounts.
  2. Click + to open the New CHAP Account dialog box.
  3. Enter a name for the CHAP user.
    This is a convenient way to remember CHAP associations.
  4. Enter the CHAP secret.
    CHAP secrets must be between 12 and 16 characters, can not contain [ ] & ; or `, and are case sensitive. This must also be made available to the iSCSI initiator. The GUI runs over a secure connection, so the password is protected.
  5. Click OK.
  6. Use your iSCSI initiator software to add the CHAP secret to the iSCSI initiator configuration. The method used to add the CHAP secret to the iSCSI initiator is based on your OS and iSCSI management tool.
