CHAP authentication
The CHAP user name and password that you specify must conform to the following guidelines:
•
If you define an inbound user name and password on the storage system, you must use the same user name and password for outbound CHAP settings on the initiator.
•
If you also define an outbound user name and password on the storage system to enable bidirectional authentication, you must use the same user name and password for inbound CHAP settings on the initiator.
•
You cannot use the same user name and password for inbound and outbound settings on the storage system.
•
CHAP user names can be 1 to 128 bytes. A null user name is not allowed.
•
CHAP passwords (secrets) can be 1 to 512 bytes. Passwords can be hexadecimal values or strings. For hexadecimal values, enter the value with a prefix of “0x” or “0X”. A null password is not allowed.
