CHAP settings are 
applied using the QLogic

With CHAP support in 
iscsiadm, CHAP entries can 

now be added, deleted, and 
listed from the user space. 

Note: Before you 
migrate, delete all 
CHAP information 
from Flash using 
the QLogic applica-
tion

, and then 

update the same 
CHAP information 
in the respective 
node records using 
iscsiadm com-

mands.
When migration 
begins, any CHAP 
information in the 
Flash will be hon-
ored, but it must be 
updated in the 
node records using 
iscsiadm.
Open-iSCSI CHAP 
management is not 
supported in RHEL 
6.2 and SLES 11 
SP2. 
CTRL+Q options 
let you set unidi-
rectional and bidi-
rectional CHAP 
only for boot tar-
gets. In both mod-
els, CHAP 
information for boot 
targets is always 
stored in Flash.
