Editing an iSCSI server connection
You can edit the following fields for an iSCSI server connection:

Load balancing
•
CHAP options
You can also delete an iSCSI server connection from the management group. For more information,

CAUTION:
•
If you change the load balancing or CHAP options, you must log off and log back on to the
target in the iSCSI initiator for the changes to take effect.
•
Editing the iqn or CHAP server settings may interrupt access to volumes. If necessary, or if
the server is sensitive to disconnections, stop server access before editing a server.

log servers off and back on to the volumes.
This may entail stopping the applications, disconnecting them, reconnecting the applications
to the volumes, and then restarting them.
