Use the ExpressNAV interface
The ATTO Technology ExpressNAV, a browser-
based configuration tool, allows you to map
devices to the SCSI ports using a web-based GUI.
See
ExpressNAV provides web-based interface
on page 19.
To map devices automatically with ExpressNAV
1
From the ExpressNAV main menu, click on the
Mapping menu item on the left side of the
screen.
Multiple target mode
Multiple Target Mode breaks the single iSCSI
node of the iPBridge and replaces it with a much
more configurable mapping scheme. This new
mapping scheme allows you to segregate storage
into different iSCSI nodes within the iPBridge,
with each iSCSI target having its own set of
access criteria.
For example, if you have two servers and a library
with four tapes and a media changer, the default
mapping would provide both servers access to all
tapes and the media changer (single target mode).
If you configured multiple target mode, you
would be able to map some devices to one server
and other devices to the other server, requiring
separate usernames and passwords for access.
CAUTION
CAUTION
If actual storage is mapped to more than
one iSCSI target and a server has
authorization for both targets, the server
could show duplicate storage without any
warning to the user.
If multiple target mode is enabled, the
