1–Legacy vs. Open-iSCSI
Summary of Major Differences
1-6 IS0054604-00 A
12 Flash DDBs
with
Open-iSCSI
model driver
Not applicable The Open-iSCSI driver will
support existing Flash DDB
entries in the adapter.
iscsiadm has no control
over these sessions. Session
management of Flash DDB
entries is done by the driver
itself.
Note: iscsiadm
is not capable of
managing the
Flash target
entries.
Before migrating to
the Open-iSCSI
model, save this
DDB/target infor-
mation to node
records using
iscsiadm and
use the QLogic
application
a
to
delete Flash
entries apart from
boot targets before
the upgrade. Then,
upgrade to the
Open-iSCSI
model. Boot tar-
gets are always in
the Flash in both
models.
