d. LUNs per target: 0
e. Enable LIP reset: No
f. Enable LIP full login: No
g. Enable target reset: Yes
h. Login retrycount: 20 (minimum)
i. Port down retrycount: 20 (minimum)
j. Driver load RISC code: Enabled
k. Enable database updates: No

11.Select one of the following options:
a. 0: Loop only
b. 1: Point-to-point (preferred setting)
c. 2: Loop preferred (If you cannot use arbitrated loop, then default to
point-to-point)
d. 3: Point-to point, otherwise loop (If you cannot use point-to-point, default
to arbitrated loop).
Note: In a clustering environment, set Enable LIP full login to Yes.
Note: The Enable LIP reset, Enable LIP full logon, and Enable target reset
parameters control the behavior of the adapter when Windows NT tries to do a
SCSI bus reset. You must perform a target reset to make cluster failovers
work. Use the SCSI bus device reset option to clear SCSI reservations.
