Description Ben Woodard 2002-05-28 13:10:52 UTC
Description of Problem:
Evidently, the SCSI subsystem doesn't probe all of the luns for a particular
SCSI chain because if it did so on some hardware it would cause problems. So
there is a white list of cards which have been tested to allow all their luns to
be probed. We have a very high end card here which has been carefully tested and
 which does allow all the luns to be probed. We would like it added to the
white-list.


Version-Release number of selected component (if applicable): 2.4.18-3


How Reproducible: 100%

Here is a very simple one line patch which addes it:

Added; I assume the SPARSELUN flag is tested and that FORCELUN was not enough
