Description of problem:
Description of problem:

I have made two submissions for updating parameters for the store_hwe_ext macro 
call for the EMC CLARiiON in the last few months to the upstream multipath-
tools git head for libmultipath/hwtable.c.  The first submission establishes
immediate failback as the path group failback policy for the CLARiiON.  The 
second submission changes the product parameter string of the macro call to
"^[^LUN_Z]" from "*" in order to force multipath to recognize all CLARiiON 
logical units but the one which responds to a SCSI inquiry with the model 
string "LUN_Z           ".

This bugzilla is here just to make sure that the changes introduced by these 
submissions are included in the Update 3 release of RH 4.

Comment 1 Ed Goggin 2005-12-15 14:21:25 EST
My patch submitted upstream to the hwentry for CLARiiON for
multipath-tools/libmultipath/hwtable.c should have used a model string of
"^[^LUNZ]" instead of "^[^LUN_Z]".  NO UNDERSCORE!

Can you please integrate this change into the multipath-tools package for 
Update 3 of RHEL4?
Comment 2 Ed Goggin 2005-12-16 10:34:34 EST
More work is required to provide this functionality than I had previously 
thought necessary.  Because of this, the vendor field of the store_hwe_ext() 
macro for the EMC CLARiiON should be left at "*", that is, no further change is 
necessary for Update 3.
Comment 3 Ben Marzinski 2005-12-20 13:02:22 EST
I'm going leave this bug open as a placeholder for the generic clariion problem.
Comment 4 Alasdair Kergon 2006-03-08 11:53:13 EST
Need clarification of exactly what we should change, if anything, for U4.
