Description Flags
patch that whitelists IBM ESS none

Description Martin Peschke 2004-02-10 23:42:15 UTC 
Description of problem:
The IBM Enterprise Storage Server (aka Shark) has not been scanned
beyond LUN 0, although max_scsi_luns had been set appropriately in
/etc/modules.conf.

Version-Release number of selected component (if applicable):
2.4.21-9.EL

How reproducible:
100%

Steps to Reproduce:
1. Load zfcp driver with module parameter "map=" containing more than
one FCP device address mapping, which make scsi_mod scan entire busses.
2.
3.
  
Actual results:
cat /proc/scsi/scsi -> only LUN 0 was detected

Expected results:
All LUNs specified in zfcp's "map=" paramter should be detected in the
first place.

Additional info:
Manually triggering SCSI device detection by means of
add-single-device works for each LUN and points out the underlying issue.

patch that whitelists IBM ESS
Comment 2 Pete Zaitcev 2004-02-11 00:01:20 UTC 
The context is that we specifically asked IBM to whitelist ESS
in RHEL 3 (as opposed to enable sparse LUN scanning globally
in config-s390-generic) on Arjan's insistence.

Doug, do you want me to grab this?
Comment 4 Martin Peschke 2004-02-11 23:03:47 UTC 
Right, in the course of that discussion Pete's initial request sank
into oblivion. Mea culpa.
(Isn't anybody else at IBM testing this beast? :-\  )
