Description Dave Berry 2007-11-29 20:39:45 UTC 
Description of problem:
multipath does not work due to a failure of scsi_id.   When /sbin/scsi_id is run
with -V(version) nothing is returned.  Also when /sbin/scsi_id -u -g -s
/block/sdq is run the wwid returned is longer than the wwid in RHEL 4.  This
prohibits multipath to set wwid in /etc/multipath.conf since the port of the SAN
is returned in the longer wwid.


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

udev-095-14.5
device-mapper-multipath-0.4.7-8

How reproducible:

very reporducible


Steps to Reproduce:
1.run /sbin/scsi_id -V
2.run /sbin/scsi_id -u -g -s /block/<device>
3.
  
Actual results:
nothing is returned for step 1
the long wwid is returned for step 2

Expected results:

-V should yield version numbers
the wwid should be limited to just the drive ID and not include the port on the SAN



Additional info:
Comment 1 Ben Marzinski 2007-12-11 18:35:15 UTC 
These are both scsi_id problems, not device-mapper-multipath problems. I'm
switching the component to udev, which provides /sbin/scsi_id.

commit 11678eff6a40b05d192be65146a66d5e1e8252ec
Comment 6 Harald Hoyer 2014-05-06 14:32:10 UTC 
# scsi_id -V
scsi_id version: 0.9

'-x' now adds a
ID_SERIAL_SHORT=
environment variable, which is most likely what you want.
