Red Hat Bugzilla – Bug 405021
scsi_id fails to show version info and proper wwids for multipath
Last modified: 2014-09-15 20:18:21 EDT
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):
Steps to Reproduce:
1.run /sbin/scsi_id -V
2.run /sbin/scsi_id -u -g -s /block/<device>
nothing is returned for step 1
the long wwid is returned for step 2
-V should yield version numbers
the wwid should be limited to just the drive ID and not include the port on the SAN
These are both scsi_id problems, not device-mapper-multipath problems. I'm
switching the component to udev, which provides /sbin/scsi_id.
# scsi_id -V
scsi_id version: 0.9
'-x' now adds a
environment variable, which is most likely what you want.
