RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

In "4.3. Configuration File Defaults", there are two mentions of the default options used for the "getuid_callout" field.

The document presently says:

  getuid_callout          "/sbin/scsi_id -g -u -s /block/%n"

However, this is no longer the case, and won't actually work.

The multipath.conf man page now says the default options are:

  "/lib/udev/scsi_id --whitelisted --device=/dev/%n"

(Which ironically won't work either, as the path to scsi_id on RHEL 6 is "/sbin/scsi_id".  The man page has the options correct, but the path wrong.)

The corrected version for the doc should be this:

  getuid_callout          "/sbin/scsi_id --whitelisted --device=/dev/%n"

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.

Double checked the path for scsi_id here on RHEL 6, and F13, and they both have:

$ ls -al /sbin/scsi_id 
lrwxrwxrwx. 1 root root 19 Apr 29 16:25 /sbin/scsi_id -> ../lib/udev/scsi_id
$

So at least the path is actually workable after all.

The options are still wrong in the Multipath doc though.

The scsi_id examples have been updated in the DM-Multipath document for RHEL 6. The changes have been checked in to the SVN repository and built on the review staging area. I am marking this bug as MODIFIED.

Verified in Red_Hat_Enterprise_Linux-DM_Multipath-6-en-US-1-18.

Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
