Description Justin Clift 2010-05-01 22:41:50 EDT
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"

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
Comment 3 Justin Clift 2010-05-25 00:29:52 EDT
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.
Comment 5 Steven J. Levine 2010-10-12 16:33:13 EDT
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.
