Red Hat Bugzilla – Bug 587997
The default options for scsi_id have changed, which needs updating in the doc and man page
Last modified: 2010-11-11 10:27:41 EST
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.
