I’m trying to get a SLES 11 sp1 setup with Multipath

I’ve taken to following steps to setup and enable multipath on the server in question:

1. initially install the OS on a single path (multipath installation rendered the machine incapable of booting)
2. reboot machine with multiple paths added
3. create /etc/multipath.conf (included below)  
3.5) update the packages listed in [KB article 7008995](http://www.novell.com/support/kb/doc.php?id=7008995)
4. add dm-multipath to the INITRD\_MOUDULES and run mkinitrd
5. add boot.multipath and multipathd to the boot sequence
6. check that fstab and menu.lst are using /dev/disk/by-id/scsi-### to mount disks
7. reboot

This sequence of steps results in a properly working multipath enabled OS when I’m using SLES 11 sp2 but fails to work with sp1.

If anyone out there has any thoughts on this I’d appreciate any advice.

Here’s the /etc/multipath.conf file

```auto
##
## This is a template multipath-tools configuration file
## Uncomment the lines relevent to your environment
##
 defaults {
#	udev_dir /dev
#	polling_interval 10
#	path_selector "round-robin 0"
#	path_grouping_policy	multibus
#	getuid_callout "/lib/udev/scsi_id --whitelisted --device=/dev/%n"

devices {
# Device attributed to EMC VNX

  }
}
```

I’m sorry I don’t have any multipath experience and am therefore unable  
to offer any advise with respect to your issue.

I do see a number of open bugs affecting multipath. Perhaps you would  
be better off opening a Service Request in this instance.
