Unnecessary spaces in "multipath -l" command output

This document (7014442) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11 SP3

Situation

When using SLES 11 SP3 with multipath enabled, an output of the command
"multipath -l | cat -ve" does for example show the following output:

14945540000000000f86756dce9286158be4c6e3567e75ba5 dm-3 IET     ,VIRTUAL-DISK    $ 
size=8.0M features='0' hwhandler='0' wp=rw$ 
|-+- policy='service-time 0' prio=0 status=active$ 
| `- 3:0:0:64 sdi 8:128 active undef running$ 
`-+- policy='service-time 0' prio=0 status=enabled$ 
 `- 4:0:0:64 sdq 65:0  active undef running$

Extra spaces after IET and VIRTUAL-DISK can be seen in the above output.

The same output in SLES 11 SP2 does not show these spaces:

14945540000000000f86756dce9286158be4c6e3567e75ba5 dm-10 IET,VIRTUAL-DISK$

size=8.0M features='1 queue_if_no_path' hwhandler='0' wp=rw$

|-+- policy='round-robin 0' prio=0 status=active$

| `- 7:0:0:64 sdu 65:64 active undef running$

`-+- policy='round-robin 0' prio=0 status=enabled$ 
  `- 6:0:0:64 sdt 65:48 active undef running$

Resolution

This is a bug, and fix has been released March 2014.

Additional Information

Using "multipath -ll" also shows the same issue.
