Bug Description
System configuration is an IBM HS21 blade connected to an IBM DS3400 SAN.
The system is running Ubuntu 10.10 with multipath-tools version: 0.4.8-14ubuntu4
The Ubuntu OS is installed on an internal disk and not the SAN.
multipathd> show paths
hcil dev dev_t pri dm_st chk_st next_check
0:0:0:0 sda 8:0 0 [undef][ghost] [orphan]
1:0:0:0 sdb 8:16 3 [undef][ready] [orphan]
2:1:1:0 sdc 8:32 1 [undef][ready] [orphan]
It appears everything is working but multipathd cant define the maps, a multipath -v 6 shows
"360080e50001b5
That is the uuid of the path associated with /sda and /sdb but it cant seem to create it.

sda: orphaned
sdb: orphaned
The SAN is on devices sda and sdb. The internal root disk is sdc. The device sda is reporting I/O errors in syslog because multipath cannot bring up the path.

@Joe
Please attach the latest multipath.conf and lvm.conf responsible for this
stream of messages. If you could move over that logs and other stuff
from salesforce into this bug that would be ideal. Thanks.
