I have a Promise M300i iSCSI with 2 LUNs. A 2TB LUN with ID
2260-0001-557c-af0a and a 4TB LUN with ID 22d9-0001-553e-4d6a.
What's strange, is the very first time I ran discovery I saw both
LUNs. I checked the 2TB LUN and storage failed to add, I don't have
logs at this time, but I went back to repeat the process and now only
1 LUN shows in the GUI (see attached image). Also the size it reports
is way off.
Looking at VDSM logs, I get this output when doing the login to a target

}
In that output both LUNs are seen. I couldn't tell from the code what
format the "capacity" is in, but now the interface shows only the LUN
with the "4d6a" GUID as being 18TB.
I've attached the VDSM Logs from the point of selecting my datacenter
to after clicking "Login". Any suggestions?

the LUN you don't see is 'dirty' and vdsm filters it.
there are some patches for showing all LUNs and just graying them out at
ui level (but these are post ovirt 3.1.
dd with zeros the start of your LUN should bring it back

I re-initialized the RAID array, and attempted adding the storage
domain that resulted in failure again. This is the error in Web
interface
"Error: Cannot attach Storage. Storage Domain doesn't exist."
I've attached log vdsm that is a snapshot from the time right before
clicking "Ok" and the error. ovirt-engine is 3.1 and vdsm is
4.10.0-4. Both engine and node are CentOS 6.2
I attempted to run the failing command manually
# /sbin/lvm pvcreate --config " devices { preferred_names =
[\"^/dev/mapper/\"] ignore_suspended_devices=1 write_cache_state=0

Can't open /dev/mapper/222600001557caf0a exclusively. Mounted filesystem?
What's strange is fuser shows nothing using that path, or the
/dev/dm-4 path it's referencing. However the device created in dmesg
(/dev/sde) does show usage
