Hi,
Have a VRTX Chassis enclosure populated with two Dell PowerEdge M620 Blades
and has a built-in DAS storage. Created a 1 TB Virtual Disk from the DAS
storage using the Dell iDRAC interface. This block device is accessible
from the two blades (CentOS 7 OS) like shown below,
[root@node1 ~]# lsblk /dev/sdc
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sdc 8:32 0 1024G 0 disk
[root@node2 ~]# lsblk /dev/sdc
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sdc 8:32 0 1024G 0 disk
oVirt rpms has been installed on both the blades with the aim of
configuring them as oVirt nodes with Live Migration feature. But other than
the DAS we don't have any storage which can be used as shared storage. So
can some one please tell me whether the above block disk can be used as a
shared storage (i.e mounted on the two nodes at the same time) and if it is
possible how can this be done. Thank you.

Hello rex.
I have a very similar situation and I'm interested to find out how
people are doing to use DAS in these types of environments.
Thanks

In theory, if you can see the DAS LUN with multipath, you can build the
storage domain as if it's FC. Might need to play with multipath settings to
make sure it's not filtered out.
