Is it possible to mount a physical disk (/dev/mapper/ disk) on one of my Oracle VM server

user897654321Nov 14 2014 — edited Nov 19 2014

I have a physical disk that I can see from multipath -ll  that shows up as such

# multipath -ll

....

3600c0ff00012f4878be35c5401000000 dm-115 HP,P2000G3 FC/iSCSI

size=410G features='1 queue_if_no_path' hwhandler='0' wp=rw

|-+- policy='round-robin 0' prio=50 status=active

| `- 7:0:0:49  sdcs 70:0   active ready running

`-+- policy='round-robin 0' prio=10 status=enabled

  `- 10:0:0:49 sdcr 69:240 active ready running

...

That particular is visible in the OVMM Gui as a physical disk that I can present to one of my VMs but currently its not presented to any of them.

I have about 50 physical LUNs that my Oracle VM server can see.  I believe I can see all of them from a fdisk -l, but "dm-115" (which is from the multipath above) doesnt show up.

This disk has 3 usable partitions on it, plus a Swap.

I want to mount the 3rd partition temporarily on the OVM server itself and I receive

# mount /dev/mapper/3600c0ff00012f4878be35c5401000000p3 /mnt

mount: you must specify the filesystem type

If I present the disk to a VM and then try to mount the /dev/xvdx3 partition -it of course works.  (x3 - represents the 3rd partition on what ever letter position the disk shows up as)

Is this possible?
