Hello,
I have successfully created my first RDM from a EMC CX4-240 LUN. I now see the mapping in ESXi 4.1 and have created the raw disk for my Red Hat Enterprise 6 vm. I am now in cli on the RHEL 6 vm and am not sure where to look for the new mount. Do I have to manually create this mount, or will it just pop up somewhere in Red Hat?
The more detailed the explanation the better!
Thank you!
Its a disk, so its going to show up as /dev/sdX, where X changes based on how many drives the system already has. In your case, because you only have 2, you new drive is probably going to be /dev/sdb.
Check that by comparing the size that parted or fdisk reports for that device to the known size.
You will need to put a filesystem on it yourself (with mkfs) and then mount it (using mount).
How do I know which device do I point mkfs to?
You'll have to take a look at your devices in Linux to see which one is new and of the correct size. Check /proc/scsi/scsi and dmesg to help figure it out.
--M
I see the following:
/proc/scsi/scsi:
dmesg:

Still not sure what to look for in dev.

Yep, that did the trick!
Thank you so much for your time and patience! I really do appreciate it!
