SAN LUN disk space and /dev/dm-5
I got some space from a SAN LUN to a redhat box. If I do "fdisk -l", I can see the disk size under various /dev/* like /dev/hda, /dev/hdd, /dev/dm-4, /dev/dm-5. I made a Linux partition on the /dev/dm-5 which became /dev/dm-5p1 but I cannot see the file /dev/dm-5p1 anywhere in the system. What is the /dev/dm-5p1 and how can I actually see it?

The dm- devices are part of the device mapper system. They are not how I would recommend accessing the disks that you have been allocated.
I would suggest that first you look at the output of the command Quote:
I would expect there to be something showing the drive being detected and normally you would get a device such as Quote:
You can also look at Quote:

If you can post more information from dmesg and the /proc/partitions file it should be easier to identify what hardware your OS is seeing. |
