Mounting in Linux

[jcbassett]

I have a need to mount to the Starwinds ISCSI drive from a Linux host. I was able to discover the targets. As such sdc appeared to be the newly found drive. However, dm-0 and dm-1 also appeared. I am able to fdisk /dev/sdc and write out a partition table. I that made the drive ext2. However, I cannot mount the drive. I am getting this error:
[root@GSIOVM /]# mount -t ext3 /dev/dm-0 /mnt/iscsinas
mount: /dev/dm-0 already mounted or /mnt/iscsinas busy
[root@GSIOVM /]# mount -t ext3 /dev/sdc1 /mnt/iscsinas
mount: /dev/sdc1 already mounted or /mnt/iscsinas busy

At first, I was able to mount the dm-0 device. But after a reboot, it too gives me the issue.

One correction: I made the drive ext3
