Determine Partition prior to Mount

This is how you determine what sort of partition type is located on your media attached to a Unix machine.  In this example, I am trying to mount a USB Hard Disk Drive (HDD) that has a UFS file system to my laptop.  I am working in a Solaris environment, so specific commands may vary:

1. Make sure that the USB HDD is not plugged into a USB port on the laptop.
2. Log into your system.
3. Disable the volume manager: svcadm disable volfs
4. Plug in the USB HDD to the laptop.
5. Determine the SCSI ID for the USB HDD by performing the following command:
   # rmformat -l

   1. Logical Node: /dev/rdsk/c0t2d0p0
      Physical Node: /pci@0,0/pci1028,293@1f,2/cdrom@2,0
      Connected Device: PLDS DVD-ROM DH-16D5S VD15
      Device Type: DVD Reader
   2. Logical Node: /dev/rdsk/c4t0d0p0
      Physical Node: /pci@0,0/pci1028,293@1a,7/storage@1/disk@0,0
      Connected Device: WD       10EAVS External  1.75
      Device Type: Removable
   3. Logical Node: /dev/rdsk/c0t3d0p0
      Physical Node: /pci@0,0/pci1028,293@1f,2/cdrom@3,0
      Connected Device: TSSTcorp DVD+-RW SH-216AB D200
      Device Type: DVD Reader/Writer
6. Determine the partition of the USB HDD with the following command:
   # For file in /dev/dsk/c4t0d0* ; do echo $file ; fstyp $file 2>&1 /dev/null ; done
7. Mount the USB HDD by performing the following:
   # mount /dev/dsk/c4t0d0s2 /USB
8. Enable the volume manager: svcadm enable volfs
