3. Verify that removable media services are not running.

   # svcs volfs STATE STIME FMRI disabled 10:39:12 svc:/system/filesystem/volfs:default

4. (Optional) Identify the device.

   For example:

   # cd /dev/rdsk # ls -l c*0 | grep usb lrwxrwxrwx 1 root root 55 Mar 5 10:35 c2t0d0s0 -> ../../devices/pci@1f,0/usb@c,3/storage@3/disk@0,0:a,raw

   In this example, the diskette device is c2t0d0s0.

5. Select one of the following to mount or unmount a USB mass storage device:

   • Mount a USB mass storage device.

     # mount [ -F fstype ] block-device mount-point

     This example shows how to mount a device with a UFS file system:

     # mount /dev/dsk/c1t0d0s2 /mnt

     This example shows how to mount a device with a PCFS file system on a SPARC system:

     # mount -F pcfs /dev/dsk/c3t0d0s2:c /mnt

     This example shows how to mount a device with a PCFS file system on an x86 system:

     # mount -F pcfs /dev/dsk/c3t0d0p0:c /mnt

     This example shows how to mount a CD with a read-only HSFS file system:

     # mount -F hsfs -o ro /dev/dsk/c1t0d0s2 /mnt

   • Unmount a USB mass storage device.

     First, be sure no one is using the file system on the device.

     For example:

     # fuser -c -u /mnt # umount /mnt

6. Eject the device, which is optional for CD or diskette devices.

   # eject /dev/[r]dsk/cntndnsn

   For example:

   # eject /dev/rdsk/c1t0d0s2
