Managing Devices in Oracle^® Solaris 11.3

How to Create a File System on a USB Mass Storage Device

Devices typically already have default slices. If the default slices are not acceptable refer to the following sections to create the slices:

• How to Modify Partitions and Create a PCFS File System on a USB Mass Storage Device

• How to Create a Solaris Partition and Modify the Slices on a USB Mass Storage Device

1. Become an administrator.

   For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.3.

2. Add the USB device to your system. For information about hot-plugging USB devices, see:

   • Hot-Plugging USB Mass Storage Devices

   • Hot-Plugging USB Devices With the cfgadm Command

3. (Optional) Identify the USB device by using the rmformat command.

   In the following example, the device is c2t0d0p0.

   # rmformat
   Looking for devices...
   1. Logical Node: /dev/rdsk/c2t0d0p0
   Physical Node: /pci@0,0/pci108e,534a@2,1/hub@7/floppy@1/disk@0,0
   Connected Device: MITSUMI  USB FDD          1039
   Device Type: Floppy drive
   Bus: USB
   Size: 1.4 MB
   Label: <None>
   Access permissions: Medium is not write protected.

4. Perform this step only if you need to format a USB memory stick. Otherwise, skip to the next step.
   1. Insert the USB memory stick into the drive.
   2. Format the USB memory stick, if necessary.

      # rmformat -F long raw-device-file

      where raw-device-file is the storage partition in which to write the file system.

      ---

      Caution  -  Use the rmformat -F command only on USB memory sticks.

      ---

5. Determine the file system type to create, if necessary.
6. Unmount the device, if necessary.

   For more information about unmounting a USB device, see How to Mount or Unmount a USB Mass Storage Device.

7. Create the file system.

   Select one of the following:

   • Create a ZFS pool and file system on a USB stick if you need to transfer data to another system.

     # zpool create device temp-pool
     # zfs create temp-pool/data

     The following example creates a ZFS pool for the device c5t0d0 and then creates the file system on the pool.

     # zpool create c5t0d0 usbpool
     # zfs create usbpool/data

   • Create a PCFS file system.

     For information and examples, see Creating File Systems on USB Storage Devices

   • Create a legacy UFS file system.
