Need install CVSDM to run JBODfmt formatting disks to 512Byte/Sector

Here's what I followed to format the DS2405 drives:

1. Insert the drive in the DS2405 chassis

2. "discover" the drive
# ioscan -fnC disk

3. Create device files
# insf -e

4. Discover the DS2405 if not already "visible"
# armdiscover

5. To display DS2405 information
# JBODdsp -I

6. Format the drive - command line
# JBODfmt -f /dev/dsk/c8t4d0
-or- if already formatted
# JBODfmt -foverride /dev/dsk/c8t4d0

7. Format the drive using cvui
select drive number
select "Disk"
select "Format"
