As shown in this example, device 4B2E is being accessed as /dev/dasdb.
Use the cd command to change back to the /root directory and format the device:
# cd
# dasdfmt -b 4096 -d cdl -f /dev/dasdb -l LX4B2E -p -y
cyl 97 of 3338 |#----------------------------------------------| 2%
When the progress bar reaches the end and the format is complete, use fdasd to partition the
device:
# fdasd -a /dev/dasdb
