As shown in this example, device 4B2E is being accessed as /dev/dasdb.
As an alternative, the recommended method for bringing a disk online (automatically) is to use
the following simple command:
# chccwdev -e 4b2e
Once the disk is online, 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

Next, make a file system on the new partition:
# mke2fs -j /dev/dasdb1
