Chapter 22. Additional Information for IBM System z Users 5. Adding DASD The following is an example of how to add a DASD volume: Note Make sure the device is attached or linked to the Linux system if running under VM. CP LINK RHEL4X 4B2E 4B2E MR DASD 4B2E LINKED R/W Procedure 22.1. Bringing a disk online 1. Use the cd command to change to the /sys/ directory that represents that volume: # cd /sys/bus/ccw/drivers/dasd-eckd/0.0.4b2e/ # ls -l total 0 -r--r--r-- 1 root root 4096 Aug 25 17:04 availability -rw-r--r-- 1 root root 4096 Aug 25 17:04 cmb_enable -r--r--r-- 1 root root 4096 Aug 25 17:04 cutype -rw-r--r-- 1 root root 4096 Aug 25 17:04 detach_state -r--r--r-- 1 root root 4096 Aug 25 17:04 devtype -r--r--r-- 1 root root 4096 Aug 25 17:04 discipline -rw-r--r-- 1 root root 4096 Aug 25 17:04 online -rw-r--r-- 1 root root 4096 Aug 25 17:04 readonly -rw-r--r-- 1 root root 4096 Aug 25 17:04 use_diag 2. Next, check to see if it is already online: # cat online 0 3. If it is not online, run the following command to bring it online: # echo 1 > online # cat online 1 4. Verify which block devnode it is being accessed as: # ls -l 230

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 auto-creating one partition for the whole disk... writing volume label... writing VTOC... checking ! wrote NATIVE! rereading partition table... Next, make a file system on the new partition: # mke2fs -j /dev/dasdb1 mke2fs 1.35 (28-Feb-2004) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 300960 inodes, 600816 blocks 30040 blocks (5.00%) reserved for the super user 231
