RHEL 5 parted command step by step.

To test this we used RHEL 5 n vmware.
1. Add a new SCSI type hard disk
2. vm machine will save it and process for you
3. after may be one minute run fdisk -l as root and see if you can see the disk you created

Disk /dev/sdb: 1073 MB, 1073741824 bytes
81 heads, 26 sectors/track, 995 cylinders
Units = cylinders of 2106 * 512 = 1078272 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1         186      195312+  83  Linux
Partition 1 has different physical/logical endings:
     phys=(24, 80, 26) logical=(185, 39, 2)

Now run the command:

[root@smtreeprd04 ~]# parted /dev/sdb

GNU Parted 1.8.1

Using /dev/sdb

Welcome to GNU Parted! Type 'help' to view a list of commands.

Got following error:

(parted) mkpart

Lets label the disk:

(parted) mklabel msdos

Now exit the parted utility and format the partition with mkfs
