[iprconfig 3/8] JBOD – Using single disks

When you have multiple disks on your system, you can arrange them in such a way that you can use each as single, individual disks. Iprutils labels this approach as Just a Bunch Of Disk or, JBOD.

Formating for JBOD means that your system will see all disks as individual disks, and also that you will not be able to create raids with them. The syntax is:

iprconfig -c format-for-jbod [sdN | sgX]…

where sdN is seen from iprconfig -c show-config and sgX is seen from iprconfig -c show-alt-config

There will be no output while the formatting runs, but after the formatting finishes, you will see your disks as Physical Disks:

Please keep in mind that formatting takes long to finish. This above formatting took about 20 minutes to complete.

Now you have single disks to work with.
