IBM DS System Storage common commands examples

By root, 9 June, 2014
In these examples, we will use 
dscli
command without connecting to the storage device by using a profile. If you want to configure yours, check the following tutorial on iBM website. However, if you are connected directly to the storage device, you can use them without it, just stick with bold green from the examples below.

How to list the physical disks attached to the storage with 
lsddm
command:

The unassigned ones from our example below are newly added - after a minute they will be automatically initialised and seen differently, depending of RAID level: spare required or unconfigured.
