storcli with multiple disks from different enclosures

Creating a Virtual device with the AVAGO storcli command-line tool under Linux. Two examples are included:

  1. All disks are from one of the enclosure. All disks are included explicitly.
  2. Disks from two enclosures are included. One controller with two enclosures.

Check out how to Install the new storcli to manage (LSI/AVAGO/Broadcom) MegaRAID controller under CentOS 7
There are 31 disks of 36 harddisk bays. 5 are missing on purpose for the examples.

The initial states of the controller and the disks.

Here is the output of the storcli:

Example 1) All disks are from one of the enclosure.

All disks are included explicitly because not all disks are present in the sequence from the first slot to the last one.

storcli /c0 add vd type=r6 drives=37:0,1,2,3,4,6,7,8,10,11,13,14,16,17 pdcache=on WB ra Strip=1024

All included disks are from one enclosure and only the slot IDs are enumerated separating them with commas.

The status of a successful command is “Success” and the description is “Add VD Succeeded”. The virtual drive is created successfully.

Because if you use a valid range 37:0-17 (enclosure:disk_range(N-M)) with missing disks it throws an error “Invalid PDs specified”. All disks in range must be present and in “UGood” (i.e. “Unconfigured Good” state). No virtual drive is created!

Example 2) Disks from two enclosures are included.
