# forallmsas show disks ; done

The CLI syntax for specifying disks in enclosures differs based on the controller type used

in the array. The following vdisk and volume creation steps are organized by controller

types MSA2212fc and MSA2312fc, and provide examples of command-line syntax for

specifying drives. This assumes that all arrays in the system are using the same controller

type.

• MSA2212fc Controller

Disks are identified by SCSI ID. The first enclosure has disk IDs 0-11, the second has

16-27, the third has 32-43, and the fourth has 48-59.

• MSA2312fc Controller

Disks are specified by enclosure ID and slot number. Enclosure IDs increment from 1.

Disk IDs increment from 1 in each enclosure. The first enclosure has disk IDs 1.1-12,

the second has 2.1-12, the third has 3.1-12, and the fourth has 4.1-12.

Depending on the order in which the controllers powered on, you might see different ranges

of disk numbers. If this occurs, run the rescan command again.

4. If you have MSA2212fc controllers in your arrays, use the following commands to create

vdisks and volumes for each enclosure in all of the arrays. When creating volumes, all

volumes attached to a given MSA must be assigned sequential LUN numbers to ensure

correct assignment of multipath priorities.

a. Create vdisks in the MGS and MDS array. The following example assumes the MGS

and MDS do not have attached disk enclosures and creates one vdisk for the controller

enclosure. The disks 0-4 are mirrored by disks 5-9 in this configuration:

# formdsmsas create vdisk level raid10 disks 0-4:5-9 assigned-to a spare 10,11 mode offline vdisk1;

done

Creating vdisks using offline mode is faster, but in offline mode the vdisk must be

created before you can create the volume. Use the show vdisks command to check

the status. When the status changes from OFFL, you can create the volume.

# formdsmsas show vdisks; done

Make a note of the size of the vdisks and use that number <size> to create the volume

in the next step.

b. Create volumes on the MDS and MDS vdisk.

# formdsmsas create volume vdisk vdisk1 size <size> mapping 0-1.11 volume1; done

c. Create vdisks in each OST array. For OST arrays with one attached disk drive enclosure,

create two vdisks, one for the controller enclosure and one for the attached disk

enclosure. For example:

# forostmsas create vdisk level raid6 disks 0-10 assigned-to a spare 11 mode offline vdisk1; done

# forostmsas create vdisk level raid6 disks 16-26 assigned-to b spare 27 mode offline vdisk2; done

Use the show vdisks command to check the status. When the status changes from

OFFL, you can create the volume.

# forostmsas show vdisks; done

Make a note of the size of the vdisks and use that number <size> to create the volume

in the next step.

d. Create volumes on all OST vdisks. In the following example, LUN numbers are 21 and

22.

# forostmsas create volume vdisk vdisk1 size <size> mapping 0-1.21 volume1; done

# forostmsas create volume vdisk vdisk2 size <size> mapping 0-1.22 volume2; done

5. If you have MSA2312fc controllers in your arrays, use the following commands to create

vdisks and volumes for each enclosure in all of the arrays. When creating volumes, all

volumes attached to a given MSA must be assigned sequential LUN numbers to ensure
