Appendix A: Using SSSU to configure the EVA

The sample SSSU script provided in this appendix creates and presents multiple Vdisks to vSphere hosts.

The script performs the following actions:

• Create a disk group with 24 disks.

• Set the disk group sparing policy to single-drive failure.

• Create Vdisk folders.

• Add two vSphere hosts and their respective HBA presentation to the EVA and assign the appropriate host profiles.

• Create five Vdisks and present each to both vSphere hosts.
