This article describes the process for connecting a SIRIS to a an ESXi host. These instructions apply to virtual and physical SIRIS appliances.
First, set up the Hypervisor Connection.
1. Start up the ESXi virtualization via the web interface by selecting Virtualize via Hypervisor option on the Restore page.

Once you start the virtual machine from the web interface, you can see the vSphere tasks in Recent Tasks.

2. The iSCSI targets to the .datto file are created on the SIRIS, and we connect to them from the ESXi host using the specified iSCSI adapter.

3. The HBA is re-scanned so that vSphere can get information on the new devices available through the iSCSI adapter.
4. A virtual disk is created through RDM to our .datto file through the iSCSI target on the SIRIS. This is the way we attach the .datto file located on the Datto to the virtual machine we are about to create on the ESXi host. If there is more than one disk in the backup, then a virtual disk via RDM is created for each.
The RDM creation can sometimes fail. This failure will typically produce the status "A specified parameter is not correct. spec.device" under the Create virtual disk task. It will retry up to 3 times for each virtual disk that we attach to the virtual machine.
If we are unable to access the backup images on the SIRIS through iSCSI for ESXi virtualization, then we will attempt to do this via NFS as a failover.
5. The virtual machine is registered in vSphere with the <agent>-restore naming convention.
6. The virtual machine is powered on.

The screenshot verification process works the same way except for step 1, which involves manually starting up the virtual machine from the web interface. The naming convention for the virtual machine may also be slightly different.
