2.3 Install and Update the HA RAID Controllers
1. To install the RAID controller HA key, shut down the server, remove the power cords,
open the lid, and install the HA key onto the RAID controller.
Figure 4. Install the RAID Controller HA Key
2. Repeat this process for both servers.
3. After each HA key has been installed on each of the RAID controllers in each of the
servers, close the lid on the servers. Remove the USB flash drive containing the drivers.
4. Install the SAS disk drives into the JBOD storage unit and then power on the JBOD
storage unit.
Note: SATA disk drives are not supported with this solution. Supported SAS disk drives
are dual-ported and are required for the HA RAID solution.
5. Connect the SAS cables between the servers and the external JBOD storage unit, as
exactly shown in the Figure 1.
Verify that a private LAN exists between the two servers. This private LAN connection
will be used for the cluster “heart beat” and related cluster server communications.
The public LAN must have a Windows Domain Controller and DNS server. The HA RAID
cluster nodes should be neither a domain controller nor a DNS server.
6. After connecting the SAS cables, reconnect the power cords into the servers and power
on the servers.
