Confirming SAS Connections
The returned information relating to the physical disk is as follows. Some of the other preceding text is removed for
brevity. The SAS addresses are listed at the end. In this example, only one of the drive’s SAS ports is discovered, so the
second SAS address is listed as 0x0.

Using MSM to Verify Dual-Ported SAS Addresses to Disk Drives
When the Syncro CS system is running, you can use MSM to verify the dual SAS paths to disk drives in the HA-DAS
configuration by following these steps:
1.
Start MSM and access the Physical tab for the controller.
2.
Click on a drive in the left panel to view the Properties tab for the drive.
3.
Look at the SAS Address fields.
As shown in the following figure, a correctly configured and running HA-DAS cluster with both nodes active
displays dual SAS addresses on the drives and dual 4-lane SAS connections on the controller.
