Troubleshooting

®
This chapter contains useful information for troubleshooting a Intel RAID High Availability Storage
system.
Reference Checklist of Required Intel® RAID High Availability
Storage Components
®
The following summary list shows the components required for a Intel RAID High Availability Storage
configuration. For more detailed information, see Chapter 2: Hardware and Software Setup.
® ®
1. Intel RAID High Availability Storage controllers: Intel RAID High Availability Storage controller
®
that supports internal SFF-8087 mini-SAS ports (used in cluster-in-a-box configurations) or Intel RAID
High Availability Storage controller with external SFF-8088 mini-SAS ports (used with discrete
computers).
2. An RWC2 version that includes Intel® RAID High Availability Storage feature support.
3. A CmdTool2 version that includes Intel® RAID High Availability Storage feature support.
4. SAS drives that fully support SCSI-3 persistent reservations (no SATA drives).
5. SAS expanders with HA-specific dual 4-lane SAS connections for the initiators and dual-port
connections to the drives.
6. Operating systems that support clustering with all of the necessary services, option selections, and
patches. (Windows Server 2008 R2 or Windows Server 2012)
7. Two local area networks: one private, one public.
Verifying Intel® RAID High Availability Storage Support in Tools
and the OS Driver
Not all versions of RWC2 support Intel® RAID High Availability Storage. The RWC2 versions that
include support for Intel® RAID High Availability Storage have specific references to clustering. It is not
always possible to determine the level of support from the RWC2 version number. Instead, look for the
RWC2 user interface features that indicate clustering support. If the second item in the RWC2 Properties
box on the dashboard for the Intel® RAID High Availability Storage controller is High Availability
Cluster status, the version supports Intel® RAID High Availability Storage. This entry does not appear
on versions of RWC2 without Intel® RAID High Availability Storage support.
You can also check the RWC2 Create Virtual Drive wizard. A Share Virtual Drive check box appears
only if the RWC2 version supports clustering, as shown in the following figure.
