Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

Hardware compatibility list (HCL)

The hardware compatibility list contains information about supported hardware

and is updated regularly. Before installing or upgrading Storage Foundation and

High Availability Solutions products, review the current compatibility list to

confirm the compatibility of your hardware and software.

For the latest information on supported hardware, visit the following URL:

For information on specific HA setup requirements, see the Veritas Cluster Server

Installation Guide.

I/O fencing requirements

Depending on whether you plan to configure disk-based fencing or server-based

fencing, make sure that you meet the requirements for coordination points:

■ Coordinator disks

See “Coordinator disk requirements for I/O fencing” on page 44.

■ CP servers

See “CP server requirements” on page 45.

If you have installed Storage Foundation Cluster File System in a virtual

environment that is not SCSI-3 PR compliant, review the requirements to configure

non-SCSI3 server-based fencing.

See “Non-SCSI3 I/O fencing requirements” on page 48.

Coordinator disk requirements for I/O fencing

Make sure that the I/O fencing coordinator disks meet the following requirements:

■ For disk-based I/O fencing, you must have three coordinator disks.

■ The coordinator disks can be DMP devices or iSCSI devices.

■ Each of the coordinator disks must use a physically separate disk or LUN.

Symantec recommends using the smallest possible LUNs for coordinator disks.

■ Each of the coordinator disks should exist on a different disk array, if possible.

■ The coordinator disks must support SCSI-3 persistent reservations.

■ Symantec recommends using hardware-based mirroring for coordinator disks.

■ Coordinator disks must not be used to store data or must not be included in

disk groups that store user data.
