Installing RAID Storage Arrays

This section contains instructions on installing storage arrays both in new clusters and in existing clusters.

How to Install a RAID Storage Array in a New Cluster

Use this procedure to install and configure RAID storage arrays before installing the Solaris operating environment and Sun Cluster software on your nodes. To add storage arrays to an operating cluster, use the procedure, How to Add a RAID Storage Array to an Existing Cluster.

The storage array must be mirrored with another storage array to ensure high availability.

Before You Begin

This procedure assumes that the hardware is not connected.

To attach a JBOD storage array to a RAID storage array as an expansion unit, attach the JBOD storage array before connecting the RAID storage array to the nodes. For more information, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.

1. Install the host adapters in the nodes that connect to the RAID storage array.

   For the procedure about how to install host adapters, see the documentation that shipped with your host adapters and nodes.

2. Cable the RAID storage array to the nodes.

   Ensure the cable does not exceed bus length limitations. For more information on bus length limitations, see the documentation that shipped with your hardware.

   For the procedure about how to cable the storage arrays, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.

3. RAID storage arrays have redundant power inputs. Connect each power cord from the RAID storage array to a different power source.

   Different RAID storage arrays can share power sources.

4. Install the Solaris operating environment, then apply any required Solaris patches.

   For software installation procedures, see your Sun Cluster software installation documentation.

   Note –

   For the current list of patches that are required for the Solaris operating environment, refer to SunSolve. SunSolve is available online to Sun service providers and to customers with SunSolve service contracts at the SunSolve site: http://sunsolve.sun.com.

   ---

5. If necessary, install the qus driver and appropriate driver patches.

   For driver installation procedures, see the Sun StorEdge PCI Dual Ultra 3 SCSI Host Adapter Release Notes.

6. If necessary, upgrade the controller firmware.

7. Set up and configure the RAID storage arrays with logical units (LUNs).

   For the procedure about how to set up the storage array with LUNs, see How to Create and Map a LUN.

   ---

   Note –

   If you want to use the Configuration Service Console, perform this step after Step 8.

   ---

8. (Optional) Install the Configuration Service.

   For the procedure about how to install the Configuration Service, see the Sun StorEdge 3000 Family Configuration Service 1.5 User’s Guide for the Sun StorEdge 3310 SCSI Array and the Sun StorEdge 3510 FC Array.

9. Install the Sun Cluster software and volume management software.

   For software installation procedures, see the your Sun Cluster software installation documentation.

How to Add a RAID Storage Array to an Existing Cluster

Use this procedure to add RAID storage arrays to a running cluster. If you need to install a storage array in a new cluster, use the procedure in How to Install a RAID Storage Array in a New Cluster.

Before You Begin

This procedure assumes that your nodes are not configured with dynamic reconfiguration functionality.

If your nodes are configured for dynamic reconfiguration, see your Sun Cluster Hardware Administration Manual for Solaris OS.

This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix A, Sun Cluster Object-Oriented Commands, in Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS.

To perform this procedure, become superuser or assume a role that provides solaris.cluster.read RBAC (role-based access control) authorization.

1. Install any RAID storage array packages and patches on nodes.

   Note –

   For the most current list of software, firmware, and patches that are required for the RAID storage array, refer to SunSolve. SunSolve is available online to Sun service providers and to customers with SunSolve service contracts at the SunSolve site: http://sunsolve.sun.com.

2. Power on the RAID storage array.

   For procedures about how to power on the storage array, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.

3. Configure the RAID storage array.

   For the procedure about how to create LUNs, see How to Create and Map a LUN.

4. On each node that is connected to the RAID storage array, ensure that each LUN has an associated entry in the /kernel/drv/sd.conf file.

   For more information, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.

5. Shut down the first node.

   For the procedure about how to shut down and power off a node, see your Sun Cluster system administration documentation.

6. If you are installing new host adapters, power off the first node.

   For the procedure about how to power off a node, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.

7. Install the host adapters in the first node.

   For the procedure about how to install host adapters, see the documentation that shipped with your host adapters and nodes.

8. Cable the RAID storage array to the first node.

   Ensure the cable does not exceed bus length limitations. For more information on bus length limitations, see the documentation that shipped with your hardware.

   For the procedure about how to cable the storage arrays, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.

9. Boot the first node.

   For the procedure about how to boot cluster nodes, see Chapter 3, Shutting Down and Booting a Cluster, in Sun Cluster System Administration Guide for Solaris OS.

10. Verify that the first node recognizes the new host adapters and disk drives.

    If the node does not recognize the new hardware, check all hardware connections and repeat installation steps you performed in Step 7.
