Installing Partner Groups

This section contains the procedure for an initial installation of storage array partner groups in a cluster.

How to Install a Partner Group

Use this procedure to install and configure storage array partner groups in a running cluster. To add storage array partner groups to an existing cluster, use the procedure in How to Add Partner Groups. Perform the steps in this procedure in conjunction with the procedures in the Sun Cluster software installation documentation and your server hardware manual.

1. Install the host adapters in the nodes to be connected to the storage arrays.

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

2. Install the Fibre Channel (FC) switches.

   For the procedure about how to install an FC switch, see the documentation that shipped with your switch hardware.

   Note - If you are using two FC switches and Sun SAN software to create a storage area network (SAN), see SAN Considerations for more information.

   ---

3. Are you installing Sun StorEdge T3+ arrays?

   • If no, proceed to Step 4

   • If yes, install the media interface adapters (MIAs) in the Sun StorEdge T3 arrays that you are installing, as shown in Figure 2-1.

     For the procedure about how to install a media interface adapter (MIA), see the Sun StorEdge T3 and T3+ Array Configuration Guide.

4. If necessary, install GBICs or SFPs in the FC switches, as shown in Figure 2-1.

   For the procedure about how to install a GBIC or an SFP to an FC switch, see the documentation that shipped with your FC switch hardware.

5. Set up a Reverse Address Resolution Protocol (RARP) server on the network on which the new storage arrays are to reside.

   This RARP server enables you to assign an IP address to the new storage arrays. Assign an IP address by using the storage array's unique MAC address. For the procedure about how to set up a RARP server, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

6. Cable the storage arrays, as shown in Figure 2-1.

   1. Connect the storage arrays to the FC switches by using fiber-optic cables.

   2. Connect the Ethernet cables from each storage array to the LAN.

   3. Connect interconnect cables between the two storage arrays of each partner group.

   4. Connect power cords to each storage array.

   For the procedure about how to install fiber-optic, Ethernet, and interconnect cables, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

7. Power on the storage arrays. Verify that all components are powered on and functional.

   For the procedure about how to power on the storage arrays and verify the hardware configuration, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

8. Administer the storage arrays' network settings.

   Use the telnet command to access the master controller unit and administer the storage arrays. For the procedure on how to administer the storage array network addresses and settings, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

   The master controller unit is the storage array that has the interconnect cables attached to the second port of each interconnect card, when viewed from the rear of the storage arrays. For example, Figure 2-1 shows the master controller unit of the partner group as the lower storage array. In this diagram, the interconnect cables are connected to the second port of each interconnect card on the master controller unit.

9. Install any required storage array controller firmware.

   For partner-group configurations, use the telnet command to access the master controller unit. Install the required controller firmware.

   See the Sun Cluster release notes documentation for information about accessing Sun's Info Docs on http://sunsolve.sun.com. The Info Docs list information about required patches and firmware that are available for download. For the procedure about how to apply host adapter firmware, see the firmware patch README file.

10. Ensure that each storage array has a unique target address.

    For the procedure about how to verify and assign a target address to a storage array, see the Sun StorEdge T3 and T3+ Array Configuration Guide.

11. Ensure that the cache and mirror settings for each storage array are set to auto.

    For more information, see the Sun StorEdge T3 and T3+ Array Administrator's Guide.

12. Ensure that the mp_support parameter for each storage array is set to mpxio.

    For more information, see the Sun StorEdge T3 and T3+ Array Administrator's Guide.

13. Ensure that both storage array controllers are online.

    For more information about how to correct the situation if both controllers are not online, see the Sun StorEdge T3 and T3+ Array Administrator's Guide.

14. (Optional) Configure the storage arrays with the desired logical volumes.

    For the procedure about how to create and initialize a logical volume, see the Sun StorEdge T3 and T3+ Array Administrator's Guide. For the procedure about how to mount a logical volume, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

15. Reset the storage arrays.

    For the procedure about how to reboot or reset a storage array, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

16. On all nodes, install the Solaris operating environment. Apply the required Solaris patches for Sun Cluster software and storage array support.

    For the procedure about how to install the Solaris operating environment, see your Sun Cluster software installation documentation.

    See the Sun Cluster release notes documentation for information about accessing Sun's Info Docs on http://sunsolve.sun.com. The Info Docs list information about required patches and firmware that are available for download. For the procedure about how to apply host adapter firmware, see the firmware patch README file.

17. Install any required patches or software for Sun StorEdge Traffic Manager software support to nodes.

    For the procedure on how to install the Sun StorEdge Traffic Manager software, see the Sun StorEdge Traffic Manager Installation and Configuration Guide at http://www.sun.com/products-n-solutions/hardware/docs/. For a list of required patches for Sun StorEdge Traffic Manager software, see the Sun StorEdge Traffic Manager Software Release Notes on http://www.sun.com/storage/san.

18. Edit the /kernel/drv/scsi_vhci.conf file to activate the Sun StorEdge Traffic Manager software functionality. Set the mpxio-disable parameter to no.

    mpxio-disable="no"

19. Perform a reconfiguration boot on all nodes to create the new Solaris device files and links.

20. On all nodes, update the /devices and /dev entries.

    # devfsadm -C

21. On all nodes, confirm that all storage arrays that you installed are visible.

    # luxadm display
