Installing and Maintaining a Sun StorEdge 3510 FC Array
This chapter describes the procedures for installing, configuring, and maintaining Sun StorEdge™ 3510 FC arrays in a Sun™ Cluster environment.
Before you perform any of the tasks in this chapter, read the entire procedure. If you are not reading an online version of this document, have the books listed in the Preface available.
This chapter contains the following procedures.
For conceptual information on multihost disks, see the Sun Cluster concepts documentation document.
Installing Storage Arrays
This section contains the procedure for an initial installation of a storage array in a new cluster configuration. To add a storage array to an operating cluster, use the procedure, How to Add a Storage Array to a Running Cluster.
You can install the StorEdge 3510 FC array in several different configurations. Use the Sun StorEdge 3000 Family Best Practices Manual to help evaluate your needs and determine which configuration is best for your situation. See your Sun service provider for currently supported Sun Cluster configurations.
The following figures illustrate two maximum configurations by using multipathing solutions.
Figure 1-1 Direct attach storage (DAS) configuration with multipathing and two controllers
With the direct attach storage (DAS) configuration with multipathing, you can configure LUNs in a variety of ways. The two maximum configuration options are as listed.
Each LUN is mapped to each host channel. This configuration allows all four nodes to see the same 256 LUNs.
Half of the LUNs are mapped to half of the nodes. This configuration allows the nodes that are connected to host channels 0 and 1 to see the same 512 LUNs. The nodes that are connected to host channels 4 and 5 can see the other 512 LUNs.
Figure 1-2 SAN configuration with multipathing and two controllers
The two-controller SAN configuration allows 32 LUNs to be mapped to each pair of host channels. Since this configuration uses multipathing, each node sees a total of 64 LUNs.
How to Install a Storage Array
Before installing or configuring your cluster, see "Known Problems" in the Sun Cluster 3.x Release Notes Supplement for important information about the StorEdge 3510 FC storage array.
Use this procedure to install and configure storage arrays before installing the Solaris operating environment and Sun Cluster software on your cluster nodes.
This procedure assumes that the hardware is not connected.
Note - If you plan to attach a StorEdge 3510 FC expansion storage array to a StorEdge 3510 FC RAID storage array, attach the expansion storage array before connecting the RAID storage array to the cluster nodes. See the Sun StorEdge 3000 Family Installation, Operation, and Service Manual for more information.
Install host adapters in the nodes that connect to the storage array.
For the procedure on installing host adapters, see the documentation that shipped with your host adapters and nodes.
If necessary, install the Fibre Channel (FC) switches.
For the procedure on installing an FC switch, see the documentation that shipped with your switch hardware.
Note - You must use FC switches when installing storage arrays in a SAN configuration.
If necessary, install gigabit interface converters (GBICs) or Small Form Factor Pluggables (SFPs) in the FC switches.
For the procedures on installing a GBIC or an SFP to an FC switch, see the documentation that shipped with your FC switch hardware.
Cable the storage array.
For the procedures on connecting your FC storage array, see Sun StorEdge 3000 Family Installation, Operation, and Service Manual.
If you plan to create a storage area network (SAN), connect the storage array to the FC switches using fiber-optic cables.
If you plan to have a direct connect configuration (DAS), connect the storage array to the nodes.
Power on the storage arrays.
Verify that all components are powered on and functional.
For the procedure on powering up the storage arrays and checking LEDs, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.
Set up and configure the storage array.
For procedures on setting up logical drives, logical volumes, and LUNs, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual or the Sun StorEdge 3000 Family RAID Firmware 3.27 User's Guide.
For the procedure on configuring the storage array, see Sun StorEdge 3000 Family Installation, Operation, and Service Manual.
Install the Solaris operating environment and any required Solaris patches.
For software installation procedures, see the 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.
Install any required storage array controller firmware.
Sun Cluster software requires patch version 113723-03 or later for each array in the cluster.
See the Sun Cluster release notes documentation for information about accessing Sun's EarlyNotifier web pages. The EarlyNotifier web pages list information about any required patches or firmware levels that are available for download.
Install any required patches or software for the Sun StorEdge SAN Foundation software and Sun StorEdge Traffic Manager software support on all nodes.
Sun Cluster software requires at least version 4.2 of the Sun StorEdge SAN Foundation software. You can obtain the Sun StorEdge SAN Foundation Software Installation Guide from http://www.sun.com/storage/san.
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.
If necessary, edit the /kernel/drv/scsi_vhci.conf file to activate multipathing functionality. Set the mpxio-disable parameter to no.
The storage array requires at least version 6.2 of the Sun StorEdge Traffic Manager.
mpxio-disable="no"
Perform a reconfiguration boot on all nodes to create the new Solaris device files and links.
On all nodes, update the /devices and /dev entries.
# devfsadm -C
On all nodes, confirm that the storage arrays that you installed are visible.
# luxadm probe
If necessary, label the LUNs.
# format
Install the Sun Cluster software and volume management software.
For software installation procedures, see the Sun Cluster software installation documentation.
