Storage Array Cabling Configurations

You can install the StorEdge 3510 and 3511 FC RAID arrays 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 provide examples of configurations with multipathing solutions. With direct attach storage (DAS) configurations with multipathing, you map each LUN to each host channel. All nodes can see all 256 LUNs.

Figure 1–1 Sun StorEdge 3510 Direct Attach Storage (DAS) Configuration With Multipathing and Two Controllers

Figure 1–2 Sun StorEdge 3511 Direct Attach Storage (DAS) Configuration With Multipathing and Two Controllers

The two-controller SAN configurations allow 32 LUNs to be mapped to each pair of host channels. Since these configurations use multipathing, each node sees a total of 64 LUNs.

   • SPARC: For the Sun StorEdge 3510 storage array, at least Sun StorEdge SAN Foundation software version 4.2.

   • SPARC: For the Sun StorEdge 3511 storage array, at least Sun StorEdge SAN Foundation software version 4.4.

   • x86:For x86 based clusters, at least the Sun StorEdge SAN Foundation software that is bundled with Solaris 10.

   For the procedure about how to install the Sun StorEdge Traffic Manager software, see How to Install Sun Multipathing Software in Sun Cluster Software Installation Guide for Solaris OS.

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

    # devfsadm -C

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

    # luxadm probe

12. If necessary, label the LUNs.

    # format

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

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

Steps

1. Determine the resource groups and device groups that are running on all nodes.

   Record this information because you will use it in Step 12 of this procedure to return resource groups and device groups to these nodes.

   # scstat

2. Move all resource groups and device groups off the node that you plan to connect.

   # scswitch -S -h from-node

3. Determine if you need to install host adapters in the node.

   • If no, skip to Step 4.

   • If yes, see the documentation that shipped with your host adapters.

4. If necessary, install GBICs or SFPs to the FC switches or the storage array.

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

   For the procedure on installing a GBIC or an SFP to a storage array, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.

5. Connect fiber-optic cables between the node and the FC switches or the storage array.
