How to Connect the Storage Array to FC Switches
Install the GBICs or SFPs in the storage array that you plan to add.
For the procedure about how to install a GBICs or SFPs, see the Sun StorEdge 6120 Array Installation Guide.
If necessary, install GBICs or SFPs in the FC switches.
For the procedure about how to install a GBIC or an SFP, see the documentation that shipped with your FC switch hardware.
Install the Ethernet cable between the storage array and the Local Area Network (LAN).
If necessary, daisy-chain or interconnect the storage arrays.
For the procedure about how to install interconnect cables, see the Sun StorEdge 6120 Array Installation Guide.
Install a fiber-optic cable between the FC switch and the storage array.
For the procedure about how to install a fiber-optic cable, see the Sun StorEdge 6120 Array Installation Guide.
How to Connect the Node to the FC Switches or the Storage Array
Determine the resource groups and device groups that are running on all nodes.
Record this information because you use this information in Step 18 of this procedure to return resource groups and device groups to these nodes.
# scstat
Move all resource groups and device groups off Node N.
# scswitch -S -h from-node
Do you need to install a host adapter in Node N?
Is the host adapter that you are installing the first FC host adapter on Node N?
If no, skip to Step 6.
If yes, determine whether the required drivers for the host adapter are already installed on this node. For the required packages, see the documentation that shipped with your host adapters.
Are the Fibre Channel support packages installed?
If yes, proceed to Step 6.
If no, install the packages.
The storage array packages are located in the Product directory of the Solaris CD-ROM. Add any necessary packages.
Shut down and power off Node N.
For the procedure about how to shut down and power off a node, see your Sun Cluster system administration documentation.
Install the host adapter in Node N.
For the procedure about how to install a host adapter, see the documentation that shipped with your host adapter and node.
Power on and boot Node N into noncluster mode.
For the procedure about how to boot a node in noncluster mode, see your Sun Cluster system administration documentation.
If necessary, upgrade the host adapter firmware on Node N.
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.
If necessary, install a GBIC or an SFP in the FC switch or the storage array.
For the procedure about how to install a GBIC or an SFP, see the documentation that shipped with your FC switch hardware. For the procedure on how to install a GBIC or an SFP, see the Sun StorEdge 6120 Array Installation Guide.
Connect a fiber-optic cable between the FC switch and Node N.
For the procedure about how to install a fiber-optic cable, see the Sun StorEdge 6120 Array Installation Guide.
If necessary, install the required Solaris patches for storage array support on Node N.
For a list of required Solaris patches for storage array support, see the Sun StorEdge 6120 Array Release Notes.
On the node, update the /devices and /dev entries.
# devfsadm -C
On the node, update the paths to the DID instances.
# scgdevs
If necessary, label the new logical volume.
For the procedure about how to label a logical volume, see the Sun StorEdge 6020 and 6120 Array System Manual.
(Optional) On Node N, verify that the device IDs (DIDs) are assigned to the new storage array.
# scdidadm -l
Repeat Step 2 through Step 16 for each remaining node that you plan to connect to the storage array.
(Optional) Return the resource groups and device groups that you identified in Step 1 to the original nodes.
# scswitch -z -g resource-group -h nodename # scswitch -z -D device-group-name -h nodename
For more information, see your Sun Cluster system administration documentation.
Perform volume management administration to incorporate the new logical volumes into the cluster.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
