How to Add a Storage System
Use this procedure to add a new storage system to a running cluster. To install systems to a new Sun Cluster configuration that is not running, use the procedure in How to Install Storage Systems.
This procedure defines Node N as the node to be connected to the storage system you are adding and the node with which you begin working.
How to Perform Initial Configuration Tasks on the Storage Array
(6320SL storage system ONLY) Install the Fibre Channel (FC) switch for the storage system if you do not have a switch installed.
Note - In a 6320SL storage system, the customer provides the switch.
For the procedure about how to install an FC switch, see the documentation that shipped with your FC switch hardware.
Configure the service processor.
For more information, see the Sun StorEdge 6320 System Installation Guide.
Create a volume.
For the procedure about how to create a volume, see the Sun StorEdge 6320 System Reference and Service Manual.
(Optional) Specify initiator groups for the volume.
For the procedure about how to specify initiator groups, see the Sun StorEdge 6320 System Reference and Service Manual.
Unpack, place, and level the storage system.
For instructions, see the Sun StorEdge 6320 System Installation Guide.
Install the system power cord and the system grounding strap.
For instructions, see the Sun StorEdge 6320 System Installation Guide.
(6320SL storage system ONLY) Connect the storage arrays to the FC switches by using fiber-optic cables.
Caution - Do not connect the switch's Ethernet port to the storage system's
private LAN.For the procedure about how to cable the storage system, see the Sun StorEdge 6320 System Installation Guide.
Power on the new storage system.
Note - The storage arrays in your system might require several minutes to boot.
For the procedure about how to power on the storage system, see the Sun StorEdge 6320 System Installation Guide.
If necessary, reconfigure the storage system's FC switches to ensure that all nodes can access each storage array.
The following configurations might prevent some nodes from accessing each storage array in the cluster.
Zone configuration
Multiple clusters that use the same switch
Unconfigured ports or misconfigured ports
How to Connect the Node to the FC Switches
Determine the resource groups and device groups that are running on all nodes.
Record this information because you use this information in Step 22 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 one or more host adapters in Node N?
Is the host adapter that you that are installing the first 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 required support packages already installed?
If yes, skip to Step 6.
If no, install the packages.
The support packages are located in the Product directory of the Solaris CD-ROM.
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 one or more host adapters in Node N.
For the procedure about how to install host adapters, see the documentation that shipped with your host adapters and nodes.
Power on and boot Node N into noncluster mode.
For more information about how to boot nodes, 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 or the Sun StorEdge 6320 System 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 6320 System Installation Guide.
Install the required Solaris patches for storage array support 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.
Install all required patches or software for Sun StorEdge Traffic Manager software support to Node N.
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 the Sun StorEdge Traffic Manager software functionality. Set the mpxio-disable parameter to no.
mpxio-disable="no"
Perform a reconfiguration boot on Node N to create the new Solaris device files and links.
Are any devices that are associated with the volume you created at an unconfigured state?
# cfgadm -al | grep disk
If no, proceed to Step 17.
If yes, configure the STMS paths.
cfgadm -c configure controllerinstance
For the procedure about how to configure STMS paths, see the Sun StorEdge Traffic Manager Installation and Configuration Guide.
Note - You need to reboot if the cfgadm command does not configure the unconfigured devices that are associated with the volume you are creating. See the Sun StorEdge Traffic Manager Installation and Configuration Guide for more information.
Update the Solaris device files and links.
# devfsadm
Note - You can wait for the devfsadm daemon to automatically update the Solaris device files and links, or you can run the devfsadm command to immediately update the Solaris device files and links.
On Node N, update the paths to the DID instances.
# scgdevs
If necessary, label the new storage array logical volume.
For the procedure about how to label a logical volume, see the Sun StorEdge 6320 System Reference and Service 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 20 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 volumes into the cluster.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
