How to Add a Storage Array to a Running Cluster
Use this procedure to add new storage array to a running cluster. To install to a new Sun Cluster that is not running, use the procedure in How to Install a Storage Array.
If you need to add a storage array to more than two nodes, repeat the steps for each additional node that connects to the storage array.
Note - This procedure assumes that your nodes are not configured with dynamic reconfiguration functionality.
If your nodes are configured for dynamic reconfiguration, see the Sun Cluster system administration documentation and skip steps that instruct you to shut down the node.
How to Perform Initial Configuration Tasks on the Storage Array
Power on the storage array.
Set up and configure the storage array.
For the procedures on configuring the storage array, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.
If necessary, upgrade the storage array's 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. For the procedure on applying any host adapter's firmware patch, see the firmware patch README file.
Configure the new storage array. Map the LUNs to the host channels.
For the procedures on setting up logical drives, logical volumes, and LUNs, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual or Sun StorEdge 3000 Family RAID Firmware 3.27 User's Guide.
How to Connect the Storage Array to FC Switches
Use this procedure if you plan to add a storage array to a SAN environment. If you do not plan to add the storage array to a SAN environment, go to How to Connect the Node to the FC Switches or the Storage Array.
Install the SFPs in the storage array that you plan to add.
For the procedure on installing an SFP, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.
If necessary, install GBICs or SFPs in the FC switches.
For the procedure on installing a GBIC or an SFP to an FC switch, see the documentation that shipped with your FC switch hardware.
Install a fiber-optic cable between the new storage array and each FC switch.
For the procedure on installing a fiber-optic cable, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.
How to Connect the Node to the FC Switches or the Storage Array
Use this procedure when you add a storage array to a SAN or DAS configuration. In SAN configurations, you connect the node to the FC switches. In DAS configurations, you connect the node directly to the storage array.
Determine the resource groups and device groups that are running on all nodes.
Record this information because you will use it in Step 14 of this procedure to return resource groups and device groups to these nodes.
# scstat
Move all resource groups and device groups off the node that you plan to connect.
# scswitch -S -h nodename
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.
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.
Connect fiber-optic cables between the node and the FC switches or the storage array.
For the procedure on installing a fiber-optic cable, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.
If necessary, install the required Solaris patches for storage array support on the node.
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. For the procedure on applying any host adapter's firmware patch, see the firmware patch README file.
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"
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 LUNs on the new storage array.
# format
(Optional) On the node, verify that the device IDs (DIDs) are assigned to the new storage array.
# scdidadm -l
Repeat Step 2 to Step 12 for each remaining node that you plan to connect to the storage array.
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 the 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 or VERITAS Volume Manager documentation.
