Use this procedure to create a logical unit (LUN) from unassigned disk drives or remaining capacity. See the Sun StorEdge 3000 Family RAID Firmware 4.1x User's Guide for the latest information about LUN administration.
Create and partition the logical device(s).
For more information on creating a LUN, see the Sun StorEdge 3000 Family RAID Firmware 4.1x User's Guide.
Map the LUNs to the host channels that are cabled to the nodes.
For more information on mapping LUNs to host channels, see the Sun StorEdge 3000 Family RAID Firmware 4.1x User's Guide.
You can have a maximum of 64 shared LUNs.
Ensure that each LUN has an associated entry in the /kernel/drv/sd.conf file.
For more information, see the Sun StorEdge 3000 Family Installation, Operation, and Service Manual.
To make the changes to the /kernel/drv/sd.conf file active, perform one of the following options.
If necessary, label the LUNs.
If the cluster is online and active, update the global device namespace.
If you want a volume manager to manage the new LUN, run the appropriate Solstice DiskSuite/Solaris Volume Manager commands or VERITAS Volume Manager commands. Use these commands to incorporate the new LUN into a diskset or disk group.
For information on administering LUNs, see your Sun Cluster system administration documentation.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
If you want the new LUN to be a quorum device, add the quorum device.
For the procedure about how to add a quorum device, see your Sun Cluster system administration documentation.
