Note –
Sun storage documentation uses the following terms:
■
Logical volume
■
Logical device
■
Logical unit number (LUN)
This manual uses
logical volume
to refer to all such logical constructs.
This procedure relies on the following prerequisites and assumptions.
■
All nodes are booted in cluster mode and attached to the storage device.
■
The storage device is installed and configured. If you are using multipathing, the storage devices
is configured as described in the installation procedure.
■
If you are using Sun StorEdge Traffic Manager, it is installed and configured and the path between
Traffic Manager and the storage device is functioning.
Follow the instructions in your storage device’s documentation to create and map the logical
volume. For a URL to this storage documentation, see
“Related Documentation” on page 6
■
Completely set up the logical volume. When you are finished, the volume must be created,
mapped, mounted, and initialized.
■
If necessary, partition the volume.
■
To allow multiple clusters and nonclustered nodes to access the storage device, create initiator
groups by using LUN masking.
Are you using multipathing?
■
If yes, proceed to
■
If no, skip to
Are any devices that are associated with the volume you created at an
unconfigured
state?
#
cfgadm -al | grep disk
■
If no, proceed to
■
If yes, configure the Traffic Manager paths on each node that is connected to the storage device.
cfgadm -o force_update -c configure
controllerinstance
For the procedure about how to configure Traffic Manager paths, see the
Sun StorEdge Traffic
Manager Installation and Configuration Guide
.
On one node that is connected to the storage device, use the
format
command to label the new
logical volume.
