Allocating CLARiiON devices (LUNs) to a host 159
Configuring and Controlling Your Datacenter
◆ Finds available LUNs
◆ Adds LUNs to the storage group
Determining if storage group exists
The LUNs will be placed in a storage group for the host. Only one storage group can
exist per host. The administrator determines that a storage group already exists by
selecting the host in the Console tree, and selecting Storage Allocation, Path Details
in the toolbar. Figure 140 shows that the existing storage group is named
l82ar136_AIX.
If this host did not have a storage group, the administrator could have created a new
one by right-clicking Storage Groups under the CLARiiON array in the Console tree and
selecting New. This displays the Storage Group Configuration Wizard.

Finding available LUNs
The administrator finds the available (unmapped) LUNs on the array by right-clicking
Unmapped LUNs under the CLARiiON array in the Console tree and selecting
Properties.
Host l82ar136 requires 10 GB of RAID 5 storage. LUN 1 will meet host’s needs as
shown in Figure 141.
