Adding devices to a CLARiiON metaLUN for a host

This example demonstrates how a storage administrator uses Ionix ControlCenter to

add devices to (expand) a metaLUN on a CLARiiON CX600 array. MetaLUNs are groups

of striped or concatenated LUNs that can be easily created or expanded using the

Ionix ControlCenter Expand Storage Wizard. The administrator uses metaLUNs as a

way of managing groups of devices based on the type and amount of storage required

by various business applications.

In this scenario, the administrator has received a free space alert that a logical volume

on an AIX host has reached a critical space threshold with only 5 percent capacity

remaining.

Note: Refer to “Preventing a space shortage on a host logical volume” on page 88 for

details on how to configure and respond to free space alerts.
