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.
