Checking LUN Configuration

Anytime you are managing LUNs, you may find it convenient to check the current LUN configuration and
the available capacity.
The current LUN definitions can be seen on the standard "Disk Devices" screen. The available capacity is
displayed as "Unallocated" on the "View Array Status Information" screen. See
Status" in this chapter.

Creating a LUN

Only capacity assigned to LUNs is visible to the HP-UX operating system. When creating LUNs, consider
the following factors:
Any size limitations imposed by the operating system, for example, LVM.
Your backup strategy. If you do unattended backup to a device such as tape, you may want to avoid
creating a LUN that is larger than the capacity of the media. This allows you to backup an entire LUN
without changing media.
Configuring the LUN into LVM for maximum performance as described in
NOTE! Before creating a LUN, check your operating system documentation for any additional
information or steps that may be required to create a LUN.
