HP ProLiant Storage Server SAN Connection and Management Application Notes (5697-6495, September 2007)

Figure 1 Expanding a LUN (S mart Array only)

NOTE:

The Expand Array task is listed only if there is an unassigned physical drive on the controller. The

unassigned drive must also have a capacity no less than that of a drive in an existing array. If these

conditions are not fulﬁlled, install at least one suitable drive on the controller, and then click Refresh.

There are two scenarios to adding storage for array expansion (Smart Array storage only):

• Add an unassigned physical disk to the array.

• Add a new disk to the appropriate storage device.

Expanding the logical drive

This option in the ACU increases the storage capacity of a logical drive by adding unused space on an

rray to the logical drive on the same array. The unused space is obtained either by expanding an array,

or by deleting another logical drive on the same array.

There are two scenarios to adding storage for logical drive expansion (Smart Array storage only):

• Extend an existing storage LU N where space is available in the array.

• E

xtend an existing storage LUN where space is not available in the array (Smart Array only).
