The action we are performing above instructs the system to use mdisk7 as a faster disk. The
IBM Flex System V7000 Storage Node will then move highly utilized storage extents to this
MDisk.

8.2.5 Additional actions on MDisks
Here are some of the additional actions that can be performed on MDisks. Such actions can
be performed by clicking Pools
be performed by clicking Pools
MDisks by Pool
Actions or right clicking the selected
MDisk.
��
Detect MDisks: The Detect MDisks button at the upper left of the MDisks by Pools
window is useful if you have external storage controllers in your environment. The Detect
MDisk action initiates a rescan of the Fibre Channel network. It discovers any new MDisks
that have been mapped to the IBM Flex System V7000 Storage Node storage system, and
rebalances MDisk access across the available controller device ports. This action also
detects any loss of controller port availability, and updates the IBM Flex System V7000
Storage Node configuration to reflect any changes.

When external storage controllers are added to the IBM Flex System V7000 Storage Node
environment, the IBM Flex System V7000 Storage Node automatically discovers the
controllers and the LUNs that are presented by those controllers are listed as unmanaged
MDisks. However, if you have attached new storage and the IBM Flex System V7000
Storage Node has not detected it, you might need to use the Detect MDisk button before
the system detects the new LUNs. If the configuration of the external controllers is
modified afterward, the IBM Flex System V7000 Storage Node might be unaware of these
