Storage arrays
Supported storage arrays
Metro node supports a variety of storage systems and third-party arrays. For an up-to-date list of supported arrays and other
components, see the Simple Support Matrix for metro nodedocument, available on Dell EMC Online Support and on the SolVe
Online.
Using the Storage Arrays view
Metro node automatically discovers storage arrays that are connected to the back-end ports. All arrays connected to each
director in the cluster are listed in the Storage Arrays view. In some cases you may need to rediscover the storage array, if for
example:
● The array was not discovered correctly (you do not see the expected number of logical units on the array when you view
logical units for the array).
● You made changes to the storage exported in a previously discovered array.
Arrays are sorted by name, in ascending alphabetical order. The arrow in the column indicates the direction of the sort;
ascending ( ) or descending ( ). You can sort columns of data, select one or more arrays in the list, and show or hide
properties on the screen.
This screen shows the following information about storage arrays:
Column
Description
Storage Array The name of the discovered storage array.
Connectivity Status Indicates if the directors have at least one path to both of the array's controllers.
Storage array connectivity status provides more information.
Logical Unit Count The number of LUNs exported from the array.
Auto Failover Indicates whether metro node will trespass the LUNs after a controller failure. This
attribute is reported from the array, and displays only for active/passive and explicit
ALUA arrays.
Storage Arrays Properties Panel
This screen also displays the properties of the storage arrays in a separate panel at the extreme right side of the screen.
Tasks in this Screen
In the Storage Arrays view, you can also do the following:
● Search for an extent — Click the
icon corresponding to the element and type the full or the partial name in the field that
appears. Press Enter.
● Refresh screen data — Click the Refresh icon .
● Create virtual volumes — Select a storage array, and then click CREATE VIRTUAL VOLUMES to start the Create Virtual
Volumes wizard.
● Claim storage — Select a storage array, and then click CLAIM STORAGE to start the Claim Storage wizard.
● Set thin rebuilds — Select a storage array, select MORE > Set Thin Rebuild.
● Show logical units for an array — Select a storage array and select MORE > Show Logical Units. If you do not see the
expected number of LUNs, rediscover the array.
● Rediscover an array — Select a storage array, and select MORE > Rediscover Array to rediscover the array that might not
be displayed correctly.
● Forget storage — Select an array, and select MORE > Show Logical Units. On the Show Logical Units screen, select the
LUN, and click Forget Unreachable LUNs.
