Configuration
Manager
Summary:
Familiarize
with the Configuration Manager Graphical User Interface of EMC ControlCenter.
Objectives:
a)
Identify Symmetrix with un-configured capacity.
b)
Create Symmetrix Logical Volumes.
c)
Map Symmetrix Logical Volumes to Front End Director Port(s).
d)
Perform the steps necessary to reconfigure the host to access the newly
mapped Symmetrix Logical Volumes.
e)
Create Meta Volumes.
f)
Change Device Type Definitions.
Configuration
change sessions require exclusive locks on the Symmetrix for the duration of the
change. For this reason multiple change sessions cannot be simultaneously,
initiated on the same Symmetrix.
-
Identify
Symmetrix with un-configured capacity.
-
Select
“Properties” from the Tool Bar and then select Storage from the Tree
Panel. Look for the column “Unconfigured Capacity” in the Target
Panel.
-
Is
there Unconfigured Capacity available on the Symmetrix assigned to your
lab group? What is the Symmetrix Serial Number:_____________, Unconfigured
Capacity: _________________
-
Create
Symmetrix Logical Volumes.
-
Identify
the Primary Symmetrix Agent for your assigned Symmetrix. Select
“Agents” from the ECC Administration drop down menu. Then select your
assigned Symmetrix from the Tree Panel. The primary agent can be
identified by the blue line connecting the host to the Symmetrix.
-
Right
click on your assigned Symmetrix and select Configure followed by Logical
Device Configuration. Configuration lock is acquired.
-
In
the Logical Device Configuration window, enter the required fields as
suggested by your instructor. Verify and select Execute.
-
After
successful completion, verify that the new devices are available by
expanding your assigned Symmetrix in the Tree panel. You should see the
new devices under the Standard Devices folder in the Unmapped Devices.
-
Map
the newly created Symmetrix Logical Volumes to Front End Director Port.
-
Determine
the Front End Director Port(s) your assigned host is attached to. This can
be done using the Path Details view.
-
Select
the device to be mapped in the Tree panel. Then access the icon for SDR
operations from the menu bar. Configuration lock is again acquired.
-
In
the Target pane of the SDR window, select the Front End Director Port to
which you want to map this device. If the automatically selected Target
ID/LUN is not suitable, then double click in the “Address” column to
change the TID/LUN assignment.
-
Execute
the task.
-
In
the Visual Symmetrix view, verify that the device has been mapped to the
Front End Director Port.
-
Reconfigure
host to access the newly mapped Symmetrix Logical Volume(s).
If you are not familiar with Device Masking functions and commands, please
ask your instructor for assistance.
-
Update
the VCM database to enable your host to access the newly mapped device.
-
Perform
any necessary reconfiguration activity on the host to make it recognize
the presence of a new device. This may include reboot.
-
If
possible, run the syminq command on the host to verify access to the
assigned Symmetrix Logical Volume.
5.
Create a Meta Volume.
-
Select
your assigned Symmetrix in the Tree panel, and then access the icon for
Meta Device creation from the menu bar. Configuration lock is acquired.
-
Select
the meta device members in the Source pane of the Meta Device
Configuration window. Select the type of meta device “Concatenated” or
“Striped” in the Target pane. Next select “Execute”.
-
Verify
successful creation by looking in the Meta Devices folder under the
Unmapped Devices folder of your assigned Symmetrix.
-
Change
device type definition.
-
Right
click on your assigned Unmapped Standard device and access Configure ->
Device Type Definition. Configuration lock is acquired.
-
Select
the device in the Edit view of Device Type Definition window. Select the
appropriate action. Choose BCV, as we want to change the Standard device
into a BCV. Note that the type immediately reflects BCV, however
change is not committed until “Commit” is selected.
-
Verify
successful conversion by looking for your device under BCV Devices in the
Unmapped Devices folder of your assigned Symmetrix.
END
of exercise.
Good
Luck!
