Detect Resizing of a Source LUN

Modifying the size of the source LUN requires that you update the source LUN size in your protection plan. Use the Toolkit for MaxRep to adjust the size of the source LUN of your protection plan.

When resizing replication pair LUNs, resize the LUNs in the following order:

Resize the target LUNs
Detect the target LUN resize in the Oracle MaxRep for SAN GUI
Resize the source LUN
Detect the source LUN resize in the GUI

Modify the size of your LUN by following the procedure that is described in the Oracle Flash Storage System Administrator’s Guide.

Navigate to Settings > Oracle Storage > Toolkit for MaxRep.
In the Select MaxRep Option page, select Detect Resize and click Next.
From the Select Oracle Storage list, select the Oracle FS System that contains the source LUN for the replication pair to be resized.
Expand the entry for the Oracle FS System containing the LUN.
From the LUN navigation tree, select the source LUN of the replication pair.
Tip: Click the + sign to expand the list of available LUNs.
After selecting the LUN, click Next.
Confirm that the correct LUN is selected, and then click Submit.
Result:
The system displays the Policy History for LUN Resize page.
Verify that the Policy History status shows Pending, followed by Success.
Click the Monitor tab and review the Alerts and Notifications for possible errors.

If the system displays the following error, then follow the procedure to resize and detect the resize of the target LUN.

The source Device (/dev/mapper/...) has been reconfigured upon resize and the following replication pair is paused. Please resize your target LUN to greater than or equal to the source LUN  and then resume the replication pair.
