Before expansion, make sure that the storage system meets the expansion requirements. Obtain and record necessary information, including the IP address of the application server that uses the LUN, the WWN of the LUN, or the host LUN ID.

Locate the LUN to be expanded.

Before expanding LUN capacity, confirm information about the LUN that carries service data to ensure a successful expansion.

Expand LUN capacity on the storage system.

Expand the LUN online to the required capacity.

Expand storage space for the application server.

After the expansion, scan for disks on the application server to detect and use the expanded LUN.

Hy, it's quite simple.
Just make sure storage pool has enough space that you want to add to the LUN.
In the device manager, go to LUNs list, locate the LUN that you want to expand, click on the LUN once, on the top list a button "expand" will appear.
Click the expand button and choose the new capacity.
And that's pretty much it.
Let me know if you need more help.
