Expanding the PowerVault NX3500 Storage Capacity
You can expand the storage capacity of your system without affecting the
services to the clients. However, the process occurs over a period depending
on the total number of the existing and added LUNs, the total storage
capacity, and system workload.
You can add additional LUNs from the storage capacity that is already
available on your storage array to the PowerVault NX3500 system.

Prerequisites

This procedure requires a management workstation with the following
functionalities:
• Modular Disk Storage Manager Software (MDSM) is installed and has
available storage capacity that can be allocated to the PowerVault NX3500.
• The PowerVault NX3500 NAS Manager web interface is deployed.
• Is located on the LAN/client network.
To expand the PowerVault NX3500 storage capacity:
1
Create a Disk Group from the unconfirmed capacity on the MD storage
array that is providing storage to the PowerVault NX3500. See "Creating
Disk Groups" on page 46.
