Presenting the Dell AX4-5F LUNs to CommVault Simpana 
This section explains the configuration steps required on the DL Backup to Disk Appliance to present 
the LUNs on the Dell AX4-5F Array to CommVault Simpana 
1.  Once the DL Backup to Disk Appliance has rebooted after the install of EMC PowerPath, click 
Start -> Administrative Tools -> Server Manager -> Storage -> Disk Management. The LUNs 
are listed as available disks. 
2.  Initialize the required disks as a GPT. (GPT disks use the GUID partition table and allows for 
volume sizes of greater than the 2TB limitation of MBR disks). 
3.  Create a Simple Volume on the disk. 
4.  Assign a drive letter to the volume. 
5.  Quick Format the volume. 
6.  Repeat this process for each LUN the DL Backup to Disk Appliance will use as a backup target 
7.  The volumes will now be available for creating Simpana Magnetic Libraries. (For more 
information on how to configure Libraries & drives, please refer to the “Library and Drive 
Configuration - How To” section in the CommVault Books Online documentation)
