Prerequisites
This white paper assumes that the DL Backup to Disk Appliance has already been configured. The
following prerequisites must be met before initiating an upgrade of the operating system:
 Windows Server 2008 x64 – Service Pack 2 (SP2)
 For Simpana 8.0, Service Pack 6 (SP6) must be applied
 For Simpana 9.0, Service Pack 2 (SP2) must be applied
o
All Auto Updates should have also been applied
 It is recommended that all disk storage should be provisioned prior to the upgrade.
Note: On the DL2200, CommVault automatic disk provisioning fails under Windows Server 2008 R2
when using any versions prior to CommVault Simpana 9.0. With these versions of CommVault
Simpana, you must add new storage to the appliance manually as documented in the Dell
PowerVault DL Backup to Disk Appliance Powered by CommVault Simpana User’s Guide.
IMPORTANT: Upgrading the operating system on the DL Backup to Disk Appliance to
Windows 2008 R2 before meeting the specified prerequisites can potentially lead to data
loss.
