Steps For Upgrading From Ds4300 Model 6Lu/6Lx To Model 60U/60X - IBM TotalStorage DS4300 Installation, User's, And Maintenance Manual

The upgrade kits contain two DS4300 controller CRUs, with cache memory battery
installed, and one power supply. You must purchase additional SFPs and fibre
channel cables separately to make fibre channel connections to the host ports on
the second DS4300 controller.
Use the following procedure for both upgrade kits.

Before you begin:
v Schedule downtime for the upgrade.
v If you purchase additional storage capacity at the same time as the controller
v If you have premium features enabled in the existing DS4300 storage subsystem,
v Ensure that you have installed the latest version of DS4000 Storage Manager.
v Use the Storage Manager Client to determine whether the system is in an

upgrade kit, do not connect the new drives or storage expansion enclosures to
the DS4300 controllers until you complete the following tasks:
– Finish the upgrade process
– Verify that the upgraded storage subsystem is in optimal state
ensure that you have access to the premium features key files before you begin
the upgrade process. You will need to re-enable your premium features during
the process.

controllers will change. If you have any applications that rely on the previous
WWNNs, such as FC switch zoning definitions, you must update the applications
with the new WWNNs.
1. In the Storage Manager Client, open a management connection to the DS4300
that you are upgrading.
2. Save the storage subsystem profile to a disk location that is not in the DS4300
that you are upgrading. In the Subsystem Management window, select View
—> Storage Subsystem Profile. When the Storage Subsystem Profile
window opens, click Save As. The Save Profile window opens. Select an
appropriate directory and choose a file name for the profile, then click Save.
Click Close to close the Storage Subsystem Profile window.
3. Complete any necessary server preparation tasks, because the disks will not
be available during the upgrade process. For example, stop all programs,
services or processes in the host servers that access the logical drives.
Note: Make sure that you stop any background programs, services or
processes that write data to the logical drives. For example, Microsoft
MSCS periodically writes to the Quorum disk.
4. Stop I/O to the storage subsystem.
5. Unmount any mapped LUNs from the storage subsystem.
