IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User's Guide
The upgrade kits contain two FAStT600 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 FAStT600 controller.
Use the following procedure for both upgrade kits.
Steps for upgrading from FAStT600 Model 6LU/6LX to Model
60U/60X
Before you begin:
v Schedule downtime for the upgrade.
v If you purchase additional storage capacity at the same time as the controller
upgrade kit, do not connect the new drives or expansion units to the FAStT600
controllers until you complete the following tasks:
– Finish the upgrade process
– Verify that the upgraded storage server is in optimal state
v If you have premium features enabled in the existing FAStT600 storage server,
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.
v Ensure that you have installed the latest version of FAStT Storage Manager. For
more information, see the IBM FAStT Storage Manager Installation and Support
Guide for your operating system, or see the following Web site:
www-1.ibm.com/servers/storage/support/fastt/index.html
v Use the Storage Manager Client to determine whether the system is in an
optimal state. If it is not, fix the problem to return the system to an optimal state
before you attempt the upgrade.
v After the new controllers complete the boot process, the WWNN of the FAStT600
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.
Complete the following steps to upgrade from FAStT600 Model 6LU/6LX to Model
60U/60X, using either the standard or the Turbo option upgrade kit:
1. In the Storage Manager Client, open a management connection to the
FAStT600 that you are upgrading.
2. Save the storage server profile to a disk location that is not in the FAStT600
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 server.
5. Unmount any mapped LUNs from the storage server.
