Code update for the Windows environment
The IBM System Storage DS Storage Manager (using the Installation wizard
InstallAnywhere) supports an installation upgrade. Launch the installation program and it
automatically upgrades all the components that you previously installed. For details about the
installation procedures, see 4.7, “Installing IBM System Storage DS Storage Manager” on
page 152.
Code update for the Linux environment
You can update the host-based DS5000 storage subsystem software for Linux either with
InstallAnywhere or manually. See the readme of the host software for a detailed procedure.
The steps below explain the manual update procedure for all hosts running with RDAC:
1. Uninstall the earlier version of Storage Manager components.
2. Install SMruntime.
3. Install SMclient.
4. Disable and enable the Event Monitor.
5. Install the IBM FC HBA non-failover version device driver for Linux.
6. Install Linux RDAC.
7. Install SMagent (optional).
8. Install SMutil.
9. Make sure that the correct host type is specified.
To update the Linux environment with IBM HBA failover driver as a multipath device driver,
you must perform these steps:
1. Uninstall the earlier version of Storage Manager components.
2. Install SMruntime.
3. Install SMclient.
4. Disable and enable the Event Monitor.
5. Install SMutil.
6. Uninstall the existing IBM DS5000 Management Suite Java.
7. Install the IBM FC HBA failover version device driver for Linux.
8. Install the IBM DS5000 Management Suite Java and QLRemote Agent.
9. Configure path failover/failback. See the device driver readme file for detailed information.
7.1.5 Updating controller firmware
You can transfer the controller firmware and NVSRAM to a designated flash area on the
DS5000 storage subsystem controllers and activate it at a later time, or transfer the files and
apply them at the same moment.
The firmware is transferred to one of the controllers, which then copies the file to the other.
The image is verified through a CRC check on both controllers. If the checksum is okay, the
uploaded firmware is marked as ready and available for activation. If one of the two
controllers fails to validate the CRC, the image is marked as invalid on both controllers and is
not available for activation. An error is returned to the management station as well.
For information about how to use the IBM System Storage DS4000 Controller Firmware
Upgrade Tool to upgrade your DS4700 Express controller firmware from 06.xx to 07.xx, see
7.1.6, “Controller Firmware Upgrade Tool” on page 339.
Important: Always check the readme files of the firmware you are going to install for
prerequisites before proceed with the update.
