14.5 Download firmware
In this section we describe the steps to upgrade the DS3500 storage subsystem firmware and
NVSRAM microcode. You can download the latest firmware at:
http://www.ibm.com/servers/storage/support/disk
Appendix A, âIBM Support Portal web siteâ on page 737 describes this Web site and its
contents.
On the same Web page you can select (for example, as shown in Figure 14-32, for the
DS3500) the firmware (controller firmware and NVSRAM, ESM and disk firmware), HBA
device drivers and firmware, RDAC multipath drivers and the DS Storage Manager
application. Also, the links for the product documentation, troubleshooting tips, and all other
information regarding DS3500 are available on this site.
Figure 14-32 Code downloads for DS3500
The DS3500 firmware version is closely connected to the Storage Manager version, and HBA
device driver and firmware available for your hosts. You should always check the DS3500
firmware readme and change-history files to see if there are any host software dependencies.
If there is newer version of Storage Manager (including multi-path device drivers) or HBA
software required for the hosts, download and install these first before updating the DS3500
firmware. ESM firmware should also be upgraded to the required level before starting the
controller firmware upgrade. In general, we recommend running at the latest levels unless
specifically advised otherwise.
Download all the packages you will need from the IBM Support Web site and store them
unzipped on a local disk.
Note: Updating firmware will normally require a maintenance window, so it is better to plan
an appropriate outage time in advance.
