Figure 13-17 Download Firmware
The four options are:
򐂰 Download Controller Firmware
Includes the controller firmware of the storage subsystem
򐂰 Download Controller NVSRAM
The NVSRAM is similar to the settings in the BIOS of a host system. The controller
firmware and the NVSRAM are closely related - be sure to install the correct combination
of the two packages.
򐂰 Download Drive Firmware
Includes the firmware of the hard disk drives
򐂰 Download Environmental (ESM) Card Firmware
Includes the firmware of expansion enclosures.
Before starting to update a storage subsystem:
1. make sure that the system is in the Optimal state (see 9.1, “Status Box” on page 201). If
not run the Recovery Guru to diagnose and fix the problem before proceeding with the
upgrade.
2. Always read the readme file before upgrading any firmware to check for compatibility with
your system.
3. Take care with dual controller configurations. The upgrade procedure needs two
connections to your storage server, one to each controller, it is not possible to perform a
microcode update with only one controller connected. Therefore, both controllers must be
accessible, either in-band or out-of-band, and both controllers be online. If you upgrade
redundant configurations in-band make sure that a multi-path driver is installed on the
management host. This is necessary since the access logical drive moves from one
controller to the other during this procedure and the DS3000 must be manageable during
the entire time.
Note: Download in these links means to update the actual firmware on the hardware.
Before starting any of these operations, you need to have already obtained the appropriate
code from the IBM Web site.
