A new firmware version (U.01.06) for the RAID 4Si controller is available as a patch from
the HP IT Resource Center (ITRC), at http://itrc.hp.com. This version supersedes
the version (U.01.04) that is currently shipping with the HP RAID 4Si software.
As always we strongly recommend that you upgrade to the latest firmware at your
convenience.
Summary of Changes
• Boot support (new feature)
— Ability to boot over the RAID controller.
— The customer can install the OS onto the logical drives configured on the RAID
controller.
— There is an option now in Ignite-UX called “Configure A5856A” which brings up
the configuration tool called IRM that helps in configuring logical drives.
• OLA/R (new feature)
— Ability to perform Online Addition/Replacement of the RAID controller.
— The customer can do an OLA/R of the RAID controller using SAM or the rad
command.
• New firmware revision (U.01.04) of the RAID controller includes the following new
features and fixes since earlier released version (U.01.01)
— Provides support for disk firmware download.
— Provides capability to handle NVRAM vs. Disk mismatch on replaced boot cards.
— Provides fix for a problem which causes logical drives to become unavailable
when a reconstruction is started from IRM (for example, when changing RAID
levels).
— Provides fix for I/O hang due to cache deadlock.
— Provides fix for the problem of HOTSPARE sometimes not rebuilding when the
disk that is part of the logical drive is pulled out.
— The firmware image a5856a_01_04.img is present in the
/opt/raid4Si/firmware directory on the system on which you install the RAID
software. A help text file, a5856a_u_01_04.txt, for installing the image is
available in the same directory.
• Diagnostic improvements
