Determining which HPCISSS2 and HPCISSS3 drivers to install

Symptom

Unsure which HPCISSS2 and HPCISSS3 drivers SUM installs.

Action

If you are updating the Smart Array SAS/SATA driver, use the following table to determine which driver SUM installs if you select both the HPCISSS2 and HPCISSS3 drivers on the Review/Deploy screen:

Installed driver version	CISSS2	CISSS3
HPSAMD driver	Installs if only this driver is selected.	Installs CISSS3 if both drivers were selected.
HPCISSS2 driver	Installs and updates.
HPCISSS3 driver		Installs and updates.

SUM does not overwrite an HPCISSS3 driver with HPCISSS2, or HPCISSS2 with HPCISSS3. After an update, SUM displays that the HPCISSS3 driver overwrote the HPCISSS2 driver, or HPCISSS2 overwrote HPCISSS3. When you relaunch SUM, it displays that the driver did not install and is ready to install.

If you want to install a specific driver and SUM installs the other driver, perform an update outside of SUM to install the selected driver.
