HP P6000 EVA Updating Product Software Guide (XCS 11001100) (5697-2328, November 2012)

2 Preparing for the upgrade
HP recommends that before starting the XCS upgrade, you perform tasks listed in Table 2 (page
9) to minimize the time required to complete the upgrade. The tasks you perform depend on your
system configuration and the HP P6000 Command View implementation. These tasks focus on
upgrading system components to ensure they meet the supported configuration for XCS 11001100.
NOTE: Be sure to record the XCS controller software version you are using. You will need this
information in the event that you must restore your XCS controller software. To create a restore
CD, see Creating a CD from the XCS Controller Software .ISO Image Read This First for your array
model (HP P6000 EVA or HP EVAx400).
