Controller HP SureStore E Disk Array 12H Controller Firmware Download Procedure 23. You are now at a point in which the drives need to be re-installed. The drives were disconnected earlier to further protect the NVRAM. The NVRAM is very important. NVRAM stores all configuration and meta-data that point or map drive location information to real data. If this procedure has been successful up to this point, the correct NVRAM memory maps are located in both controllers and also in the disk drive modules. If the NVRAM is located in both the controllers and the disk drive module correctly (there were no errors encountered during this procedure) Then do the following: • Push on/off button to the off position • Plug in all drive modules • Push on/off button to the on position and wait for the initialization to complete. If you are unsure that the NVRAM is correct in both controllers, there were errors, especially errors like No Address Map or NVRAM errors. Then do the following: • Push on/off button to the off position • Remove both controllers from slot X and Y and reset (disconnect and then re-connect) both batteries at the same time on each controller. • Re-install both controllers. It doesn't matter which controller goes into which slot at this time. • Plug in all drive modules • Push on/off button to the on position and wait for the initialization to complete. 24.

This command can take a few seconds to execute. Once re-connected, you will "see" the array again. 51
