Installation instructions


If your PowerVault MD3200/MD3220-series storage array is currently running a firmware version lower than, you cannot directly install the RAID controller firmware version included in this release. 

Instead, you must first install the bridge firmware version After the bridge firmware is successfully installed, you can then install RAID controller firmware

Specifically, follow these steps:

1. *** IMPORTANT *** Install Dell PowerVault MD Storage Manager (MDSM) software from the Resource DVD version or higher.

2. Extract the following files from the archive:
   * Bridge_Firmware_07_75_28_60.dlp
   * MD3200_MD3220_Firmware_07_80_62_60.dlp
   * MD3200_MD3220_NVSRAM_N26X0-780890-001.dlp

3. Download and activate RAID controller bridge firmware version (contained in the Bridge_Firmware_07_75_28_60.dlp file)

4. Once the bridge firmware installation is successfully completed, wait at least 30 minutes to allow the attached hosts to re-discover the storage array.

5. Download and activate the RAID controller firmware version (contained in the MD3200_MD3220_Firmware_07_80_62_60.dlp file) together with the NVSRAM configuration file version N26X0-780890-001 (contained in the MD3200_MD3220_NVSRAM_N26X0-780890-001.dlp file).
