This document explains how to install batteries, download firmware into a disk array controller, and how to
replace an array controller.
About Battery Packs
If your disk array goes without power, the controller batteries are capable of retaining data in NVRAM for a
minimum of one week. Always perform a successful Shutdown before replacing the batteries. For further
protection, battery packs should be replaced one at a time, so that there is always at least one battery
providing power for memory backup. If the disk array power is to be turned off for an extended period of
time (more than five days), then the NVRAM memory maps should be saved to disk (by successful
Shutdown) and both battery packs should be disconnected to prevent damage to the battery packs and the
controller.

  • Page 1 HP SureStore E Disk Array 12H Controller This document explains how to install batteries, download firmware into a disk array controller, and how to replace an array controller. About Battery Packs If your disk array goes without power, the controller batteries are capable of retaining data in NVRAM for a minimum of one week.

  • Page 2: Installing Controller Batteries

    Installing Controller Batteries Two battery packs, part number 1420-0532, must be installed in each controller module before the module can be used. Two battery packs are shipped with each new controller module. In the disk array shipping carton, the batteries are located in a cardboard sleeve next to the array controller. To install the controller battery packs, do the following (see Figure 1): If the battery cover latch is not already removed, press down on the battery cover latch.

  • Page 4 Replacing Controller Batteries This procedure is different than installing batteries the first time the disk array is used, since replacing batteries assumes that you have valuable data stored on your disk array. Many factors affect battery life, including not only time of battery use, but also time of battery storage. Controller batteries should be replaced every three years, or sooner if the display module indicates a constant “Battery Discharged”...

  • Page 5: Before Beginning Firmware Download

    Downloading Array Controller Firmware When two controllers are installed in the disk array enclosure (dual controllers), both controllers must have the same version of firmware. If you update (or download) new firmware, the new firmware is copied to both controllers. When a controller is replaced, however, the replacement controller may have a later version of firmware than the currently installed controller.

  • Page 6: Other Considerations About The Firmware Download Process

    Other Considerations About the Firmware Download Process NOTE! For Windows NT Systems: Since the Download utility does not support long directory names, it is better to change to the directory where the firmware is located first, and then the <codefilename> is simply the filename of the firmware. Otherwise, a path with a directory named “Program Files”...

  • Page 7: Firmware Download Procedure

    Firmware Download Procedure See the flowcharts (Figure 2 and Figure 3) to determine which download procedure to follow. Pick the appropriate procedure. NOTE! This procedure assumes that the Model 12 and HP SureStore E Disk Array 12H controllers have been updated to at least HP25 and HP24 firmware revisions, respectively. If they have not been updated to these versions of firmware, then refer to the service notes indicated below to update the array before continuing.

  • Page 11 Download Windows NT AutoRAID Manager includes a separate utility for downloading controller firmware. This utility, WinDownload, simplifies the process of downloading new firmware to the controller in your disk array. The WinDownload utility is used only for downloading firmware to the disk array controllers. Firmware can also be downloaded to the disk modules using the ARM download command line utility described in the System Administrator’s Guide, which is shipped with each disk array.
  • Page 12 Download A) Downloading Disk Array Firmware from a File Using ARMServer (AutoRAID Manager) CAUTION! Controller firmware HP4x and any later versions have a different data map format in NVRAM memory. Once you have HP48 or later, you can not “downgrade” to any firmware version prior to HP4x without first completely backing up all data on the array, including any meta-data, e.g., LUN and LVM configuration.

  • Page 19 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.
