Resolution updated, issue fixed in Smart Array firmware version 6.60.
Original Document Release.

In some instances, on HPE Proliant Gen9 servers that use HPE Smart Array Gen9 Controllers with Smart Storage Battery (SSB) backup for the Smart Array Cache Module, a failure of the SSB may result in indications that the smart array cache is permanently disabled if the Smart Array firmware version is older than 6.60. This can result in an incorrect component being replaced. In addition, the SSB status may be displayed as "OK" even when it has failed.

A failed SSB will result in the smart array write cache being disabled. This will not prevent the system from operating, but it will operate at a reduced performance level. This issue will be indicated by the following symptoms:

  • The system health LED will blink amber, indicating the server is in a degraded condition.
  • The Integrated Lights-Out (iLO) utilities (web page and CLI) will show the smart array cache module status as "failed" and the SSB status as "OK."
  • The HP Smart Storage Administrator (HPSSA) and HP Smart Storage Administrator CLI (HP SSACLI) will show the status of the smart array cache as "permanently disabled."


Any of the following HPE Smart Array Gen9 Controllers running with firmware version 6.30 (or earlier):

  • HPE Smart Array P240nr Controller
  • HPE Smart Array P244br Controller
  • HPE Smart Array P246br Controller
  • HPE Smart Array P440ar Controller
  • HPE Smart Array P542D Controller
  • HPE Smart Array P741m Controller
  • HPE Smart Array P840ar Controller


To resolve this issue, update the Smart Array Firmware to version 6.60, which has been modified to indicate that the smart array cache is "temporarily" disabled if the Smart Storage Battery fails. Follow the steps below to obtain the latest Smart Array firmware:

1. Click the following link:

2.Enter a product name (e.g., "P840ar Controller") in the text search field and wait for a list of products to populate. From the products displayed, identify the desired product and click on the Drivers & software icon to the right of the product.

3.From the Drivers & software dropdown menus on the left side of the page:

-Select the Software Type - (Firmware)
-Select the Software Sub Type - (Storage Controller)

4. Select the latest release of RECOMMENDED * Supplemental Update / Online ROM Flash Component - Smart Array Version 6.60 (or later). Note: To ensure the latest version will be downloaded, click on the Revision History tab to check if a new version of the firmware/driver is available.

5. Click Download.

The excerpt below from HPE SSA illustrates how the Smart Array cache status will be displayed if a Smart Storage Battery fails with Smart Array firmware version 6.60 (or later):

Perform the actions stated in this Resolution to determine if the SSB is faulty. As demonstrated above, a failed SSB may be indicated as a "cable error" when reported by the cache module. If the SSB is faulty, replace the part.

NOTE: If the status for the items indicated does not match what is shown in this advisory, but a failure of the cache module or SSB is occurring, then troubleshoot or parts replacements should occur per normal methods.
