I wanted to know if a certain server had a Battery Backed Write Cache module (BBWC) on it’s array controller.
I suspected it did not, but I had to be sure. Since this server was running production I couldn’t open (Visual Inspection) or reboot it.
The server didn’t have Insight Agents installed so I couldn’t query it via iLO or the Insight Agents webpage either.
I knew that when you do a full install of the array controller bundled software it comes with a commandline tool, hpacucli.exe.
I decided to see if I could find out with this tool, so I went to this HP Smart Array P410i Controller download page.
From the “Software – System Management” section I downloaded the “HP Proliant Array Configuration Utility for Windows“:
Then I extracted the files to a temporary location:
Inside was an MSI file, HPACUCLI875120.msi. I extracted the files from this MSI:
1 | msiexec /a HPACUCLI875120.msi /qb TARGETDIR=MyFolder |
This extracts the tool and some dll’s to MyFolder\Program Files\Compaq\Hpacucli\Bin.
I copied these files to the server and ran hpacucli.exe. The ctrl all show config command can be used to show all controllers (in my case just one):
Controller details can be queried using “ctrl slot=X show“:
The Battery Count is 0 so we have no BBWC. If you do have a BBWC the following lines are shown (the read/write ration may differ of course):
1 2 3 4 | Accelerator Ratio: 25% Read / 75% Write Cache Backup Power Source: Batteries Battery/Capacitor Count: 1 Battery/Capacitor Status: OK |

The hpacucli download page URL is gone.
The newest *nix equivalent I could find is available at https://support.hpe.com/hpsc/swd/public/detail?swItemId=MTX_d6ebba0f5cd642edace4648b9a.
