Upgrade the firmware of SAS HDD on DL380 G5

Fran Garcia is correct, you can't just pick your own SATA disks with those controllers - HERE's the quickspecs to help you choose the correct disk part numbers.

You're correct. Firmware version 7.24 is the current release.

If you have the downtime window, power the server off entirely (remove power cables), wait a few minutes, and power up again. See if that jump-starts the battery charge process.

But short of that, if your system is still under warranty (P400-equipped systems went away in 2009), call for another battery unit. Sometimes HP technicians grab components from the wrong bin at the parts depot.

HP isn't in the battery business much anymore... The two most recent generations of HP Smart Array controllers can use flash-backed cache, which eliminate the impact of cough battery malfunction.

HP can analyze the battery status using a dump from the HP Array Diagnostic Utility (HPADU), but for a disposable part, it's better for everyone involved to just try a new unit.

Finally, if you're experiencing an unbearable drop in performance because of the dead battery, you can override the cache disablement. Look for the No-Battery Write Cache: Enabled option.
