8 years ago I added naive support for the 3ware RAID utility (tw_cli) in the attached patch.
It displays specs, battery, logical and physical devices. Tested on a 3Ware
9650SE-8LPML and 9690SA-8I using the tw_cli versions 2.00.11.016, 2.01.09.004,
2.00.09.012.
Issues that I didn't address:
- It only polls the first controller (c0); it would be more work to poll the
list of controllers and then iterate over them, and I don't have a need for it.
- Cache memory size is listed in 3ware docs as 'available memory' and is never
exactly equal to the installed memory. I don't know why, maybe this is actually
the unused portion of the card's cache?
- The cards I have don't seem to periodically run the battery test by
themselves, so the hours remaining printout will be zero if the scan has never
run (and likely inaccurate if it hasn't run lately).
- I didn't parse out what the unit cache value means (Ri = intelligent read, R
= basic read, W = write; you'll commonly see RiW).
- I think older versions of tw_cli do not display physical devices in the same
format, which will cause weirdness.
Output on a controller testing its battery looks like this:
Controller | 3ware Inc 9690SA SAS/SATA-II RAID PCIe (rev 01)
Specs | 9690SA-8I, 448MB cache, Optimal
Battery | State: Testing (0 hours backup), Volt/Temp/Ready: OK/OK/No
