Info: I have a LSI 9265-8i controller. It's been running pretty well for two years. More recently it looks like a drive may be failing - no errors reported and no media issues reported when viewing "MegaRAID Storage Manager". Performance on one of the virtual drives is quite bad. I ran "MegaCli -AdpEventLog -GetLatest 1000 -f events1000.log -aALL" and looked at the output. There are some "unexpected sense" logs around two months ago. I have no idea what they mean. Code: 0x00000071 Class: 0 Locale: 0x02 Event Description: Unexpected sense: PD 09(e0xfc/s0) Path 4433221103000000, CDB: 28 00 9d 96 dc 89 00 00 77 00, Sense: 3/11/00

Event Data:

So to my question: How do I use MegaCLI to understand which drive is failing if any? Are there good reasonably-priced tools I can purchase to tell me something useful?

Now for my moan: Why don't LSI include decent reporting and diagnostics into their management tools?
