I'm monitoring my IBM ServeRAID M5015 controller for RAID status with MegaCLI, I have this on one of the disk :
Enclosure Device ID: 252

What does this mean exactly ? I can't find an exact description, is there a way to have more details ? The RAID array has the Optimal state.
Media Error Count: 32
Predictive Failure Count: 18
Is there a way through the CLI to power-on the front LED so I physically know which disk I need to replace ?
Best Answer
There are errors on your disk. S.M.A.R.T. stands for Self-Monitoring, Analysis and Reporting Technology
The specific errors you mention correlate to mechanical degradation of the drive. You can possibly use this report to obtain a warranty replacement fomr IBM. The drive WILL eventually fail.
