I have a D2600 filled with 12x2TB 7200RPM HP SAS drives. The drives are the original ones that the array was delivered with, and I bought it used from a refurbisher. These are genuine HP drives.
When it's starting up the fans go to 100% (this is normal), then suddenly down to silent levels, then ramping up to 100% again. It stays like this forever, with an amber fault-LED and a green health-LED.
No individual components show any sign of error, everything is lighting up green. I/O modules show address 01. Disk array works with the connected DL380 G6 housing a HP P410i RAID card. I've got the disks setup in RAID5 with 18TB of total storage. Runs fine, no write/read problems. I've tried with different I/O modules, PSUs and without disks. Removing the fan modules gives a health error, obviously.
There seems to be no problem with it what-so-ever, but it keeps complaining about something. I could suspect a temperature sensor or a faulty temp readout from any of the drives, but I'm not sure. No errors on POST and in the RAID BIOS, iLO sees the disks as healthy and no further info.
I've tried removing all the drives, and inserting them one by one, even re-arranged and re-configured them since there's no data on them yet.
What could be the culprit? How do I diagnose this DAS? I don't mind the noise it makes since it's in a dedicated server room for my homelab, but I'm worried the fan modules (and PSU fan) might fail after a while.
Thanks in advance.
