on a HP Proliant ML 350 G4p are installed and configured 4 hard disk SATA in RAID 5 mode. Two of the four hard disk have green LED blinking irregullary, one off and another green LED ON without blinking.
I look for this behavior and I read on HP documentation this info (HP link)
[Online/activity LED (green)] On
[Fault/UID LED (amber/blue)] Off
[Interpretation] The drive is online, but it is not active currently.
I think only two disks are working and then RAID 5 configuration is not complete or do not works well; what is meaning of online respect active in this case?
What do you think about?
