Hi, We have about 15 R820's . We have noticed on 3 of them, that the Power lights for the disks are not on (green), but blank.
There appears to be nothing wrong with these 3 servers. The O/S is fine on them (Redhat) and when a command is given, the disk activity lights flash away, but the power led on the disks (next to the activity led) are just blank.
We updated the f/ware on one of the boxes to the latest and greatest, but still blank leds for disk power. We have 16 disks per server.
Anyone got an idea what can be checked to see why this is happening??
Our other r820s are all fine with the power leds steady on all disks.
Thx, John Bradshaw
