Unity Connection server MCS-7845-H2-ECS4 hard drives only half have power

[nn7963]

I have 2 servers MCS-7845-H2-ECS4 which each have 8 hard drives. the 4 hard drives on the left are not powered up on either server. The last 4 hard drives all have green power lights. Is this normal operation? I thought I might have a failed controller in the first server and I ran over to check the other server, but its hard drives were exactly like the primary server. The server is running Unity Connection 7.1(5).

I checked them with the RTMT tool and I don't see any alerts about any failed hard drives or controllers. Please help

Hi there,

I believe everything is working as designed We don't

run those exact models but there is a reference here

about removing 4 HDD's (out of 8) here;
