EMC CX700 Wrong Information

Hello everyone,

I've been trying out OpStor for my company for the past few days; we have a couple of CX700 and last Saturday we had to replace a faulty disk in one of the arrays, today while checking OpStor I saw that the disk replacement had affected my weekly uptime by 5% (3h45m).

I'm not sure if this is supposed to work like this or what.

Any help would be greatly appreciated, this might influence my manager to purchase the software or not.
