Hard disk failed on PowerEdge 2900

Hello,

 

One of RAID 5 hard disks in Dell PowerEdge 2900 failed and server has “Dell PERC 5/i Integrated Controller”. RAID 5 was built by 4 hard disks and each has 300 GB. But, logical disk formed by RAID 5 is about 560 GB. According to RAID 5 calculation, the capacity of logical hard disk should be about 900 GB since it is built by 4x300GB hard disks. It seems to me that one of the hard disks in RAID 5 is being used for “hot spare”. Is it correct?

 

We have “Dell Server Administrator version 4.5.0” installed on that server but it can’t display any information like RAID configuration, hot spare, etc. I am going to install “Dell Server Adminitrator version 5.2.0, A00” which will give more information, hopefully.

 

I’d like to ask the following questions.

 

1. If one of RAID hard disk is hot spare, is there step by step guide for replacing failed hard disk with new one?
2. If there is no hot spare, is there step by step guide for replacing failed hard disk with new one?

 

Many thanks.
