I'm familiar with the MegaRaid Storage Manager as I used to manage a lot of JBODs with it. &nbsp;Is there any way to get down to &nbsp;the bios level RAID controller instead, and see if you can fix things there???

Thanks Dazer,<br />
<br />
That was going to be my next step. I was hoping to avoid rebooting the server (it's our exchange server). I'm going to try a simple reboot first. See if that &quot;resets&quot; the controller. If the logical drive still says degraded after that I will go into the bios and see what I can try there.

What steps did you go through to remove the bad drive? &nbsp;MegaRAID has some specific steps to go through to &quot;mark as bad...&quot;

Hello clifford_m71, <br />
<br />
I may have gotten this wrong, but by 'offline', did you power off the server? &nbsp;It does not sound like it as this is your Exchange server, but i wanted to make sure. &nbsp;Failed HDDs must be replaced while the Array Controller is alive.<br />
<br />
Just wanted to be sure...<br />

There was an oversight on my part. I was using the wrong size hard drive when trying to rebuild the array.

I have a server with a ServerRAID M5014 controller and I manage it using MegaRaid Storage Manager.<br />
<br />
I have two virtual drives set up. <br />
<br />
Drive Group 0 utilizes physical drives in slot 0 and 1 and is RAID 1 for the OS.<br />
<br />
Drive Group 1 utilizes physical drives in slots 2-7. The drive in slot 7 was a dedicated hot spare and it failed. I took the drive offline and removed then inserted a new drive. I tried to make it a dedicated hot spare on Drive group 1 but it only gives me the option of making it a dedicated hot spare on Drive Group 0. I can make it a Global Hot Spare but when I do that Drive Group 1 still says it's degraded? I'm at a loss. What am I missing????<br />
<br />
Thank you in advance for any and all help.

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
