Drive went bad in my Raid 5 setup

[Chris Holub]

Please help,
I have a Netserver LP2000 r with 4 drives configured in Raid 5. 1 drive went bad so I ran it on 3 drives my new one came in. I have my new one now and replaced the bad one. I put it in the same bay, went into the Raid manager by going into Ctrl M after POST and then to Objects, Physical Drives, Chose the drive and "made it online", rebooted and I get a NTLDR corrupt message. I went back in and formatted the drive and tried again and I get NO OS found. So I failed it and am running on just the three drives again. Please plet me know what I'm not doing to enable this drive to be apart of my Raid 5 setup.

Cheers,
Chris

You do not place a newly installed drive to ONLINE status, but rather, undertake a rebuild. By placing the drive online, you've effectively told the array it's operational and data and parity state is consistent, which it is not as the installed drive has no data on it.

The ability to manually place a drive online is a useful feature typically used more in a disaster recovery scenario rather than just rebuilding a degraded array.

You should be doing a rebuild. By doing a rebuild operation, the data is (re)created on the newly installed drive. You can start the rebuild off from NetRAID Express (CTRL-M at POST) or better still, online using NetRAID Assistant.
