Upgrading storage on HP DL360 G5 Raid 5
Posted on 2013-01-28
I'm trying to upgrade the storage in a HP DL360 G5. It currently is running 4 physical SAS drives at 73GB running in RAID 5 using a P400i Raid controller. We have bought 4 300GB SAS drives to eventually replace all drives.
From my knowledge of RAID 5, if you replace one drive with an existing drive the data from the current drives will replicate across the replacement drive. However I have tried this and I'm getting an error.
I powered down the server and replaced one SAS drive, however when I boot the server I get the following error:
Slot 0 HP Smart Array P400I Controller (256MB, v7.18) 0 Logical Drives
1785-Slot 0 Drive Array Not Configured
Drive positions appear to have been changed.
Run Array Diagnostics Utility (ADU) if previous positions are unknown.
Then turn system power OFF and move drives to their original positions.
**** Boot Logical Drive is configured but is Missing or Offline.
I can boot into the array configuration utility, it detects the drive, however there is not an option to rebuild the existing array.
I removed the drive and left 3 drives in and booted the server to put the server in recovery mode, however putting the new drive in causes the same error.
I have been researching the issue and have come across the suggestion to Hot Swap the drives whilst in the operating system, however I thought it would be safer to do this whilst the server is off preventing the risk losing any data.
Any help would be greatly appreciated
