Replace drive in RAID 6 array

Jump to solution

Hello,

I have a PE T610 with H700 raid controller, 2 drives in RAID-1 and 6 drives in RAID-6 array. One of the drives in the RAID-6 is showing media and other errors. The drive is still online but I have issues with it and want to replace it.

Enclosure Device ID: 32
Slot Number: 4
Drive's postion: DiskGroup: 1, Span: 0, Arm: 2
Enclosure position: 0
Device Id: 4
WWN:
Sequence Number: 2
Media Error Count: 17
Other Error Count: 145
Predictive Failure Count: 0
Last Predictive Failure Event Seq Number: 0
PD Type: SATA
Raw Size: 2.728 TB [0x15d50a3b0 Sectors]
Non Coerced Size: 2.728 TB [0x15d40a3b0 Sectors]
Coerced Size: 2.728 TB [0x15d400000 Sectors]
Firmware state: Online, Spun Up
Device Firmware Level: CC4B

The drives are HotSwap. My question is, can just unplug the drive and plug the new one or I need to use megacli to first set it offline like this:

megacli -PDOffline -PhysDrv [32:4] -a0
megacli -PDMarkMissing -PhysDrv [32:4] -a0
megacli -PDPrpRmv -PhysDrv [32:4] -a0

Thank you in advance for your help.

You should be able to simply replace the drive and rebuild automatically.  That said, before doing anything, be sure your system is fully backed up.  RAID is redundancy - NOT a substitute for having a current, functional, verified backup.

I haven't said that I don't have a backup, I just want to fix this array. Thank you for your answer.
