I had a drive fail in one of my vdevs setting the state of the zpool to degraded: root@mediaserver:~# zpool status pool: zfsraid state: DEGRADED
So I started taking steps to replace the drive.
This is the id of the old disk: wwn-0x5000cca225f459d5 This is the id of the replacement disk: wwn-0x5000c5006e38bc61
1) offline old disk:
zpool offline zfsraid wwn-0x5000cca225f459d5
2) Physically replace old disk with new disk
3) Issue replace command:
zpool replace -o ashift=12 zfsraid wwn-0x5000cca225f459d5 wwn-0x5000c5006e38bc61
The replace command fails with:
root@mediaserver:~# zpool replace -o ashift=12 zfsraid wwn-0x5000cca225f459d5 wwn-0x5000c5006e38bc61
**invalid vdev specification
use '-f' to override the following errors:
/dev/disk/by-id/wwn-0x5000c5006e38bc61 does not contain an EFI label but it may contain partition
information in the MBR.**
I can't seem to find any information to help. A few forums said to use the -f option, but that seems sketchy. There are no partitions listed on the new drive
root@mediaserver:~# fdisk -l /dev/disk/by-id/wwn-0x5000c5006e38bc61

Do I have to run some command to wipe the new drive?
These are the last few lines in dmesg relating to the drive:
