I had a drive fail on my server. I replaced it. During the rebuild it failed with a ECC error. So I have 1 drive failed and 1 drive with ECC errors. What do I do?

p0 is degraded and not failed.
therefore you should replace p1 and rebuild the raid

good luck

p0 failed, I already replaced it and started the rebuild. p1 is the "working drive."

This is how i fixed it. p0 was a new drive i could not finish the rebuild with it because of ECC errors on the "good drive"

# clears the ecc errors.
# ./tw_cli /c0 rescan

Issue the command to start rebuilding the array onto the new disk in port0: NOTE THE ignore ECC command.
# ./tw_cli /c0/u0 start rebuild disk=p0 ignoreECC

If you need to, pause and resume the rebuild:
# ./tw_cli /c0/u0 pause rebuild
# ./tw_cli /c0/u0 resume rebuild

Check the rebuild progress and RAID health:
# ./tw_cli /c0 show
