https://community.solidigm.com/t5/solid-state-drives-nand/multiple-failure-dc-s3500-in-zfs-raid/m-p/7382#M99 <P>I have 4 Intel DC S3500 300GB SSD's running on a Dell Poweredge 2950 with a Perc 6. Hardware RAID is disabled. They are configured in a RAIDZ. I was documenting drive replacement procedures. I removed one of the drives, did a low level format, plugged the drive back in to the hot-swap bay and dropped to NMC. I then issues the setup volume command, selected the pool, and selected replace-lun. It then exited. I did a zpool status and saw it was resilvering. Then after about 30 seconds another zpool status showed that there were insufficient replicas on the original disk called c0t4d0/old and next to the new disk c0t4d0 it said too many errors. I then went into show lun and while the other three intels all displayed the correct model numbers, the drive I had replaced said Unknown in the description. I removed the drive, plugged it into another PC, ran intel SSD toolbox, and it only sees 8 MB.
