Hi Noah,
There is no out box driver built for Ubuntu 16.04 yet..
Also we were asked to test inbox Ubuntu 16.04 driver.
Hence except the driver reset everything is outbox.
Yes, this issue is RAID 1 to RAID 5 Migration failure.. not only failure, the existing RAID1 gets deleted by this action, which should not have happened at any cause.
With regards,
Naveed

Once mirrored to Launchpad, please open to PMC-Sierra / Microsemi.

Hi Dough,
We tested this today on 14.04.3 and RAID migration fails here as well (RAID1 drive was deleted when we tried to migrate to RAID 5 by adding another disk).. 3.19.0- 43-generic/ weak-updates/ aacraid/ aacraid. ko
for 14.04.3 we tested with outbox driver
# modinfo aacraid
filename: /lib/modules/
version: 1.2-1.41059
Hence this issue was present in 14.04.3 as well.
let me know if any logs with respect to 14.04.3 is needed..
Also any updates from JIRA re-open?
With regards,
Naveed
