Hi,

While using MaxView Storage Manager on Ubuntu 16.04

with Expand/Migrate Logical Drive option in web GUI menu.
whole array is lost.

Steps:
1> INITIALIZE ALL disks # arcconf task start 1 device all INITIALIZE noprompt

Controllers found: 1
Initializing Channel 0, Device 9.
Initializing Channel 0, Device 12.
Initializing Channel 0, Device 13.
Initializing Channel 0, Device 14.
4 device(s) initialized.

Command completed successfully.

2> Login to Web gui of MSM..
clink on controller --> create logical device ---> custom mode -->RAID 1 Mirroring; 2 drives required; redundant ---> select minimum two drives ---> next ---> finish.

3> Click on new logical raid1 device, click expand/migrate logical device

RAID1
Select a RAID level and click 'Next' to continue
 Select raid Level
 RAID Members
 Set Attributes
 Summary
 RAID 1 Mirroring,2 drives required, redundant
 RAID 5 Striping with parity,3 or more drives required, redundant
 Simple Volume A single drive segment,not redundant

Select RAID5, add additional drive, next, Finish,

Existing RAID 1 logical device is lost.. there is no migration <-- ALL data lost...

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)..
for 14.04.3 we tested with outbox driver
# modinfo aacraid
filename: /lib/modules/3.19.0-43-generic/weak-updates/aacraid/aacraid.ko
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

The corresponding bug for this issue has been closed as unreproducible. Unclear why that was not communicated here. This launchpad can also be closed.
