  While using MaxView Storage Manager on Ubuntu 16.04 
  from https://w3-connections.ibm.com/communities/service/html/communitystart?communityUuid=7bb2d98d-64aa-437d-863e-db67dc1f50db


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

  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

  Select a RAID level and click 'Next' to continue
  	Select raid Level
  	RAID Members
  	Set Attributes
  	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,
