Problem migrating a MegaRAID from RAID 5 to 6 via WebBIOS
This server is currently running 4x 1TB SAS drives on an LSI 9261-8i in a RAID 5 configuration and used for ESXi 5.1. I have added 2 new drives which are now listed as 'Unconfigured Good'. I want to use one of those drives to migrate the array from RAID5 to RAID6. After the migration is complete, I intend to grow the array with the other disk. However, when using WebBIOS, the option to do the migration is not appearing. I've made an imgur album showing the steps I took here:
Can someone explain to me what is going wrong?
Additionally, I want to confirm that once I have begun the migration in WebBIOS, that I can then exit WebBIOS to boot into ESXi for using the system normally (although with significantly worse performance, of course). The WebBIOS documentation states 'You must wait until the reconstruction is completed before you perform any other tasks in the WebBIOS configuration utility.' which concerns me.
Edit: LSI Support pointed me to an article explaining why I cannot perform a resize (and presumably a migration): http://mycusthelp.info/LSI/_cs/AnswerDetail.aspx?&inc=8439
The relevant information there is: Please keep in mind, there should only be '1 virtual drive' on the array. If you have more than 1 virtual drive, then you cannot enlarge your array. You will have to create a backup, delete the array, create a new RAID and restore your backup to the new virtual drive.
I had thought it odd that migration/resizing were options at the Virtual Drive level instead of the array level, since the entire array would be migrated/resized.
