Ibm Megaraid Storage Manager Full Init On

Ive got the 15.03.01.00 MSM installed.

Right now I have a 6x6TB RAID-6 array.

Based on my Googling I should be able to right click on the virtual drive in the Logical tab and pick Advanced Operations and then Reconstruction Wizard.

Theres just one problem, there is no Advanced Operations option.

I intentionally want to try it to see how long it takes, how it works, etc.

The PDF manual says: storcli cxvx start migrate option disk has this input example: storcli c0v3 start migrate typer5 optionadd diske5:s2,e5:s3 My problem is all of my drives have the same enclosure and slot number, so thats presumably insufficient (havent tried it).

I know e is the enclosure ID, and s is the slot, but I dont know what s-x or s-x,y denote or how I can use them to identify the two drives I want to add.

You have to right click on the Drive Group two levels up, not the virtual drive.

It gave me an estimate of 5 Days 2 Hours 50 Minutes for the operation.

Im attempting to benchmark the drive speed during the rebuild, but I can already tell its SUPER slow.

If it takes 5 days and you effectively cant use the array while its reconstructing, IMHO theres not much benefit to OCE.

I guess the main benefit would be if you cant copy data quickly from your backup.

In way less than 5 days I can do a full init on a new array (12 hours with these 6TB drives) and copy all the data from a backup server over 10GbE.

BIOS and leave it there) is significantly faster compared to true OCE from within Windows.

Perhaps the firmware knows that it has an exclusive lock in BIOS mode and goes faster Anyway, as of the latest 1883s, I tried an online (background) init in Windows, estimated at days.

FWIW, rebooting and going into the OPROM didnt make it go any faster IMHO, OCE is mostly a gimmick, but for someone who can only have a partial (critical) backup, it exists.

Unlikely for us home folks, but some may have full backups off-site or in cold storage.

If the plan was to upgrade slowly, say a new HDD a month, my preference would be to max out a RAID-6 to whatever number of disks youre comfortable with and then do in-place rebuilds with each new drive.
