BL460G7 raid 1 breaking and data recovery
We have a task to upgrade sas hdds to ssds in bl460g7. However we have to shrink the size from 900gb sas to 800gb ssds.
We can rebuild the array with same size or bigger size drives. How can go with this operation..
Please advise.

Re: BL460G7 raid 1 breaking and data recovery
THanks. That's waht i thought to. Initially we want to know if the following work.
) We break the mirror and leave 1 disk in the server. Thus the server only has 1 disk with all the data on it. Leave that disk with no RAID configuration so that when we insert the new SSD, the server will see them as totally separate disks with nothing to do for them.
2) Then, within the OS, we could create a new Volume Group on that new disk, and copy the data from the old to the new. Now we have 1 old disk and 1 new disk with the same data on them and no mirror\RAID config.
3) Now we remove the old disk and configure the new disk to be a mirror.
4) Insert the second new disk and let the RIAD mirror the 2 new disks.
I am certain about the first step but not sure if we can copy data from unmirrored disk to the new ssd which we have to create new volume group (partition).
please advise.

Re: BL460G7 raid 1 breaking and data recovery
This guide is a bit dated, but the same principle applies today using HPE SSA instead of ACU. I'm not sure what you are attempting is possible doing the break / recombine method since the new drive is smaller than the original drive. Basically you split a RAID 1 into two RAID 0 drives, then you replace one RAID 0 drive with a new drive, create a new RAID 0, then convert to a RAID 1

but keep in mind you cannot mirror to a smaller disk, a spinning disk to ssd and sas to sata.
Thanks Torsten, I didn't even think about the rule for mixing devices in an array.
