RAID 1
Hi,
Is there a solution the configure or choose which hard drive is the source and which one is the destination in a RAID 1 on a proLiant 360p Gen8 please ?
I want that the disk I insert copy on the disk who is already in the server but it's the inverse that happens.
Thank you for your help.

Re: RAID 1
I think this cannot be done that way.
If you insert a new disk in a running server, the system will consider this disk as unused and will use it as a spare or just available disk, no matter what is on the disk.
If you insert such disk in a powered off server and the disk was installed in another server before, it will complain about missing disks in this RAID set.
What is your goal?
Hope this helps!
Regards
Torsten.

Re: RAID 1
I have 2 servers with the same hardware profil, one is a disaster server and the other is productive. If I have a problem
(other than disk), I want to take the disk on the productive and put it in the backup server.
Any idea ?

Re: RAID 1
Thank you Torsten, but I want to move only one disk... (I have a backup disk, it's the disk I want to put in the disaster server)

Re: RAID 1
You cannot transfer a single disk of a pair because of the internal voting (roaming rules), it won't work.
But you couls insert a new disk into the productive server, create a single disk RAID0, clone the boot disk with a cloning tool of your choice and transfer this disk, this could work.
Hope this helps!
Regards
Torsten.

Re: RAID 1
I understand what you propose.
I have already 2 disk in the disaster backup. But I want to change just one (with the data of the productive server) and what I want is that the RAID 1 build it with the new inserted disk. It isn't possible ?

Re: RAID 1
Not possible because of the drive roaming rules.
Hope this helps!

Re: RAID 1
Hello Sbea,
try this and see if this fits what you want to achieve:
- production server has only 2 disks and they are in raid1
- pull out disk 1 and insert a new/unused disk to rebuild your production server (bring it back in a redundant disk status)
- insert the removed disk 1 now into the powered off backup server in the same slot (1) and boot the server
- the backup server will come up and complain that disk 2 is missing, once passed that message and when the OS is up,
insert another disk and the raid 1 will rebuild also, giving you a redundant disk pair also in the backup server.
You might get a prompt to press F1 or F2, choose the one to enable the logical drive, if not you won;t be able to boot.
Key point is to boot the backup server only with the disk 1 that was taken from the production server, no other disks
can be installed.
If the array configuration is larger and includes other raid arrays, there will be more Smartarray errors at POST.
As already mentioned, the disk that resides in a server will always be the source, there is no way to make it a target ever.
HTH
