Raid- mirroring in suse 10.2 server
 

We have SUSE 10.2 SP2 installed on HP Proliant 350G5 Server with our software with 160GB SATA hotplug HDD. Now we purchased 2 HDD same and want to mirroring these HDD. We configure these and in SUSE Yast- Partion 3 HDD is showing one is OS SUSE (Linux 083 147 GB+ Swap2 GB).
We want to mirroring these HDD to existing one for secure our data. Kindly suggest the entire process how we make RAID and what type raid with command.
Thanking you.

Greetingz!

On an HP ProLiant DL350 G5 running SuSE 10.2 SP2, you call support. If this isn't for a business, and you don't have a support contract here's what you do.

1) Backup *all* your data.
2) Reboot the server, and go into the FirmWare for the onboard SmartArray controller.
3) Destroy the existing Logical LUNs & Array definitions.
4) Shutdown the server.
5) Add your drives.
6) Boot the server, go back into the FirmWare for the onboard SmartArray controller.
7) Create a new Array definition with mirroring (RAID5 or RAID10) using the disks you want
8) Create as many Logical LUNs off the Array as you need.
9) Reboot and reload the OS from your kickstart/jumpstart server.
10) Restore your data.

Any software-based mirroring will have to be done with the "mdadm" command, and you may want to implement logical volume management (LVM) on top of that. Check your man pages for details.

NOTE: Either way, you're probably going to have to backup your data, reconfigure & reload the server, and restore your data.
