Converting RAID 0 to RAID 1 DL380 G2
I have a boot device in ID=0 on a DL380 G2 currently configured by the Smart
5si RAID controller as RAID 0. Is it possible to insert a second identical device and reconfigure the existing RAID 0 volume to RAID 1 without losing data? -- Will |

Wait ... I can test that for you, but it will be a few days before i can post the results - LC |

Is it possible to insert a second identical device and reconfigure the existing RAID 0 volume to RAID 1 without losing data? I recon you can. Either way: - You should have a backup before you try any array manipulation - If it's possible, it will let you do it - If it's not possible, you won't have the option - Update to the latest firmware BEFORE you start So I recon you can quite safely go for it. I know RAID 1 to 5 migration works fine. (2 to 3 disks), but I've not tried any other permutations. Do it theough the OS / ACU - it won't let you do anything destructive that way. |

Converting RAID 0 to RAID 1 DL380 G2
"." wrote in message
om.au... The second method is simply to add the extra drive into your machine, reconfigure array to RAID1, and wait for it to rebuild. This should be no problem as long as you don't change the location of your original drive. Just to let everyone know, on the DL380 G2, I was able to add a second drive, then under Windows I configured it to belong to the same array as the existing RAID 0 boot device, and I migrated the logical drive to RAID 1. It worked fine. Now I have a follow on question: let's say I want to do an experiment with the DL380 G2 that involves destroying the current RAID configuration entirely and creating a new one. I power off the machine, remove the current drives, reboot and destroy the RAID configuration, then insert new drives for the experiment. When I'm done with that experiment, can I just remove the experiment drives, destroy the RAID configuration again, power off the system, and then try to boot after inserting the original drives? Will the RAID pickup the configuration on the original drives and try to re-establish it? If not, is there any way to do what I am describing here a different way? -- Will |

If not, is there any way to do what I am describing here a different way? -- Will Yes, the array setup will automatically revert to the configuration that is stored on the original (non-experimental) disks. The array configuration is stored at the controller level, and at the drive level. This is done so that if a controller failure occurrs, and the device is replaced, the drives will then "teach" the array controller about the array configuration that existed prior to its installation. Let us know if you have more questions. - LC |
