I would like to remove a working drive in a raid-1 array, replacing with a new drive, in order to hopefully build a "test system" where I can experiment with OS upgrades and migration of an old "point-of-sale" enterprise software for which we have no original installation disks. I have also been unable to upgrade drivers on current system and would like to upgrade to a current, stable CentOS that our software will run on.
Origin system is Dell PowerEdge 410 running CentOS 5.11 and raid card is Serial-Attached SCSI SAS 6/iR. "Test" system is a Dell Optiplex 360 with a Dell PERC 6i card.
Can I create a "duplicate" raid array this way if I rebuild using removed disk and bypass initialization? If so, I will also duplicate our BackupEdge set-up with a NAS device (all of this on a separate LAN and WAN, of course) so I can then "experiment away", as I fully expect to create a few Linux "pieces that I can keep" during the learning process! (newb/determined hobbyist/family store I.T. guy)
My first posted question and I appreciate any help!
PS - Next question will be regarding how, if at all poss to re-install the pieces and resolve the dependencies of our old P.O.S. program to an OS that is NOT End of Life...
