I assume your problem is, you have only 2x HDD slots!? What is your OS again?
If you're worried about if HDD is detected on SATA controller here might be another solution for you, if you're able to get OMSA installed. 1. Install OMSA 2. Migrate your RAID1 into a RAID0 3. Remove the unused HDD + install the new one in that slot 4. Create a RAID0 on new drive 5. Do all your copy stuff as required 6. Shutdown server remove old RAID0 + old HDD 7. Install 2nd 1TB HDD 8. Boot from that drive 9. Use OMSA to transform your RAID0 into a RAID1 Jens From: [email protected] [mailto:[email protected]] On Behalf Of Fabio Catunda Sent: 20 April 2010 17:10 To: linux-poweredge-Lists Subject: Re: Hot disk change. Tino and Jens, # fdisk -l (with comments about what is what) /dev/sda1 1 243 1951866 82 Linux swap / Solaris (SWAP) /dev/sda2 * 244 729 3903795 83 Linux (/boot) /dev/sda3 730 3161 19535040 83 Linux (/) /dev/sda4 3162 30318 218138602+ 83 Linux (/var) I'm not that worried with the partition table because I can just delete the partition, create it again with the new size and use resize2fs to resize the file system. Usually I do that with virtual machines and it works, shouldn't be different with a real hardware, right!? I'm really worried to know it Linux would be able to read the old disk connected on a different SATA port. Cupertino, I got worried with your solution because I don't know is I can expand the virtual disk and things like that, I don't have much expertise with RAID controllers. And if something goes wrong (read: if I make something wrong), I will loose everything. I do have backup and everything, but I prefer a short downtime. Thanks again. Fábio Catunda.

I really cannot install everything from zero, it will take too long and might not work. I would like to know your opinion about the following procedure: 1 - Shutdown 2 - Remove both disks 3 - Plug both 2TB new disks and create a new virtual disk on the controller 4 - Plug one of the old 250GB disks in a separate SATA connector 5 - dd if=/dev/sdb of=/dev/sda (where sdb is the old disk and sda is the new virtual disk) 6 - fstab, resize2fs, etc, etc...! I really don't know if the OS will recognize and be able to read the old disk plugged in another SATA connector. Thanks in advance.
