Hey! I got a SATA HDD (instead of an SCSI HDD which the T5500 doesn\u2019t have the wires to support, lol)
1st things first. Install the HDD. This took over an hour! I put it in one bay. Turned on the machine and saw that it wasn\u2019t being recognized. Hmmm
I took it out and tried to put it in another bay, but it wouldn\u2019t fit there with the wiring. Bummer.
I took the HDD out and replaced it in the first bay that I tried. The BIOS still didn\u2019t read the HDD and so I poked around in the BIOS settings.
An administrator password! The seller\/previous user should have cleared that! Aghh I am gonna have to get that from the eBay seller! And so much dust on top of that!
What a bother, then I realize, they probably have no idea where to get that info, and it would be such a wild goose chase; Instead, I should just clear the password from the BIOS.
Thanks for the easy instructions Dell!

So now I begin to start step one of My following a redditor\u2019s post journey of How do I become a Linux SysAdmin.
Google search \u201ckvm hypervisor centos\u201d
I love Redditors! https:\/\/www.reddit.com\/r\/homelab\/comments\/79j0sv\/centos_as_kvm_hypervisor\/<\/a>
Another blogger https:\/\/www.marksei.com\/howto-virtualization-kvm-centos-7\/<\/a>
The official download, I am going CentOS 7 https:\/\/wiki.centos.org\/Download<\/a>
Be careful here, older versions are not supported according to the main page.
The install is 4.5G! I\u2019ll have to wait a few minutes to download and then to write it to a flash drive<\/p>\n\n\n\n

I plugged the CentOS 7 install drive in, got to the installation menu\u2026.and it doesn\u2019t see the HDD.
Google search \u201ccentos install not seeing hard drive\u201d

Looks like there is an issue with the RAID setup, potentially from settings I may have changed in the BIOS after resetting the password.

There is something on the HDD preventing the installer from recognizing it.
I will install using the live version so that I can load the OS and reconfigure the HDD. Likely there is something on it, since I bought it used. Could be that an unused filesystem is on there and the BIOS recognizes the drive, but the OS is not able to. :-\/ Will have to wait a while longer since I thought I could save time downloading a flashing a smaller install.<\/p>\n\n\n\n

Downloaded the everything iso, flashed it, but it was \u201ceverything\u201d as in all the different standard software package add-ons, not the same as a live disk.
Refresh the live disk. Tinker around open up the GUI. See the same message when I install from live.
Then I open the terminal and tinker. Finally I Google \u201chow to see the partition in linux\u201d like a noob
I see # lsblk and realize that is the one! I have used that one before. I see it in the terminal! There are partitions on this disk!
So how to delete them.. I look to see if parted or parted is on this live disk. NO, but Gnome disks is there.
Ok, and there, I see the HDD, delete the partitions and now I can finally see the HDD to install the OS!!!!!<\/p>\n\n\n\n

OS installed. Root password and admin user created. I checked the Disk and the memory to confirm that I can see 1Tb of disk and 32G of RAM.
Now I just need to make sure that I can ssh into this box and I can move it to a more suitable place in my room.
First google result

This looks promising!<\/p>\n\n\n\n

After more than two weeks, I finally ended up posting this. Clearly still not an old hand, but this project has me feeling that IU can figure stuff out. Look up trouble with things that I already know and make it work.<\/p>\n","protected":false},"excerpt":{"rendered":"
