[dedicated thread] Dell Open Manage Appliance (OME)

456Q

@anik I'm trying to setup dell open manage enterprise for a couple of weeks.

I imported version 3 and 4 from esxi. Both won't work after. I also tried to convert ovf, kvm and hyper v image. The conversion worked. But open mange will not boot on xcp-ng.

I got a supported ticket open for this as well.

No luck so far.

@456Q Hi !

Can you give me the link to the open manage image (just to be sure i have the right one) ?

I have 3 R630 with enterprise iDRAC, i can try it in my infra to see i'll be able to boot it

@Danp
Thanks, at least I have something to do during my insomnia
@456Q I'll keep you posted !

AtaxyaNetwork

@456Q

It's working !

Let me write a small tutorial to explain how i make it boot, i'll post it ASAP.
Or if you prefer, I can send the .vhd with the patch directly

456Q

@AtaxyaNetwork No way That's fantastic. I'm really curious to learn the fix. It might help someone else here as well.

So please post the steps if its not to complicated.

THANKS
Stefan

@456Q I'll do a blog post since it will be a little long to explain here

TLDR: Dell remove entirely the Xen driver, which is needed to be able to use the disk and the network. Had to install an other SUSE (yeah, OME is an SLES) to get the driver and insert it in the OME VM via a rescue box

456Q

@AtaxyaNetwork Oh wow. That might be past my linux skill level. I would love to try the vhd file if you can share it with me. This should get me started for sure. But please do the blog post as well.

AtaxyaNetwork

@456Q No problem !
Let me export the .vhd and upload it somewhere. I'll give you the link in private, with the password of the appliance

I already start to write the blog post

456Q

@AtaxyaNetwork THANK YOU

AtaxyaNetwork

@456Q I sent you the link in private chat

@AtaxyaNetwork Hey! I've been trying to deploy OME within our Xen environment, but I am having issues with locating the blkfront and netfront xen drivers. The repo links in your blog post aren't working for me and the OpenSUSE driver repo doesn't contain these files any longer. Are you able to help me?

AtaxyaNetwork

@adminofadmins Hi ! DM me

@AtaxyaNetwork Thank you so much for posting this and I was able to get OME up and running however I'm running into an issue with disk space resources. I increased the disk to 800GB and ran the "Configure Appliance Disk Size" but says it didn't find any unused space., so I can't install any plugins. It's crazy how much this solution requires for resources. Any ideas how to fix this or you ran into this? I'm assuming I need to tell linux I increased the disk?

AtaxyaNetwork

@pctechsolution Yeah someone ran into the issue too, i found the solution but i didn't update my blog post. Let me check my notes

AtaxyaNetwork

@pctechsolution Found it:

I rebooted the VM with a Debian CD and searched using grep to check if "/dev/sd" was present in any files—and it was!

You'll need to modify two files (with a live CD):
    /opt/dell/omc/utilities/tui/bin/ome_disk_config.sh
    /opt/dell/mcsi/appliance/scripts/appliance_ressource.sh

In these files, replace /dev/sd with /dev/xvd.

After making those changes, reboot the VM, and you should see the 415GB appear on the "Configure Appliance Disk Size" page.

Let me know if this works!

@AtaxyaNetwork First off thank you for taking the time to answer my question and I made that change and BANG it saw the extra space in the appliance when scanning disks however now I'm met with this error. I don't remember the CPU or memory being an issue only disk space before I made the above changes. Even though I scanned and added the disk space still shows 0GB free. I also added 30GB of memory to the server but showing 0GB allocated! The first time around I only gave it 16GB and said not enough and I added more like 24GB and the memory error went away but now all those errors are persistent?

Also shows in the appliance the disk space?
