Perc H700 storage unavailable

[Butterfinger]

Greetings,

First time user taking a stab at Proxmox. I previously had ESXi installed and after hearing some good things about Proxmox, I installed it over ESXi.
My server has two raids: one for a NAS solution; the other will run my VMs. To clarify, the raids were built by the H700 card and were visible within ESXi.
I also have a standalone drive where Proxmox is installed.
After installing Proxmox on a separate OS drive (the same one used for ESXi), neither raid is visible. I went to Storage and tried to add them but nothing was found. And after I applied all available updates, I can't even seem to add storage devices now.
My search on here didn't provide much other than I may need to update the firmware but that only came from a post that was a couple years ago. If anyone has some insight, it would be appreciated.

Probably better off disabling the RAID hardware, and using the ZFS RAID in the Proxmox installer. You will need to read up and plan that.

Some advantages are outlined in this Wiki page https://pve.proxmox.com/wiki/Storage:_ZFS

how did you check the availability of your raid volumes exactly?

please note, you need to configure your additional raidvolumes via CLI before you can use/see them on the GUI.

 

[RobFantini]

did you add the raid array as a file system from cli?

or are you trying to use the drives as zfs ?

PS: raid cards for zfs - especially perc h7* - do not work well. we tried using those cards with each drive set up as raid 0 [ as suggested from searches ]. when a drive failed we lost the zfs pool. for dell we install LSI sas9211-8i IT firmware

 

[Butterfinger]

Looks like I need to take another look at the docs for adding an array.
No, I did not add them from CLI. So I'll start looking for docs discussing that.
I hear a lot about zfs and wanted to try it out but after's Rob's experience, I may just play it safe and use another filesystem.

 

[Butterfinger]

So I tried to disable the hardware raid but the installer didn't see the drives at all. Maybe because the card doesn't support JBOD mode?
I've looked around to see how I can import my two hardware raid configurations but I haven't found any documentation on that. If someone can post a link, that would be appreciated.

for zfs don't use the H700 . It is perfectly use for dell raid - then just format the drive ext4 in linux. then the directory can be used as storage in pve.

as far as importing the raid - i think the 'lifecycle' dell utility at startup is where to do that. I've used that and dell on line documentation.

Ok. I'm good with using H700 card and not using zfs. That's for another time.
I've now decided to install Proxmox on one of the raids since my standalone drive cannot be included in either RAID. And I don't like having a single point of failure for the OS.
So, I'm confused why I would use a dell utility to have Proxmox see my second RAID. Sorry, I'm just not seeing the correlation.

pretty sure he is referring to the "menu" that some Raid-controllers throw onto your monitor during boot-process.

setup your raid there.
Then in proxmox format that "fake-drive"/"Raid-Array" to ext4 and add it to your GUI in Proxmox (see wiki)

arrrrrrrrrrrrrrgh!
Built the raids from the Perc's menu and I saw both of them within the Proxmox installation. When I picked one, I got errors:

 

[RobFantini]

try leaving attached just the drives you want to install to. after install reboot . make sure that works, then restart and insert the other drives.

if an issue check bios boot order.

dell perc raid is not fake !

 

[sigxcpu]

He said "drive".

 

[RobFantini]

I thought by "fake-drive"/"Raid-Array" you meant that the prec raid was fake... I sit corrected.
