We are trying to install a CentOS-based Openfiler distribution on Dell R630 server with PERC H330 mini RAID controller but unfortunately, the installation can't find a hard disk to install the OS.
Any ideas on how to solve that?
The Linux distribution doesn't contain the necessary driver packages. It might be possible to create an an device driver media, like an USB stick, which does contain the RPM installation packages. More information you will find in the Driver Installation section of the handbook.

Python and RPi n00b here. Trying to get CANopen working on my RPI, and think I'm 8/10s of the way to communicating.
Target device is an RPi 3+ with fairly pedestrian install of Raspbian Buster and 5.4.51-v7+ linux kernel, attached to Kvaser Leaf USB CANopen adapter. CANopen adapter hardware is known to be good, works well with Windows software.
Relevant info:
-Installed can-utils
-Installed python-can 4.0.0
-Appear to have installed Kvaser drivers successfully (finally got make to complete without errors)
-vcan appears to work fine - have successfully transmitted and received test packets with this handy virtual can adapter using can-utils
I can set up the can socket initially:
sudo modprobe can
but when I try to initialize actual hardware, it fails and gets the following error:
sudo ip link add dev can0 type can
RTNETLINK answers:Operation not supported
Obviously I'm missing something, but cannot figure out what. I notice that others have had similar issues (though different hardware). Please advise of solutions and TIA.
You'll need to uninstall CANlib and then reboot for socketcan to work.
Follow this procedure:
Download the linuxcan tarball again if you no longer have it: http://www.kvaser.com/downloads
Extract linuxcan: tar -xf linuxcan.tar.gz
Inside of the linuxcan directory, run make to build everything which is required before you can uninstall
Now uninstall CANlib with sudo make uninstall
You should see something like the following:
Uninstalling pciefd
Remove SocketCAN Kvaser PCI driver from blacklist.
Uninstalling pcican2
Remove SocketCAN Kvaser PCI driver from blacklist.
Uninstalling pcican
Remove SocketCAN Kvaser PCI driver from blacklist.
Uninstalling virtualcan
Uninstalling usbcanII
Remove SocketCAN Kvaser USB driver from blacklist.
Uninstalling mhydra
Uninstalling leaf
Remove SocketCAN Kvaser USB driver from blacklist.
Uninstalling common
Now you can reboot and the ip link commands should work.
You need to uninstall "Kvaser Linux Drivers and SDK" and install "Kvaser SocketCAN device driver".
I'm considering getting a collection of Dell PowerEdge servers. Dell documentation is pretty poor (no surprise there) and I have trouble figuring out if I can go with iDRAC Basic or if I need iDRAC Express or Enterprise.
My need is to install Ubuntu Server (minimal install with SSH is enough). After install all I need is SSH and possibly a remote "reset" button. I can install the OS before taking the system to server room so I don't really need remote OS deployment tools. However, the server does not have a graphics adapter. Is it possible to install Ubuntu with just iDRAC Basic or do I need additional hardware?
#iwork4dell Remote OS deployment implies Virtual Console (like VNC) and Virtual Media (using a remote ISO like a local DVD). These are Enterprise license features. OS deployment tools are are the driver pack that is stored in flash on the server and made available during OS installation to support new hardware on older OSes.
The iDRAC is an integrated VGA adapter so all the Power Edge servers do have a video adapter in them unless you disable it in BIOS. If your willing to attach a keyboard and monitor to the server basic is all you need. You can also upgrade the iDRAC with a license key after purchase.
See http://en.community.dell.com/techcenter/extras/m/white_papers/20440743
and http://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/idrac-spec-sheet.pdf
IDRAC is possible, just you can open gui of idrac and then launch on the online server. You can add the iso file on virtual server.
I have mistakenly formatted windows xp partition of my hardrive while trying to install lubuntu operating system.
Now I can only have access to my computer through the live USB disk of lubuntu.
I have couple of .iso files of windows xp cd.
But when I tried to create bootable USB drive from it, it doesn't work.
It either shows "bootmgr is missing" message or it show a blinking cursor and nothing happens while booting.
The iso's that I have, contain all the necessary installation files required.
Is there a way to make USB drive boot from it?
I tried softwares like rufus but that too doesn't work with iso that I have.
try to google a software called ultraiso, it can create an installation usb using an installation Windows cd or iso, no matter the Windows is xp or 7 or 8 or Windows Server.
If you can't find it in google, try to find it using another search engine such as www.baidu.com
then using the usb, you can install Windows again in your hard drive
I've filled up my Intel Edison 100% and have no room for anything more. I've emptied all logs and am still at 100%. I decided I want to factory reset and reorganize next time with the SD card better. Unfortunately I cannot find out how to reinstall completely the OS.
I've tried downloding the Yocto linux image off the intel downloads page, and uploading that to the Edison. However, it still is running the same as before...
For some reason I distinctly remember (pretty sure anyway...) reading a command to 'reset' everything. I just can't find any documentation now that I need it. Does anyone know how to do this?
Found the command, it's reboot ota
This is my checklist
Install dfu-util (on Linux: sudo apt-get install dfu-util)
Download Release 3.0 Yocto* complete image and unzip it
Connect the module using both USB connectors.
Run sudo ./flashall.sh --recovery
Wait for the script to finish and then a few extra minutes for the module to boot.
I've found one USB hub that didn't work, I had to connect directly to the USB port on the computer.
I'm not sure if you need both usb connectors but at least the one for main power is needed.
flashall.sh is found in the unzipped directory.
i am basically asking this to minimise my OS disk space
It depends on what OS. For example, Windows installs a bunch of drivers in the hard-drive, GNU/Linux, depends on the distribuition. Some distribs, you can chose what drivers to install, besides the generic drivers.
