Software :: OS Install Via Pxe - No USB Boot Option And A Broken Scsi Cdrom Drive
Aug 12, 2010
I have successfully setup a FOG server to image my Windows clients, so I have tftp, pxe and anything else related to booting to a pxe server setup and rocking. What I'm trying to do now, is use the CentOS net install files to setup CentOS on an old server with no USB boot option, and a broken scsi cdrom drive (it's a Dell PowerEdge 2400, with a single PIII 733 and 1.25GB ram).
Using the FOG Projects gparted wiki entry (adding gparted to the pxe boot menu) I was actually successfully able to pull the net install files over to the PE, and install CentOS 5.5 via local ftp server. At first it kept erroring out (I kept picking and choosing individual packages from the package groups), so I thought it may be an issue with the GUI install (the python script kept spitting back errors forcing a reboot). In any case, I finally got through the GUI install, but now I need / want to know how to force a text mode install.
[Code]....
the bolded "append" line is where I thought I could force the text mode install script, but that didn't work. The vmlinuz and initrd.img files were both pulled form the net install iso, NOT the livecd. Would that have made a difference? If not, what / where / how should I force the text mode install script?

I have installed Ubuntu server 10.10 today and I am trying to mount the scsi cdrom drive in a Dell Poweredge 2850. I can see the device in dev listed as scd0, but when i try to mount it to /media/cdrom or /mnt/cdrom I get a long list of I/O errors: Buffer I/O error on device sr0.

I downloaded and burned the Fedora-13-x86_64-dvd iso to install on my shiny new box (MSI NF980-G65 MB, AMD Phenom II x4 945 CPU, 8GB Corsair DDR3 memory, generic ATAPI DVD drive, 2 500GB SATA drives, 2 1.5TB SATA drives). I boot from the DVD and and take the default install/upgrade option on the menu. I've tried with the default boot options and with about a dozen different options, all give the the same thing.
Looking console 3, shows the following:
ERROR loader: removing ddmode.conf failed
ERROR loader: got to setupCdrom without a CD device
It can't find the CD/DVD drive that it booted from. The install on console 1 is prompting for a driver to load. Do I need to download a driver for a generic ATAPI/IDE CD/DVD drive?

I'm trying to install WoW on my Ubuntu machine and I'm having trouble right off the hop. I'm using an install DVD thru wine and it says since the Installer.exe is hidden I need to remount my drive with the unhide option on.
I'm following this guide [URL]
This is the part of the guide I'm getting stuck at
Note that on some WoW DVD's the installer executable is hidden and you need to re-mount the disc with the 'unhide' option. To do this type in a terminal:
sudo umount /dev/cdrom
sudo mount -t iso9660 -o ro,unhide /dev/cdrom /media/cdrom0/
The unmount part works just fine but when I go to remount the drive it gives me this error:
mount: mount point /media/cdrom0/ does not exist

I have been burning a few CDs. When I inserted the blank CD I was queried what to set the default action as, and I selected 'Do Nothing'. The CDRom drive now does not attempt to read or mount anything inserted into it. It shows up in Nautilus under 'Computer', but does not appear to be mounted properly otherwise.
I am using Ubuntu 10.04 desktop.

I would like to install Edubuntu 10.10 on this ancient Toshiba with Windows XP on it. The situation is a little complicated since I have no stable internet connection (I can not download Edubuntu once more). Now I realised that the DVD-Drive is broken and I can not boot from DVD to install Edubuntu. I have, however, an external USB-Drive, but there is no Boot-Option from USB (Phoenix Bios V. 1.3). So now I figured different options:
I could update my PhoenixBios to have a USB-Boot-Support. But I don't know if that's possible, so I am asking for opinions.I sucessfully installed Ubuntu 10.10 with Wubi on the Laptop, but I wasn't able to install the packages for Edubuntu. Any time I put the DVD in my external USB-Drive and tried to mount with Synaptic I got the error message: "E: Could not mount CD-Rom". So I could install Ubuntu 10.10 with the CD, the Edubuntu-packages in addition with the DVD afterwards. Is there no way to install Edubuntu directly with Wubi?

I can't boot Ubuntu powerPC 10.04 from a exterla CD/DVD drive on a PowerPC mac that has a broken internal CD/DVD drive. If I hold down the OPTION key it shows me a list of bootable drives. It shows my hard drive and a CD icon with a tux icon next to it. I click the cd icon and then click the go arrow. The screen turns black and it loads the list of bootable devices again but, the icons are all black after it reloaded the list and I can't click on any of them.

I exchanged my CDROM drive for DVD drive. The DVD is recognized in the BIOS (will boot to DVD install disc) and in CentOS 5.2 (when I list the hardware), but CentOS must still think it's a CDROM drive. When I run VLC in a terminal it kicks back these errors code...
I think this means that "hdc" is linked to a CDROM configuration somewhere, but I don't know where to find it to change it (or out it). It also appears thee is no DVD module loading. (Of course, I could be making poor guesses.)
I thought there might be something in the fstab, but it doesn't appear there is anything there (for the CDROM or DVD drive)?
Is there somewhere else I should be looking? /dev/*** ?

Upgraded one box that has 2 drives in it to 10.04 no problem.Tried doing my other box today, and it won't give me the option to format the /dev/sda drive (first drive), only gives me /dev/sdb as an option./dev/sdb is my media drive. /dev/sda is where the previous version of Ubuntu was installed and I need to be able to install to that drive.When I boot the live cd instead of installing, I see both drives under the "Places" menu, so I know ubuntu sees both drives.

i m facing same error in most of the HCL servers. the problem is that it throws error while booting and sometimes not throws error. the error is :-
Feb 13 13:17:25 fe13s kernel: Adapter 0: Bus A: The SCSI controller was reset due to SCSI BUS noise or an invalid signal. Check cables, termination, termpower, LVDS operation, etc.
Feb 13 13:17:30 fe13s kernel: Adapter 0: Bus B: The SCSI controller successfully recovered from a SCSI BUS issue. The issue may still be present on the BUS. Check cables, termination, termpower, LVDS operation, etc

In my understanding, the way /proc/scsi/scsi gets populated, /proc/paritions also gets populated in the same fashion. i.e. the description for first entry of /proc/scsi/scsi can be seen in the first entry of /proc/partitions and same for rest.
So, With this assumption, in my project, I used to relate first entry of /proc/scsi/scsi with first entry of /proc/partitions to get its total size and same for all entries.
But, I observed some differences in following scenario, where
1) The first 4 entries in /proc/scsi/scsi are SAN luns attached to my system and for which the actual device names in /dev/ are sda,sdb,sdc and sdd.
2) The last 4 entries are the internal HDDs on same system. In /dev/, their respective device names are sde,sdf,sdg & sdh.
(Output attached at end of the thread)
But in /proc/partitions, the device order is different.
You can see their respective sizes in /proc/partition output as well.
So, my question is, in this particular scenario, I can't relate the first entry of /proc/scsi/scsi with first entry of /proc/partition. i.e. scsi0:00:00:00 is not /dev/sde, because it is actually /dev/sda.
It seems that my assumption is wrong in this scenario.
Is there any way or mechanism to figure out actual device name for an entry in /proc/scsi/scsi in /dev/ directory?
How can my application should relate /proc/scsi/scsi entries with their respective device names and sizes?

I have an issue after the installation of debian 8.2 on an usb flash drive:
I had debian 8.2 and windows 8.1 running on a single SSD. Everything was fine. I wanted to install a second debian on a 32gb USB flash drive as a live system. After the installation I am not able to boot my debian (SSD) without the flash drive plugged in. I only get a grub rescue prompt. Booting windows still works. It is also possible to boot both debian systems if the USB drive is plugged in.
So it seems to me, that the debian bootloader was accidently installed to the USB flash drive and the original bootloader on the SSD does not work properly anymore. I used a netinst image from a second USB flash drive to install debian to the first USB flash drive.
Update fdisk output:
/dev/sda1 2048 2050047 2048000 1000M Windows recovery environment
/dev/sda2 2050048 2582527 532480 260M EFI System

I just installed centos 5 on a hp dl380 server and it has 2 72.8 scsi gig hard drives. The problem I am having is that only one hard drive is being recognized and it is not being recognized as a scsi. This is what I get from fdisk -l
Disk /dev/cciss/c0d0: 72.8 GB, 72833679360 bytes
255 heads, 63 sectors/track, 8854 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/cciss/c0d0p2 14 8854 71015332+ 8e Linux LVM
as you can see, the system doesn't even see the second hard drive. How do I get both hard drives to be seen and how do I get them to be recognized as scsi?

Some of our workstations have LTO's attached and they seem to drop off every now and again, the only thing which picks them up again (besides a reboot) is the famous rescan-scsi-bus script from here
The thing is that I'd like non-root users to be able to run this script, which in turn needs root to /proc/scsi/scsi

I need to read some data from a hdd that belongs to an old SCO Unix system. The SCSI card is PCI so I unplugged it from the old SCO unix box and stuck it in a new computer and booted using a Fedora 14 USB pen drive. The SCSI card was recognized and so was the hdd but it was not mounted. I then went into Applications, Disk Utility, and found the hdd. Under 'Edit Partition' the type was blank. I was tempted to set it to 'Extended' but was not sure whether that could damage the data on the disk. Does anyone know whether I would be able to read this Hdd by setting the type to 'Extended'?

I have just purchased (AT ENORMOUS EXPENSE) a used 306637-004 36 GB hard drive. It has come, by default, with no jumpers and my scsi controller recognizes it as SCSI device 0.Very inconvenient as it clashes with my existing IBM 9GB drive I am loth to play about with.Does any kind person out there know how to jumper this drive to be SCSI ID 1 or 2 (say).

I did an installation of SUSE 11.2 on a new SCSI hard drive. Keeping the old hard drive separate. I remembered there was some info on the old hard drive I wanted.
I added this to the system and mounted a partition. I then copied the data over. Then I umounted the partition rebooted the machine and removed the hard drive. However the machine will now not boot without this hard drive even though its not mounted. Not sure what the error message im given means I think it could be trying to fchk it.Do I need to do something more like remove /dev/sdd ?

I am setting up a new server and am in the midst of testing RAID. This is an Ubuntu 9.10 server. RAID1 (/dev/md1) is spread across 12 one-terabyte SCSI disks (/dev/sdi through /dev/sdt). It has four spares configured, each of which are also one-terabyte SCSI drives (/dev/sdu through /dev/sdx). I have been following the instructions on the Linux RAID Wiki ([URL]....
I have already tested the RAID successfully by using mdadm to set a drive faulty. Automatic failover to spare and reconstruction worked like a champ. I am now testing "Force fail by hardware". Specifically, I am following the advice, "Take the system down, unplug the disk, and boot it up again." Well, I did that, and the RAID fails to start. It outright refuses to start. It doesn't seem to notice that a drive is missing. Notably, all the drive letters shift up to fill in the space left by removing a drive. The test I did was to:
[code]....
Is removing a disk from the bus a reasonable test in the first place? Meaning, is this likely to happen in a production environment by other means than a human coming by and yanking out the drive? Meaning, is there a hardware failure that would replicate this event? Because, if so, then I don't know how to recover from it.

Rebooting didn't fix things.I unassigned/reassigned the drive, rebooted, still no good.Funny thing when I unassigned the drive and reboot the system.still see /dev/sdb but no partitions and fdisk -l does not display /dev/sdb.I even did "echo 1 > /sys/block/sdb/device/delete"
and the device no longer showed in /dev, but after a reboot it is back.I pulled and reseated the fibre card, same

just bought an adaptec 39160 PCI scsi controller and 34Gb drive and installed it on my computer.When i Booted it up a utility thing ran which said 'detecting array' and it found the drive and its size etc. it didn't go any further to allow my system to boot, so I rebooted and pressed CTRL + A to enter the adaptec scsi config. I changed something in there to make the disk non bootable (i Think) and rebooted the system.
It now hangs at :
'Detecting Array .....'
and does not show the drive details or the CTRL + A option to enter the utilities. So the only option I have had is to remove the adaptec controller ( and the system boots fine) the mother board is an Abit an8 ultra - probably about 4 years old and cpu is amd 64 I guess i have broken it and my remedy would be to reset the default options on the adaptec controller, but you can probably guess I have v. limited knowledge and have not used scsi before.

I am running Fedora 14 and have a problem where I am not getting any kernel uevents for the cdrom drive.
This only happens if I do an install without the X Windows (Gnome). Also if I install CentOS 5.5 without any X Windows I do get the uevents for the cd drive.
So the problem is occuring when doing a minimal install (with Base packages and a few others) on Fedora 14.
I am running in vmware workstation 7, but I have also tried to install this without vmware on a seperate pc with the same results.
One slightly strange thing is that Fedora with X Windows detects the cd drive as VMware_IDE_CDR10 and Fedora without X Windows as CDDVDW_SH-S223L (which it really is).
I am using "udevadm monitor" to watch udev events, and "udevadm info --query=property --name=/dev/cdrom" to get the cdrom details.
