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).
View 1 RepliesA friend wants to dump his Windows XP system so that I can install Ubuntu 10.04. His PC has a PATA CD R/W drive and a PATA DVD R/W drive on the only single channel. It has a SATA HDD. The PC BIOS will not allow me to change the order of drives to boot from, only shows the CD R/W drive first then the SATA HDD and will only boot from the HDD. I tried getting the PC to boot from the CD or DVD drive so that I could install Ubuntu from a live Ubuntu CD by disconnecting the power to the HDD, This did not work.
With a live Ubuntu flash drive connected the BIOS does not allow me to change the boot order to boot from the flash drive. I was able to boot from a live Ubuntu flash drive by disconnecting the HDD power. I then quickly hot plugged the power to the HDD so that the Ubuntu installation process could use it. But the installation of Ubuntu did not proceed, probably because it was too late to have the HDD recognised. I suspect that the jumper settings on the CD and DVD drive are such that they are unbootable.
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.

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?
When I enter "cat /proc/scsi/scsi" I'm returned with "cat: /proc/scsi/scsi: No such file or directory". I've tried this on two different installs on two different machines.

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'?
View 5 Replies View RelatedI 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.
I am running fedora 8 on a Dell 2950 with a qlogic fibre channel card.is attached to a Dell/clarion AX100.I had a drive assigned to this server which had been working for approximately a year now.Recently during a power failure things turned ugly. 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 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?
After connecting, dmesg shows:

After that, there are no /dev/sd* entries. the hard drive works as expected on my windows box. how can i mount this drive?

View 5 Replies View RelatedBasically I got Windows 7 installed on my laptop and it's been doing nothing but slowing down more and more even though it isn't used for much more than basic internet use and I realized the hard drive was the cause, I did a bunch of stuff to try to fix it that I won't get into here, and in basic I'm to the point I'm just going to reinstall Windows 7, but this time with the help of Ubuntu's partitioning utilities.
I've already had the first ~5GB of the drive overwritten with zero's (thanks to DBAN) and now I'm booted on the Ubuntu LiveCD and trying to learn the command line stuff for formatting a drive. What I want to achieve is use the smallest amount of space possible for the MBR and that's also a point I don't quite understand.
After some research on Google I read that the MBR is on one sector only the very first one, yet the first partition on a hard drive starts anywhere from 63 to 4096. Why are they so far apart? And can I force the partition to be moved closer? I know I know their is pretty much no purpose to this but it bugs me knowing that their might be 31MB (64 512byte sectors minus 1 (MBR) and 64 (beginning of partition)) just going to waste when I could put the NTFS MFT there. Then the second and last part I want to understand is I want to make the NTFS partition have a 512byte allocation unit size and have it lined with the 512sectors on the hard drive so it can have the max performance. Does anyone know how to do this stuff or could find better info than I have on the internet?
I know it is possible to boot Ubuntu Live from a Flash drive. But it just boots up and runs like its a CD. When you shut down the computer, the changes are all lost.
Is there any way to use the flash drive as a Hard Drive? like install Ubuntu on the flash drive and have the flash drive act as a hard drive - so that if I boot with the flash drive in the computer I can boot of of the flash drive and it would act as a hard drive?
Could I just setup Ubuntu and select the flash drive as the install directory? would that accomplish this?

View 5 Replies View RelatedI have a Linux system running on an older Sun V20z. The drives are mirrored in a software RAID1. The motherboard has interfaces for only IDE and SCSI. The system is old and is no longer able to handle the load we're putting on it. I also have a much newer Sun X4100. This system is presently unused and has a pair of SAS drives in it. The new server only has SAS and SATA connections on the motherboard, though. I'm trying to think of the best way to clone the V20z over the X4100. I don't mind breaking the mirror knowing I can re-establish it later. I prefer not to do a fresh OS install followed by a tape restore. I would much rather break the mirror and clone one of the SCSI drives the SAS drive. I do have a USB to SATA adaptor for migrating external drives. Anyone know if this will work with a SAS drive? Any pointers on the best way to migrate this? I'm thinking even if the cloning is successful, I'm going to have to much with GRUB to get it to boot from the SAS drive?
View 1 Replies View Relatedi have a computer with 3 users on it, and a folder using samba that everyone on the network has access to. Lets say that, the folder is stored in /etc/sharedfolder. What happens is, when user1 puts a folder in it, then logs off, user 2 attempts to modify it and fails, because permission is set to 755, and they are not in the same group. (even if they were, it should still need to be 775) Anyway, my current solution is, every 5 minutes a crontab changes permission like so: chmod 777 -R /etc/sharedfiles && chown useradmin:superadmin -R /etc/sharedfiles Which works, but seeing as there is getting close to a gig in there, this is a bad solution, as it eats up the computers resources. Solutions that i think might work:
1) create a script that only changes permissions that need be changed.
2) change file permission settings to force all documents to inherit parent document settings
Is there a way I can save system settings and have yast revert to a config file in case I ever need to reinstall the system again? I hate having to configure the firewall, runlevels, samba shares, samba workgroup, apparmor, and all the other junk after every install. It's not like I install often, but should suse 11.5 or 12 roll out, I'd like it to be a snappy upgrade.
