Red Hat / Fedora :: Emulex Driver Error Message 'SCSI Layer Issued LUN Reset'
Feb 1, 2010
i have a linux machine installed with RedHat 4.7 x64 bit. toady our machine just hanged and the only thing we can do was to do an hard reboot.i saw that when she hanges all her disk looks offline. in /var/log/messages i only saw this error message:
we have 6 disks in RAID 5 in this machine- SAS disks. i've search in the net and looks like the emulex driver told the SCSI to do a reset for some reason. how can i check this issue? machine is online now and everything looks ok but i'm afraid i have a problem perhaps with my disks and this is a production machine so it cant happened again.
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
Feb 13 13:29:15 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 code....
In /proc/scsi/scsi, we can see the scsi host no. (scsi identifier no.). for e.g. Host: scsi4 Channel: 00 Id: 01 Lun: 00 In above e.g., scsi identifier no. is 4. Whenever we modprobe a particular module associated with scsi devices, we can see new entry in/proc/scsi/scsi with a greater identifier no. When we do rmmod on that module, the entry from /proc/scsi/scsi wipes off but still the counter of scsi identifier no. doesn't decreases. is is there any way to reset or decrement this counter so that next time when I do modprobe on scsi related module, it will assign no.s starting with 0 ? I found that during registering a scsi device, scsi_register() method gets value from "next_host" (which is a static int initialized to 0) and then increments next_host counter. Also, during scsi_unregister(), it decrements next_host counter. rmmod internally calls scsi_unregister(). So, if it is true then why the scsi host id. doesn't decrement during rmmod?
I can't find a be2net driver for the emulex nc553i nic that is being used on the HP 460c Blade G7. I tried to build one from the src rpm provided on the HP site but it fails looking for a be_xmt function.
i have this error message after configuring nvidia graphic driver. there is one line that says FAILED, i pray somebody to explain to me what it means and solution.

I have a dell PC running on Fedora 12, and I would like to install this SCSI controller card from adaptec:[URL]I see that the driver for Linux is available only as source code. Can somebody please indicate me how to proceed? I am not advanced enough in Linux to know what to do with it myself...I downloaded the most recent (v2.0.26) Source Code for Linux Kernel v2.6 on all platforms.Here are the contents of the tarball (if it helps in any way):
Hi I am running a fedora 10 desktop. when i send an email using evolution the message was not sent but returns a error message:"Error while performing operation.DATA command failedError: 550 Viagra SPAM - Hi in Subject" and the message did not have an attachment just plain words. what might have gone wrong for i have been using this for sometime without a problem. or what security measures should be in place to remove this viagra spamAm I infected by virus on this fedora, all my updates are up to date.
I installed the nvidia driver from the vendors homepage. But since it does not support regulation of brightness (and the display is that bright that I want to downlevel it), I wanted to go back to the default display driver which is the nouveau driver.So I uninstalled the nvidia driver and then I realized that I didn't make any backup of the xorg.conf file prior installing the nvidia driver. Shame on me, yeah.Now when the x-server started, it couldn't find the nvidia driver. Okay, fair as it was removed. Next to that my keyboard becomes unresponsive. That's really aching as I can not switch to a text-based console any longer.I'm able to boot into initmode 3 by editing the kernel parameters in the boatloader. I'm also able to edit the xorg.conf with vi in the shell then and start the xserver to test things by calling xinit.
I already tried to recover a bit from this situation by removing the references to the nvidia driver and replaced it with some information I could find on the nouveau homepage - but no luck so far, keyboard still freezes and login window does not appear. I could take a look into the xorg.0.log which warns me about the keyboard getting disabled but I do not really understand why. Next to that I find some other additional information. My computer experience is quite okay, but I'm somehow new to Fedora, I started half a year ago with Fedora 13 on my other laptop which worked like a breeze.
I wondered where I can find information about how to configure the xserver in the default configuration, if there is some reset functionality or so, that brings me back to installation defaults. Those worked ok for the nouveau driver. Unfourtionatly I was not able to gather the correct package name that would probably had helpded me by removing and installing it again.Next to fixing my setup, I had another idea as this is a quite new install to just re-run the install again on to that machine. Is this possible with keeping the files in my homedir?
I am trying to install a HP deskjet 1000-J110a. I downloaded a driver package thing, and I guess I unpacked it, and I made it, and I thought I installed it. I am totally confused and my brain hurts. The printing troubleshooter is telling me: Missing Printer Driver
Printer 'Deskjet-1000-J110-series' requires the 'foomatic-rip-hplip' program but it is not currently installed. I found something that is the 'foomatic-rip-hplip', but what the heck do I do with it?
im trying to send pages of 4096 bytes from kernel layer of server to kernel layer of client over a network. previously i tried the foll. code , for data less than a 100 bytes it worked fine , but for something larger than that the computer hangs......(even the dmesg's wont say why) i also wanted to know how we could use the 'sendpage' function to solve this problem.
i am writing block deriver for usb device in linux i want to read and write data to/from usb device i already registered usb device with my driver and opened the handle for the usb device now i need to send scsi command to usb device to make it work but i dont have knowledge about scsi commands and how and where to use them now i need to know which scsi command i need to pass to the usb device and how can i pass that command to usb device also i need some information like how to register host controller with my usb driver
if anyone knows about this or where can find the tutorials / documentation/ framework for the same.
I got the error: "An unrecoverable processor error has been encountered. The virtual machine will reset now." I have edited the options in installation screen with adding noreplace-paravirt at the end of boot parameters. but still have this error and FC installation does not continue.
I'm unable to reset using either the reset option in gnome shell or the command using a terminal. When I select it the shell exits and displays the graphic "exploding" and then it just sits there. Shutdown works fine; just no reset. Any ideas? I've installed from the DVD. I booted the live CD and it resets just fine so I know it's no my hardware
I tried adding two printers.. One remote. So I go into add printer, type its IP address.. comes up blank. no error message, it just waits. I type ipp://192.168.1.77 instead, still the same.. I eventually gave up and added the printer from [URL] Local printer. I plug its USB in. It hums for a while, pops a message saying cannot find driver and disappears. I try manually adding, again it just sits. localhost:631 saves the day again. What gives? The old printer management tool was much better, it actually worked.
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.
I'm a recently proud owner of a new Aspire AS3810T with Fedora 12 installed, when it boots up before entering the boot screen when it loads I see this error message:IOMMU: Mapping reserved region failedHow can i fix this error? It's quite frustrating
on an older computer. I get as far as the screen that asks if I want to try or install and then I get a message saying the screen resolution is wrong and I need to reset. I even disabled the hard drive in bios and still get this message. computer was built to run xp and had ubuntu on it before. I tried to upgrade the nvidia driver and broke it.
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
When I send mail via Evoultion it does seem to send ok but still the following error message comes up: Error while sending message. Failed to append to : Unknown error Appending to local 'Sent' folder instead. Not sure what's up with that but thought I would mention it.
If, as an example, I issue a command: sudo apt-get install build-essential libx11-dev libxi-dev and it tells me xx bytes will be used, and after that again: sudo apt-get install build-essential libx11-dev libxi-dev and again it tells me xx bytes will be used, do I get a second installed copies or does it overwrite what I did first?
Im trying to instal Sun Virtualbox but when download completes and I click on install I get the following error>>Message did not receive a reply (timeout by message bus) I wont even bother with this software if there are others out there that are as easy to use. I used it on Windows and thought it was great ! (thats how I eventually switched to Linux, by using it virtually at first)
I want to display the associated host name with each address.
I've found the /var/lib/dhcp3/dhcpd.leases file, but it appears to have an entry for every time a lease was issued so it's hard to tell which ones are currently active.
I've lost 6 CD-R's to this error. I have no idea what the hell could be wrong. I do not have a SCSI interface in this unit, but no matter, when ever I try to burn a cd it starts and then spits out this error; "SCSI error on write(16,16): [5 21 02] Invalid address" The log from the first attempt to burn that fails. Just before this I had burned a CD and the only problem was it couldn't eject it at the end.
I currently have a massive problem with my main webserver: one of the SCSI drives where I keep my htdocs seems to have failed (sd 0:0:0:0: [sda] Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK,SUGGEST_OK end_request: I/O error, dev sda, sector 7797601).
Since I have no backup (dumb!dumb!dumb!) of it, I tried to copy what I could on the fly, but that failed miserably. The next idea was to umount the volume and try remounting it R-O, but I have a bunch of apache2 processes that are apparently reading/writing on it and I can't seem to find any way of terminating them. I tried via init script, killall and kill -9 but they just don't respond. Until I can terminate those processes, I won't be able to unmount the drive and try saving what's left of the data.Oh and the cherry on top of the cake: the server is 1100 miles away so I can't even access it physically..Is there any way I didn't think of to get rid of those apache processes?
