Server :: Error SCSI Controller Was Reset Due To SCSI BUS Noise Or An Invalid Signal?
Feb 15, 2010
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

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 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:
kernel: lpfc 0000:10:00.0: 0:0713 SCSI layer issued LUN reset (0, 4) Data: x0 x0 x0
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.

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

Does Debian have any particular tools or nuances for installing new hardware? I saw some stuff on Ubuntu which is related... but you know.
The dmesg file shows that it's being recognized, but I don't think it's actually being used (i.e. there is no driver installed). This is what's in the dmesg file:
Code:
[ 1.384634] Block layer SCSI generic (bsg) driver version 0.4 loaded (major 253)
[ 1.855496] SCSI subsystem initialized
[ 5.146598] scsi0 : ioc0: LSI53C1020A A1, FwRev=01032700h, Ports=1, MaxQ=255, IRQ=16
[Code]....
Unless someone has already compiled a driver for Debian Lenny for this hardware, I'm going to have to compile my own I guess. The driver package seems to come with something called mptlinux-4.00.43.00-src.tar.gz which I'm guessing can be compiled for any Linux, but looking at the instructions, it's pretty much beyond me how to get started. It talks about using kernel source to build a module and such and such.

I have a Dell PE 600 box with 2 Adaptec 2110s U160 Single Channel RAID controller supported 6 HDDs.I am trying to install Ubuntu from a mini ISO - tried server / desktop / alternate as well. And also different Ubuntu versions.The mini installer runs upto setting the time zone (after configuring for DHCP et.al.) and then on the screen 'Detecting Disks and Other Hardware' hangs up.Now I am assuming its because of the fact that I have 2 of the above controllers - as I have another similar box with only 1 of the controllers and it installs/boots fine with no problems.Look forward to you suggestions/help and if there is any other info I can provide. I plan to set up Ubuntu 10.10 server on it. Btw I don't think its a Linux problem as SUSE 11.3 installs fine on the box.

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):

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 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?

Need help on how the scsi and multipathing works in Linux. From the docs i have read, i understand that by the use of multipathing we can assign multiple paths to a SAN partition. If there is a problem then one path will failover to other path.However, i am not clear on how linux recognizes the SAN partitions using the multipath drivers. For e.g. I have a HP Proliant server on which we have the following mounts:
Filesystem Size Used Avail Use% Mounted on
/dev/cciss/c0d0p3 59G 11G 46G 20% /
/dev/cciss/c0d0p1 494M 27M 443M 6% /boot

I created a new disk on our scsi san. I then ran the following command: echo "- - -" > /sys/class/scsi_host/host1/scan. did that command for each host. and in dmesg, it shows it found a device /dev/sdg. but when i do a fdisk -l. It never lists /dev/sdg. I just did this other day on another server and it worked fine like that. This is RH 4.8.

I am looking for a way to partition 2 disks automatically with are both connected to 2 different scsi controllers.
I want one disk on one controller to be partitioned with boot and lvm and the other one with a different partition layout.
I there a way in kickstart to do this, like for instance specify the drive module?

Client has a server running 5.5 (I think) and it they moved locations. This server is used in other locations (state) via ssh tunnel as well so they can all access files.
When attempting to boot up I get screenshot 1 (superblock errors)[url]
They supposedly have a backup on a hot swap scsi and I want to know how/if I can restore it using that backup if I cant fix the superblock boot/error issue.
I took some other screenshots:

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

I am trying to install Ubuntu ver.10.10 server on HP DL360 with 2 internal 36GB untra3 scsi drives. The installations seems to have gone fine but upon booting, the OS is stoping at the BusyBox menu with initramfs prompt. None of my boot or root filesystems is mounted here so I can not go further. I've searched all over the net for answers but nothing seems to work.

I 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?

I have installed an old HP Scanner on my Fedora 11 system, and it works great. The scanner is connected through a SCSI, and it gets recognized at boot time if the scanner is ON. However, if the scanner is OFF, I need to turn ON the scanner and reboot the workstation for the SCSI devise to be recognized. Is there a way that I can rescan the SCSI devise without rebooting?

I'm trying to install the Xubuntu 10.04 i386 Alternative build on a Pentium 2 Compaq PC with a SCSI hard drive. I run the installer but when loading it chokes up trying to read/write the SCSI harddrive and fails to install.
Do I need SCSI drivers or are they included and my disk corrupted? Windoze 98 and NT4 work fine on this PC.
