View 2 RepliesI want to run ISCSI target on CentOS. Both "scsi-target-utils" and "iscsi-target" can be used.
They seem to have the same function.
Is there any significant difference between them, on performance or stability?
iSCSI Server, can I change the default port 3260 to other port ?

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 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?
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.

Originally Windows Xp, my cousin changed it to Linux.
Right now I am so frustrated with this, as I have no knowledge of Linux whatsoever.
I tried looking for the Acer recovery program, but I can't find it.
I do have to say that Linux is really fast, but I like personalizing my walllpaper where I can do it with Windows Xp..
So my question is, how can I restore this computer to how it was before my cousin tweaked it?
Here is what the desktop looks like right now:

View 1 Replies View RelatedI bought a used Acer Aspire one with Linux on it and it works great. I want to restore it to factory settings but I do not have a restore disk. (not to mention that the unit doesn't have a CD drive anyways.)
I have read on other sites that Alt-F10 works but I think that is only for WIN because I can not get that to work. Is there an equivalent function with Linux.
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?
View 1 Replies View RelatedI 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?
View 1 Replies View RelatedI am attaching a LTO-3 tape drivce into my RHEL5 linux machine. Every time i used to restart my machine to detect the tape drive is there any way to rescan the buses to detect the newly attached scsi devices. In solaris "devfsadm" and "iostat" is there. I need the same kind of thing in linux.

The problem is that i have no physical SCSI devices to connect to my LAN
Therefore I have to create a Virtual SCSI device on my host laptop and configure it as an iSCSI server (iSCSI target) and share this virtual disk on the LAN.
There are two sets of repos for 4. One is stable and the other is Factory. On the repos page it says this about kde 4.4 Factory: "These repositories feature the KDE packages under development for the upcoming openSUSE release and includes openSUSE specific patches". For reasons that are somewhat involved and that I won't go into right here I am stuck in openSUSE 11.0 and can't upgrade until I get a new machine which will be some time. Is Factory unfinished and will Kde 4.4 Factory work well in 11.0?

I have one scsi storage array, JetStor SATA 416S,split into 2 halves. each is RAID5 12TB. Is it possible to dedicate each half to a different rhel5 server. I have "lsi22320-r" ultra230 dual channel scsi adapter in each server.
The first server sees the 2 halfs however the second server doesn't on the first server:
I am testing PCLinux 2009.1 prior to installing. My desktop currently runs on ME and has been out of use for some time. It still works however and I can still get online. I'm currently using a laptop running XP. I would like to make use of my old desktop and tried to test PCLinux 2009.1 today. I followed the instructions obtained online and booted from the Linux cd. The pc booted up ok and displayed the first screen allowing me to select the "Live CD" option. After enter my system hung up at "Probing SCSI Devices:Segmentation fault".

There is no CD drive on the netbook so I have been trying to install 7 with a flash drive. The netbook did not have a disk but I did get a serial number for 7 and I have an ISO of 7. I put it on my flash drive and tried to boot it, but when I click on unetboot menu "default" it just starts the 10 second timer over and doesnt load.
I used a live usb of ubuntu to go to gparted to delete the partitions so I could load up the usb with 7 on it, but again it does not work. It gives me a grub error if I try to boot up. I know there I deleted the partitions, but maybe something is still there?
In short: I need ubuntu off and windows 7 back on using only a flash drive, a serial for 7 and an ISO image.
I dont know if this matters but its a Toshiba Satellite T-115D.
I am on 10.4 with a Dell Notebook (E6400). I use it mostly with a USB mouse. Everything worked fine for about 2 months. Then I shutdown, unplugged the mouse, restarted without the mouse, and my trackpad is broken. It works a little, but text fields and some apps capture the mouse events and won't let go. For instance, the cursor gets stuck in a text field and there is no way (keyboard or mouse) to get out.
I've tried several times to fix this and I cannot. If I boot from a LiveCD then everything works fine. My theory is that the mouse configuration files somehow got corrupted in my plugging/unplugging of the external mouse. How can I reset the mouse to factory defaults? Are there a set of files I can copy over from the live CD?I tried to delete and recreate my xorg.conf file and this did not work either.
Well, my desktop's win7 installation stopped working over a year ago...so it just sat there gathering dust until the other night, when I was trying out ubuntu on it from a disk. So, well, the factory settings was vista, so i was wondering if there was something i could put into Terminal to restore it?
View 3 Replies View RelatedI have synology nas box DS710+ that has intel atom processor inside. i've installed ubuntu under virtual box, downloaded needed toolchain for x86 processors, and decided to cross-compile openvpn.
I 've started from compiling lzo library, but first question that appeared in my head - how i have to move all compiled binaries to my synology?
1. configure - okay
2. make - okay
3. make install - this is not necessary?
Will --prefix parameter helps me? or do i have to use chroot? cause there is a plenty amount of files that i need to move to my synology.
I'm using the command below to sync two directories. Problem is insted of deleting the files on the target directory it simply appends a ~ character at the end of the file name. Not sure why this is happening?I'd like to have all deletes on the source replicated on target.
View 2 Replies View Relatedit is not clear to me, by reading different postings/documentations for ntfsclone, what restrictions and/or requirements exist for the target partition (TARGET). Can the TARGET be bigger in size than the SOURCE, or must it be identical? Must the TARGET be formatted as an NTFS filesystem, or must it left unformatted?

I need to use xdelta tool in my shell script for creating and patching diff files. My PC Linux environment (Ubuntu) has a package installer, and when I try typing xdelta on my commandline, it prompted to try "sudo apt-get install".. after which it directly accessed the packages from the Internet and installed it. So I am able to use xdelta from the command-line in my Ubuntu environment.
I need to also use xdelta on my target. I am using a NFS. The bootloader and kernel are on the target and the RFS is referred from the PC. How can I install the xdelta package on my target so that it recognises the command xdelta. On Ubuntu, "sudo apt-get install", fetched the below packages:[URL]..

I have a software program which access 4 different servers running the software but with different configs. In xp I can copy links and modify as above to correctly force the program to the various servers.
I have read the various how tos on hard vs sym links which I get. Playing around with hardlinks and sysmlinks (the examples I find) does not seem to be what I need. Feel like this is pretty basic stuff but I am a bit stumped.
