I've managed to install Centos 5.3 (with Gnome) from a temporary IDE-based CD drive. This has now been removed and, instead, I have added a SCSI-based Panasonic LF-D201 DVD-RAM drive onto channel-B of the Intel SRCU32 (LSI clone) SCSI RAID card.
it seems that Centos cannot see the DVD-RAM drive at all - not even as a simple CD drive.
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.

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

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?
I added two scsi disk, but it is not listed in /dev. But the controller information is available from lspci code...
View 4 Replies View RelatedCan an unattended Kickstart support both IDE (hda) and SCSI (sda)? The goal is to to create a new virtual machine from scratch. What I have works for Parallels in which a new VM defaults to emulate an IDE hard disk. It does not work for VMware Workstation which defaults to emulate a SCSI disk.
The relevant Kickstart section: bootloader --location=mbr --driveorder=hda --append="rhgb quiet"
clearpart --all --initlabel --linux --drives=hda
part /boot --fstype ext3 --size=100 --ondisk=hda
part pv.2 --size=0 --grow --ondisk=hda

logvol swap --fstype swap --name=LogVol01 --vgname=VolGroup00 --size=1024 --grow --maxsize=2048
Can the Kickstart file be made to not care what drive type is there, or conditionally handle either type?
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've just put together a Centos 5.2 system using an old Future Domain SCSI card which would allow me to hook up an external DAT drive. On its BIOS screen it advertises itself as an AHA-2920 which should be handled by the aic7xxx module. However, the module doesn't even get loaded unless I force it in /etc/rc.modules and even then it doesn't pick up the card.

I checked dmesg and there are no errors.Also, interestingly /proc/scsi/scsi is empty.

using ubuntu 9.10 quick summary: need to set my tv resolution to 1840x1036 to see the whole desktop without cropping i just got a panasonic plasma tv and am trying to use it to watch movies from my computer. I hooked it up using my graphic card's dvi out. Since the TV came with a dvi to hdmi adapter I just had to buy a hdmi cable and now its set up to run under 1080p input. So I got 1920x1080 resolution for the tv. The problem is that the resolution does not fit exactly into the tv's screen. I am missing about 30 pixels top & bottom and some on the sides too. This results in me seeing my desktop on my tv, but the top panel with the applications menu etc is just out of bounds.
Under windows xp I have the same problem, but the nvidia control panel there has an option to "Adjust desktop size and position" which kind of works. Well you can resize but you cant position the picture. Resizing makes my actual resolution 1840x1036 pixels. With that resolution my left rigth top and bottom edges are all inside the TVs screen. Now i tried to do this in ubuntu using nvidia-settings and manually editing xorg.conf, but I am having no success at all. Nvidia or the x server or something is totally ignoring any modlines I include for my second screen (tv), and always shows 1920x1080 ... I have no way to scale the picture from the tv menu so I need to scale it in ubuntu. Does anyone know how to do this ?
I'm trying to install Xubuntu 10.4 on a Panasonic Toughbook CF-29 (Pentium M 1.4, 768MB ram). I downloaded the i386 desktop iso and burned it to a disk to install. When I go to install it freezes though. I tried it a couple times and one time when it froze I hit ALT-F1 and I saw this error message about squashfs repeating over and over. I thought maybe it was a bad disk at first so I burned another one and tried, same issue though. Then I thought maybe the ISO was bad so I downloaded another one from a different server.
Burned another disk same issue. Ran md5sum util on the ISO it is is definitely good. Was able to try one of the disks in another computer and it was able to work as a live cd (which it would not on the toughbook). This toughbook is known to be good because I have a Ubuntu 9.10 live CD that runs on it and I tried installing XP on it and that worked. I don't think there is any problem with the computer. So, I'm stuck. It looks like I have a good disk and a good computer. Why won't the two cooperate with eachother? How to get this to work?

I have a Panasonic G1 digital camera this outputs raw files in Panasonic's own format (suffix .rw2). UfRaw and RawTherapee can both read these so I can work on them in ubuntu (though ufraw displays a very overexposed image at first). f-spot has problems and displays a funny pinkish mess.
Can I get F-spot to display .rw2 thumbnails?
I would actually like to get Gnome to be able to display panasonic raw thumbnails as well. Is this possible?
As an aside it would be one in the eye for windoz as Panasonic have not released a codec for XP, only for Vista and 7 (and it seams to have a nasty hook in it according to dp review)

View 2 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?
