Red Hat :: Mapping /proc/scsi/scsi Entries With Respective Device Names In /dev/ Directory
Apr 11, 2011In 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?

Jan 15, 2010One of my servers contains two scsi enclosures. After hot removing a disk and hot adding another the new disk gets assigned a device file but the enclosure (in sysfs) doesn't want to see it.
How can I force the enclosure to recognise the hot added disk.
Situation in sysfs:
The link device is dead after hot removing the device and keeps vanished after hot adding the new device. The hot added device gets assigned a device file and it is reachable. Even
Doesn't change anything.
How can I force the link to be updated towards.
General :: Detect The Scsi Device Without Restarting?
Mar 25, 2010I 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.

Server :: Adding Scsi Device Won't Show Up In Fdisk
Jul 27, 2011I 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.
View 7 Replies View RelatedHardware :: SCSI Hard Disk Device Node Creation
Mar 26, 2010I am developing for a Linux based device for which the HOT PLUG option is deactivated. As part of optimizing the code, we also don't want to create device files for unused devices. We understand that both USB attached and fixec SCSI hard disks would create device files like /dev/sda,/dev/sda1 /dev/sdb, /dev/sdb1 etc. Is this understanding correct?
In the case of USB attached SCSI devices, would driver create this device file entry? How is it created? Can somebody please tell me how it is being created automatically. In case I attach a fixed SCSI hard disk before boot up(and create device file /dev/sda1), would USB SCSI device driver create device files starting from /dev/sdb, automatically.

Hardware :: Palm Device Listed In /proc/bus/usb/devices - But Not In Lsusb Output
Sep 5, 2009When I connect my Treo 650 with a USB cable it works sometimes and not others. A little investigation showed
that it always works when I see the Palm device listed in the output of lsusb. While trying to diagnose why it appears sometimes and not others, I discovered that it sometimes appears in /proc/bus/usb/devices and not
in lsusb. I didn't think that was possible!
I've tried running kudzu (the Red Hat hardware discovery tool) and killing and restarting udevd.

CentOS 5 Hardware :: Scsi Drive Not Recognized?
Feb 21, 2009I 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
Disk /dev/cciss/c0d0: 72.8 GB, 72833679360 bytes

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?
CentOS 5 Hardware :: Panasonic LF-D201 SCSI DVD-RAM Onto 5.3
Aug 6, 2009I'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.
CentOS 5 :: Unattended Kickstart Install Supporting Both IDE (hda) / SCSI (sda)?
Apr 6, 2010Can 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
volgroup VolGroup00 --pesize=32768 pv.2
logvol / --fstype ext3 --name=LogVol00 --vgname=VolGroup00 --size=1024 --grow
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?

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.

Mar 16, 2009I'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.

Drivers exist for earlier version of Red Hat, but building an using a driver disk results in the error:

Ubuntu :: Can't Move /var/www To Other Device - Partition / Sort It?
Jun 1, 2010I'm trying to move the /var/www dir to another partition (another hard drive even, though I doubt that makes a difference) because my file system partition is rather small. But when I do I get "403 -forbidden" and in the logs "Permission denied: /home/www/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable". If I move it anywhere within the partition (and adjust the conf) I don't get this problem.
Using Ubuntu 10.04 Desktop x64. I haven't had any problems with this in earlier Ubuntu-versions.
