General :: RedHat ES5 Attempting To Read Tape Contents On Quantum Superloader3
Sep 24, 2010
I have a Dell PE2900 SCSI'd out to a Quantum SL3. I'm attempting to read/display the contents of the tapes or maybe dump the displayed contents or table of contents to a file.
I can see and access the library:
]# mtx status
Storage Changer /dev/changer:1 Drives, 16 Slots ( 0 Import/Export )
Data Transfer Element 0:Full (Storage Element 1 Loaded):VolumeTag = NGL930L3
Storage Element 1:Empty
Storage Element 2:Full :VolumeTag=NGL985L3
[Code]....
But when I try running tar -tzf /dev/changer or tar -tvf /dev/changer I just get a flashing cursor and the drive sits at IDLE.

I am trying to use "hexdump" on the files in the /dev/ directory. This is ubuntu 9.10.There is some more in this forum: [URL]Hexdump returned small blocks of bytes or couldn't see the files even as root. I expected to see the actual data streams from the various devices. How come this doesn't work?

how easy it would be to read the contents of a physical disk that was part of a larger logical volume. The disk contains a "Linux LVM" partition that spans its entire size. My problem is that one of my disks died, and I have to send it back for a warranty replacement. However, the disk is dead, and I can't zero it out. I'm just trying to assess how difficult it would be (or at least how likely it would be) for a tech that's checking out the disk to get at the data.

I have been using an LTO-5 Ultrium-3000 tape drive connected to an ATTO HBA without problem. I can control the tape drive using "mt -f /dev/nst0" and have been able to make successful backups using cpio, tar, and dump/restore. I followed some instructions on the web about how to install the HPE Library and Tape Tools application (version 4.21) which relies on conversion of a rpm to a deb file. The software seems to have been installed correctly and runs. However the hardware scan function does not recognize my tape drive. The following is suggested in the user manual if the tape device is not recognized by the software under Linux:
1. Login as root.
2. Edit the following file:
vi /etc/modules.conf
3. Add the following line as appropriate:
add options scsi_mod max_scsi_luns=128
4. Reboot the computer.
The problem is I don't have an /etc/modules.conf and am not sure exactly which file would be equivalent? If this is even the correct solution.
My tape drive is controllable and functions well using "mt -f /dev/nst0 status" so it seems to be a matter of LT&T software to detect the tape drive.
At the risk of providing too much info here some, possibly relevant, output from lshw

I am looking at getting a DLT drive for my network; however, I have never used the tar command with a tape drive. What happens if the data is larger then 1 tape? Does the tar application automatically span tapes or do I need to use switches so it spans multipule tapes? Right now my Full backup will take 2 or 3 tapes.

I am trying to read the contents of a file into something else. I have a file.txt that I am working with, I want to read the file and take the data and run some commands with the data that it read. So if it read www.yahoo.com I want to be able to nslookup. Does that make sense? I have been trying to use the read command but that does not seem to work. I even was trying to read filename | > filename to see if I could even read any of the data at all. Nothing is working.

How can read the file /var/etc/allInOne.cfg and distribute its contents on multiple cfg files using C language. /var/etc/allInOne.cfg contain the data and the path of each text file.
The source file "/var/etc/allInOne.cfg "look like this:
line1
line2
...
line10
filePath:/var/etc/file1.cfg
line12
line13
...
line14
filePath:/var/etc/file2.cfg
linen
..
filePath:/var/etc/filen.cfg
the result will be :
The expected result is:
/var/etc/file1.cfg will contain line1 to line10
/var/etc/file2.cfg will contain line 12 to line13
/var/etc/filen.cfg will contain linen to linen-1

So I finally managed to get my Samba file server working () but now I have a question. On the server I have 4 folders, each being used for a certain topic. How would I set the folders as read only but not the contents, so that way remote users can read/write to the folder but can't delete or rename the folder itself? Also, if I restart the Linux box it will cease to show on the Windows Network unless I delete the Samba share and remake.

Has anyone experience of using Quantum lto 4 hh on linux? The Quantum site says it is not compatible with RHEL5 but I have downloaded a module mt-st and this seems to communicate well with the tape drive ... does this mean that the not-compatible only extends to native RHEL-5 not with the added module mt-st which adds compatibility with scsi tape drives?
If quantum will work directly on RHEL 5 then one can get Amanda up and running otherwise those lovely people at proprietary backup vendors will offer me compatibility at say 5k for commVault etc or 1k for Symantec. Also they require I find a windows server to install the base modules.

I am trying to compile Quantum's LTFS software from source on a Debian Squeeze system.
Software here:
[URL]
They provide binaries for Red Hat and SUSE, but not Debian, thus I need to compile myself.
I have installed the dependancies:
> sudo apt-get install libicu-dev libfuse-dev uuid uuid-dev libxml++2.6-2 libxml++2.6-dev
./configure completes without error.
However, when attempting to "make" I see the following:
sudo make
make all-recursive
make[1]: Entering directory `/home/station/Downloads/qtmltfs-1.2.0'
Making all in messages
[Code].....
Sitting at Heathrow airport with 30 minutes to spare, I decided to have another look at this. I have with me a 3 year old netbook running Ubuntu 10.04 Lucid Lynx NBR. Not exactly the machine I want to connect up to a Quantum LTO5 tape drive, but nonetheless, something I thought I could at least trouble shoot on.
Anyway, the software compiled without error on this machine.
This leads me to the conclusion that there is some library or path linking problem with vanilla Debian. I guess I will be installing Ubuntu on the workstation when I'm back in the office.

Ive managed to install samba, I've shared a folder. I can access from a Windows 7 machine via \ubuntupublic. I can put files in the folder form the ubuntu machine and edit them on the windows box. I can put files in the folder/share from the Windows box but then I cannot edit them on the Ubuntu machine (they are read only and have a "Lock" over them). I can fix this by going to the properties of the file/folder in Windows and manually assigning "Everybody" full control (then the lock disappears and all is well.) I want read/write access to all the folders contents from both machines all the time (security is NOT a concern I WANT the permissions wide open) what am I doing wrong?

You would think it would be easy to do this (and essential to maximizing and predicting the usage of tapes), but apparently this isn't so. The program MT(1) actually had some commands that give the block positition (if supported by the drive) from which the remaining space could be deduced (even if you couldn't predict exactly how much space the next archive would take up). However I'm using MT(1L) which no longer has such commands.

I have a Red Hat Enterprise (AS) 4.8 system and I need to know how to totally rebuild the system from dump tape. I have been making some full level 0 dumps of the system to the attached DAT72 tape drive... In the case the boot disk goes south, I need to reload from tape, onto a new disk drive. I know how to do this in Solaris. I assume you boot from CD to like a mini-root, then configure and mount the drive on temp mount points, restore the sys data, then load the "boot blocks" (like installboot on solaris).

I need help writing a script that will copy everything from tape to system directory. I have a Linux box with 3 TB of Hardware space. I am using the following commands
1) mt /dev/st0 rewind
2) tar xvf /dev/st0
3) tar xvf /dev/st0 fsf 1 (Using this to move to the next segment of the tape) and then
4) tar -xvf/dev/st0
I keep repeating steps 3 and 4.

I downloaded the DVD release of Kubuntu 10.04, from Kubuntu.org. The file is: Kubuntu-10.04-dvd-amd64.rar . I burned it to a DVD, as image, with ImgBurn application. See any problems so far? I want to dual-boot, leaving my Win7 in tact. I am confident that I can handle this with some patient instruction.

I'm a newb and have ambitions for a triple boot with MAC/W2K/#! 9.04. I first installed Ubuntu on C600 laptop and then switched to Crunchbang 9.04 since the Dell is lacking any ooomph. Now I'm trying to triple boot an HP Pavilion a330n (AMD Athlon, non-SATA board which has created problems getting Leopard to play nice, but that's another story). I removed the HD from the C600 (W2K) and replaced it with another running only #!. I installed the W2K laptop drive as master on the HP desktop with a 120GB IDE drive as slave. The 120GB drive has been partitioned for 4: MAC (35GB, ext3), W2K (35GB, NTFS), #! (40GB, ext3) and Linux-Swap (remainder, ext3).
Now to the question: I was planning on using the DD command to "xcopy" the W2K drive to the W2K partition. Sounds simple. I am trying to use the following:
dd if=/dev/sda2 of=/dev/sdb3 bs=4096 conv=notrunc,noerror
To back up a step, I saw somewhere else suggesting to boot live and run off the CD to facilitate this since I'm manipulating both hard drives. Since I'm working live, I've had some trouble sorting out password issues with root. I managed to change the root password (I know - dangerous, but only for this session anyway). Each time I try to execute the dd command, I get nada. No activity. The cursor drops below the root@crunchband:~$ prompt and just blinks. There is no important information to be lost on either drive per se, but have lost the W2K install CD long ago which is why I need to use DD anyway.

I have my local computer, and server.
I log into server, and mount my local computer (folder) via sshfs.
Create .rar backup archive direct to sshfs remote folder.
After copy, close my ssh sessions.
And use my streamer to backup files stored by server.
I'm wondering, is there any way to share streamer /dev/st0 via ssh session ?
how can i start backup direct to (remote) -> root@server/dev/st0
