I have installed, LTO-5 in rhel 5.
now i have taken a backup using command.
dump 0uf /dev/nst0 /dir
now i want to see contents of tape.
the command tar tvf /dev/nst0 is showing error
is there any other command to see dump backup contents
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 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.

I want to know how to retrival partial files from a lto 4 tape instead of retrieving the complete tape.
View 2 Replies View RelatedI 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 tried to do a listing of the contents backedup on tape and it got struck in middle throwing below error,

i removed the tape by holding the eject button and now when i try to insert another tape, it's unable to take the tape in to tape drive...
I've tried doing all except reeboting the server, can any one help me out in this issue, hope the blow information may help in debugging the issue... code....
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 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 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
I have s script that standard users use to back up usb drives to lto4 tapes.it asks for a JobNumber and sends an email upon success.I recently expanded it to use Multiple tapes.my specific Q is if the system reaches the end of the tape it happily mentions in the terminal that one needs to put in a second tape.what i would like to do is send an email that --It needs a second tape.( it presently sends an email upon successful compleation - so you see the only way a person knows that they need a second tape is if they
1-- know that the drive they are backing up is < 800GB (lto4)
2-- they do not get a completion emails and the think to walk to the basement and see the request for a second tape.
I wish for an email that would tap them on the shoulder that : " you need to put in a second tape "so -- if i know the exact syntax that shows in the terminal - which is:Prepare volume #2 for `/dev/st0' and hit return:then can i test for that somehow?
I have a bash script that I am using for doing tape backups. The meat of the bash script is
sudo tar --totals -H pax -cvf /dev/st0 *
This all works just fine.
But of course tape functions have to be ran as root, therefore sudo, requiring the standard user to enter the root password. I would like to be in a situation where the standard user does not need (does not know) the root password. I think my solution is add that standard user.
User named dog to the sudo list.
I have reviewed the sudo man page and looked at [URL]. I am still fuzzy.
1- Will adding user 'dog' to this sudo list do what I expect meaning I can run:
sudo tar --totals -H pax -cvf /dev/st0 *
and the user is not queried for the root password
2- How do I do that? and do I make a cmd alais for only: "tar --totals -H pax -cvf /dev/st0 *"
My distro is OpenSuse.
I have a Dell ml6000 as a network accessed tape library, I need to mount the tape library on my RHEL5 server as a nst* so I can setup backup crons. What is the process i need to follow to set thsi up?

im trying to clone my ubuntu system installed in a laptop in case the laptop crashes.
But, first of all: when i try to restore the system in a new PC, could be incompatibilities because the hardware of the broken laptop and the new laptop is different?
I dont mind if i have to buy another laptop with the same processor type (i386, etc), but, for example, the type of the RAM could be cause of problems?

View 2 Replies View RelatedI was having trouble creating a USB Startup Disk in Ubuntu and used the command:
sudo dd if=/dev/zero of=/dev/sdb bs=1M count=1
This was a mistake as my USB flash drive was on /dev/sdc. If I am understanding this correctly, the command above deleted the MBR and the partition table. This disk had a single "/storage" partition on it. I googled a solution and found that the "testdisk" program seems to be the most popular solution for things like this. I ran it, selected an "Intel/PC partition" type, set the partition to a non-bootable primary Linux partition, wrote it, and rebooted.
Whenever I run:
sudo mount -t ext3 /dev/sdb1 /storage
I get:
mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
Dmesg shows the following:
