Server :: Enabling Encryption On LTO4 Tape Drive?

Oct 22, 2010

I didn't know if I should have posted this in newbie, hardware, or server. I haven't used tape drives in Linux previously; however I'm trying to figure out how to enable an LTO-4 tape drives built in encryption. Im not that concerned with secure key management, I am looking to just being able to load a key into the drive and get the tape to encrypt. Im for a simple command, but I dont even know where to start. If it varies by device, its an HP Ultrium 4 (1760).

Feb 28, 2011

I am running Ubuntu 10.04, and i recently purchased an tandberg LTO-4 SAS tape drive. I want to access it and backup data on it. Do I simply just connect plug it into the server,and I should be able to backup/transfer data to the tape drive? Or are there intermediate steps before I can do that. Here are some results from commands that I have typed:

Debian Hardware :: Getting HPE Library And Tape Tools To Recognize Tape Drive

Apr 3, 2016

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

Ubuntu :: Use The Tar Command With A Tape Drive - Data Is Larger Then 1 Tape

Mar 8, 2010

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.

CentOS 5 Hardware :: Scsi Drive Not Recognized?

Feb 21, 2009

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

Disk /dev/cciss/c0d0: 72.8 GB, 72833679360 bytes
255 heads, 63 sectors/track, 8854 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/cciss/c0d0p2 14 8854 71015332+ 8e Linux LVM

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?

Debian Hardware :: Tape Support Still Active For Old Drives?

Dec 24, 2010

Last month I found an old Seagate Hornet tape drive (STT20000A) with 2 TR-5 tapes at a thrift store. After sitting on a shelf at my place until last week I put it in an old system and installed Debian 5 on it. After a long time of working on it and never finding any useful help newer than 2007 I'm about to put it on eBay. So, here's a few questions:

Can this work in Debian 5 or should I put 4 or older on the system? If I put older linux on it, could I still get ide-scsi module working? apparently it has be obsolete for some time. The main problem is that it locks up the system when I try to write to it.

Hardware :: Ensure A USB External HDD Gets Assigned The Same SCSI Id?

Feb 3, 2009

I have 3 WD External USB hard dives. 2 are the same and are rotated for backup purposes and my system assigns them both to /dev/sdb (one is only plugged in at a time), this is fine.The 3rd drive is used for a different purpose and may or may not be plugged in at the same time as one of the others.How can I make the 3rd drive be allocated to /dev/sdc all of the time whether one of the other drives is plugged in or not?

Apr 30, 2010

I'm going to replace damaged HDDs in my server with new drives, which have sector size of 4096 bytes instead of 512. Does CentOS natively support such drives? If yes, since which version? If no, what actions should I take to correctly prepare such a drive to work. How to check that such a drive is correctly recognized by OS?

General :: CentOS 5.5 - External DVD Drive Does Not Show Up

Dec 5, 2010

Installed CentOS 5.5 some time ago and I can proudly say I am more than satisfied with it. Managed to install codecs, flash player, media players, chrome and opera browsers and all other things I need. My only problem is that as of about a week ago my external DVD player is not recognized any more by CentOS so I am unable to watch movies. My external DVD player is Magnavox and it works great but CentOS does not recognize it any more. I used to watch movies in CentOS in SMPlayer all the time. What to do to get it back?

CentOS 5 :: Installed 5.3 On An External USB Drive But Can't Boot From It

Oct 5, 2009

I recently installed CentOS 5.3 (from DVD media) on a Seagate 320GB external USB drive; this drive is connected to an Intel-based desktop computer (Intel D945GNT motherboard) with two internal SATA drives (both NTFS, as I'm running Windows XP SP3 as my primary OS). The install found the USB drive fine, and I manually configured my partitions; I had the install place the boot loader in the first sector of the boot partition of the external USB drive. I had set my BIOS to boot from the USB drive first; after a reboot, nothing happened...no GRUB menu, nada.

After some research, I had found an article discussing the need to rebuild the initrd for USB drive support. So, I booted the computer from the CentOS DVD, then went into 'linux rescue' mode; once I was at a command prompt, I navigated to the /boot directory and executed the following command:

mkinitrd --with-usb --preload=ehci-hcd --preload=usb-storage --preload=scsi_mod --preload=sd_mod ./usbinitrd-2.6.18-128.el5 2.6.18-128.el5

After the new "usbinitrd" was created, I edited grub.conf to reflect the new image, then attempted the reboot again from the USB drive. Still no GRUB menu.

CentOS 5 :: Anaconda Unmounting DVD From External Drive

Oct 25, 2010

I have an external DVD burner hooked up to an EEE PC 701SD. The disk has worked on a dell desktop computer, and a 701 (the first eee pc which I built the install on) without a problem, however when I boot up the install disk on the 701SD, I get a message telling me it's unable to download the kickstart file. It's being set to cdrom:/ks.cfg, which should work, but it isn't.... This exact same disk just did a full install on the 701 15 minutes before I ran it on this computer.

CentOS 5 Hardware :: Can't Boot With External USB Drive Installed?

Sep 30, 2009

I installed the latest download of centos 5 on to a older dell optiplex gx260. install went fine. I then hooked up an external 1tb USB drive, formatted it ext3 from inside the LVM, and mounted it to /usb-mnt. the mount command is in /etc/fstab like normal: /dev/1tb-usb/1tb-usb /usb-mnt ext3 defaults 1 2

all of the steps taken were straight out of the gui now on boot up I get: checking filesystems fsck.ext3" No such file or directory while trying to open /dev/1tb-usb/1tb-usb [FAILED]

*** an error occurred during the file system check
*** Droping you to a shell; the system will reboot
*** when you leave the shell.
give root password for maintenance
(or type control-D to continue):

and yeah all the /dev entries are gone. I have rebooted in linux rescue mode from the install cd, commented out fstab and been able to boot. but that doesn't actually get me to having this disk available. how to I get the system to see the drive again? if I add it back to fstab is just goes into the above. I don't seem to be able to get LVM to see the disk anymore to reformat it, I can't get the system to allow me to access it so I seem stuck.

so how do you get the system to reprobe and add a drive that once existed? uname -a output: Linux guff.domain.edu 2.6.18-128.el5 #1 SMP Wed Jan 21 10:44:23 EST 2009 i686 i686 i386 GNU/Linux

Fedora Servers :: Tar And Mt Commands For Tape Drive?

Feb 26, 2010

I'm having issues with mt commands. For some reason, my server doesn't like backing up directories using tar.

Code:

# tar -czf /dev/st0 /www /home

ends up giving me an error message saying "removing / prefix" and then using the command

Code:

# mt -f /dev/st0 status

gives me an IOCTRL error. I've googled the error code and haven't come up with a viable fix. Thus far, the only way I've been able to check which files are on the tape is:

Code:

# tar -tzf /dev/st0

Of course, without getting the actual directories on the tape in the first place, the only files I've been able to transfer at this point are just singular files within the directories as opposed to the entire directories themselves.

Red Hat :: Make A Hard Disk Act Like A Tape Drive?

May 4, 2011

I have a linux server running Red Hat Enterprise Linux AS release 4 (Update 8) that I need to do some unusual configurations to. I have a hospital application written using a database called MSE. Now the provider of this application says they will only support tape because of the fact that this system is using a specialized backup system. Basically the data is housed on raw_data blocks. So what I am looking to do is create a way to USE the SAN to present the server with Hard Drives and be mounted as if it was a tape. Has anyone tried to do something like this before? If so how did you configure that. One solution that I thought would be to just Present a 2TB lun and carve up several partitions cut not create filesystems on them. Then just create a symlink everynight /dev/rmt0 and rotate out the partitions.

Hardware :: Bacula - Setting Up Tape Drive Backup

Sep 15, 2010

I am setting up a tape drive back up, but I am having "fun" with bacula configuration. Basically the drive is working , I ran the test with the btape program and all was correct. I am basically meddled up with the jargon and the very large bacula documentation. I created some 2 volumes and gave the mounted the tapedrive (labeled) the name of one of them "tapevol2" .... now I can not relabel the tape, I deleted the volume "tapevol2" but still the tape drive is mounted with that name, even though the volume is deleted. If I add ( create more volumes) I can not make the tape to mount with anything different that "tapevol2". I would like to go back to zero and delete all volumes, and mount the tape with one of the newly created volumes, so the jobs back up can run.
