This article introduces the knowledge of "how to install virtual tape library mhvtl in ubuntu". In the operation of actual cases, many people will encounter this dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1 download the source code

Download the latest version of mhvtl from the website https://sites.google.com/site/linuxvtl2/home#mhvtl-download, and I download the latest version of mhvtl-2013-10-20.tgz.

2 ensure the consistency of the kernel version

Make sure that your kernel development package is the same version as the kernel that your system is running, because mhvtl will compile a kernel module written by it. If the kernel development package is not the same version as the kernel that your system is running, it will not be loaded into the kernel when installing the kernel module in mhvtl. Although you can modify the VERMAGIC_STRING in include/linux/vermagic.h in the source code to be consistent with the current PC kernel uname-r, it is not recommended.

3 unzip the source code

Tar xvfz mhvtl-2013-10-20.tgz

4 install four packages lsscsi,sg3_utils,liblzo2-dev,mtx can be installed directly with the apt-get install command

Apt-get lsscsi sg3_utils liblzo2-dev mtx

Without the liblzo2-dev package, when compiling mhvtl, it will prompt that the file lzo/lzoconf.h cannot be found.

5 create groups and users for mhvtl

/ usr/sbin/groupadd-- system vtl

/ usr/sbin/useradd-- system-c "Vitrual Tape Library"-d / opt/vtl-g vtl-m vtl

6 compile kernel module

Cd mhvtl-2013-10-20/kernel

Make

Make install

7 compile user space code

Cd mhvtl-2013-10-20

Make

Make install

8 modify the owners of / opt/mhvtl and / etc/mhvtl directories. Mhvtl cannot be started without modification.

Chown-R vtl:vtl / opt/mhvtl

Chown-R vtl:vtl / etc/mhvtl

/ etc/mhvtl is the configuration file path, and / opt/mhvtl is the virtual tape library storage path

9 start the daemon for mhvtl

/ etc/init.d/mhvtl start

10 View virtual tape library status information

Lsscsi-g

You can see that our virtual device is hung on the HBA#6, where the mediumx type of device is a robotic arm, in this case / dev/sg13,/dev/sg14.

Run the command mtx-f / dev/sg13 status
