I agree, the php web tool is very cool.
Manually updating the config files in /etc/mhvtl is a pain. Anything to automate/make this simple "is a good thing". Re: Backup software. You have lots of options here. But you do need something. Tape devices are 'sequential' devices and the data can not be accessed like a disk. Standard unix tools are 'tar' (Tape ARchiver), and cpio. These can write to tape. You need to manually load/unload tapes and handle situations where the tape becomes full. The utility 'mtx' can be used to control a medium changer. Bacula and Amanda are two open source backup software packages. I've had reports that bacula works well. Commercial software includes: - NetBackup - NetWorker - TSM - BackupExec - ArcServe Re: MAP. This is a (relatively) standard acronym for "Media Access Port". Other comon names are 'mail slots', 'Cartridge Access Port' SCSI Standard call them 'Import/Export Elements'. i.e. It's the access port to put/extract media into/out-of the library. Yeah, I know, doesn't really make sense for a VTL. But I designed this to emulate real hardware so I can support backup software in my day-to-day job (NetBackup). Lots of features within the mhVTL do not make much sense for a VTL, but are there so I can see/test/emulate real hardware situations. Cheers |

Hi Satya ...
this is a link to a post with "step by step" instruction to install and configure mhvtl : http://mhvtl-linux-virtual-tape-library-community-forums.966029.n3.nabble.com/Centos-5-6-Mhvtl-Scst-WebGUI-GUIDE-STEP-BY-STEP-td3149346.html

Hi crippa,
That was good I have already configured in my RHEL 5.4 machine , The tape drives are also visible through the php web access. But the prob is I need to have a backup software where I can work and learn take the backup and restore the files. One of my friend replied me that there are open source s/w like amanda and bacula. Can we not have veritas netbackup kind of environment where I have master and media servers. and storage is attached to media servers and where I can access the tape drives and so on.... I knew my question would be like an unreal kind of thing, But as we are techie guys , I hope we would have a solution for my unrealistic question. Anyways veritas netbackup is licensed s/w but would there be any trial versions so that I can install them and work around with it...... I would be grateful to you guys.... Awaiting for valuable replies cheers, Albatross |

There are no trial versions for NetBackup as far as I know ...
But, If you like to try TSM by IBM, you download and use for 30-40 days or so : ftp://ftp.software.ibm.com/storage/tivoli-storage-management/maintenance/ Or NetWorker by EMC also gives you a 30-45 days trial as well: ftp://ftp.legato.com/pub/NetWorker/Cumulative_Hotfixes/7.6/ You will be able to re-install to renew the trial periods for both TSM and NetWorker if you like also .. -nia |

Hi
I just wanna tell you that I finally installed netback up software verison 5.0 in my Win 2k3 machine. But I am not having any idea how to configure these MHVTL virtual tape drives with wink2k3 box. I have installed on RedHat box and working fine. all the drives are visible. So This box is acting as media server for me ??? if I am not wrong ....or do I need to install separately. Is there any s/w that we can install on windows too as we did it on REdhat box. when I am going to configure master server in the win2k3 box it is asking for configuring the devices, also popping up that there should be removable media attached to it. But there is no such media attached to the Master server. I have also installed NBU client successfully. I dont have any Idea how to configure a default environment thats with 1.Master server with storage attached to it, 2. Media server with Media attached to it ( In my case Redhat Box with MHVTL ) 3. Client My environment in the VM workstation consists of one Win2k3 box ( Master server ) one xp box ( client ) and one redhat box ( where MHVTL is installed ) So suggest me what to do how can I connect this and how to make my environment successfully run...... Waiting for your valuable replies........ Cheers, Albatross |

You need to' install a iscsi target software like scst or tgtd. For tgtd in redhat simple install via yum. In W2K3 connect via iscsi initiator.

Have I configured mhvtl in a right way or did I commit any mistake... when I fire fdisk -l in redhat it shows [root@vtl ~]# fdisk -l Disk /dev/sda: 16.1 GB, 16106127360 bytes 255 heads, 63 sectors/track, 1958 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 6 48163+ 83 Linux /dev/sda2 7 515 4088542+ 83 Linux /dev/sda3 516 776 2096482+ 82 Linux swap / Solaris /dev/sda4 777 1958 9494415 5 Extended /dev/sda5 777 1958 9494383+ 83 Linux Disk /dev/sdb: 10.7 GB, 10737418240 bytes 255 heads, 63 sectors/track, 1305 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 1305 10482381 42 SFS This is the below entry I have given in the /etc/iet/ietd.conf file, Target iqn.2009-01.com.cool:abcd.1234 Lun 0 Path=/dev/sda Alias iSCSI-TAPEDRIVE also tried to change the drive and made entry Target iqn.2009-01.com.cool:satya.1234 Lun 0 Path=/dev/sdb Alias iSCSI-TAPEDRIVE /etc/init.d/iscsi-target service is started successfully, I am able to get the target id there in windows . But unable to find the tape devices in the device management.... Also I tried to install device drivers from bin folder of veritas it work out.... is there any thing I need to change , But I am not able to find the tape devices in the win2k3 system. I have sucessfully configured veritas 6.5 Help me out ..... I would be very grateful........ waiting for your valuable replies.............. cheers Albatross..... |

Hi .... iscsi-target is effectively tgtd ..... you have done the correct procedure to install it.
[root@vtl ~]# lsscsi -g This seems to be ok
I don't understand why you have created a config file pointing to /dev/sda and /dev/sdb. Due to your fdisk sda and sdb is your primary/secondary disk where os resides. You need to pass to W2K3 via iSCSI the library and tape drives. So not /dev/sda and /dev/sdb.
You need to create config for /dev/sg10-2-3-4-5 and /dev/sg11-6-7-8-9 for having both libraries to work. Unfortunately I'm not on my Server so I can write out a running config ..... maybe Nia can help you if he is on a PC.
Or finding in the forum for a sample running config. Maybe you want to install MHVTL-GUI developed by Nia and available via Git-Hub. Some post before , i've writed a step-by-step guide for installing mhvtl on centos 5, follow the steps for installing mhvtl-gui and remember to disable selinux.
After that you can use the gui to write the tgtd config for you. /etc/init.d/iscsi-target service is started successfully, I am able to get the target id there in windows . Same as before Crippa Andrea |

Hi Crippa,
Can you tell me how to create config for /dev/sg10-2-3-4-5 and /dev/sg11-6-7-8-9 for having both libraries to work. I have succefully installed GUI its showng this way ![]() Also if there is any step by step procedure I Would be grateful to you... Cheers Albatross... |
Hi, I'm not an a PC, but I remember a menu (Remote Client) and then the tgt section (different from the scst section) If the service is already started, you can use the auto-create configuration button and let the Gui to do the work for you.
Then , simple connect the iScsi dev from w2k3. Bye Crippa Andrea |

Hi,
I am unable to create the config file in graphical way for /dev/sg10-2-3-4-5 and /dev/sg11-6-7-8-9 for having both libraries to work. when I log in to webconsole and try to config its not working out. when I go to remote clients and hit on button it gives SCSI Target via STGT (http://stgt.sourceforge.net/) link it gives me the below way.. ![]() and when I hit start for the service it is starting but the state is stopped... It is giving the following ![]() so got source an tried to compile. I tried to start the scst services but failed [root@vtl scstadmin-2.1.0]# /etc/init.d/scst start Loading and configuring the mid-level SCSI target SCSTFATAL: Module scst not found. [FAILED] It says scst module not loaded I have downloaded the scst package from sourceforge and compiled...but no luck in installing scst... I have installed scsi-target but unable to get tape drives in win2k3 box via iscsi initiator..I am able to get the iscsi partition created on redhat box on which mhvtl installed....but not tape drives... I dont know what to do ..... please help me out.... cheers, Albatross |

Hello,
The GIT Repo for stgt has been down for few days now, so the Web Console installer will not work .. Try to download directly from http://stgt.sourceforge.net/releases/tgt-1.0.19.tar.gz Once, installed, then try to configure via the Web console. Also, make sure mhvtl is already started before. -nia |

Hi Nia,
That was great. I have installed and start the service of tgt in web console.. it worked But when I tried to configure Create Automatic iSCSI Configuration its throwing error. I have jpeg for that please look into it and guide me what to do... ![]() Its giving errors like begin failed --compilation .......you can find it at the bottom of the jpeg... above... Also when I hit the same automatic configuration of STT SCSI config...its throwing below error.... Automatic STGT iscsi Target : --------------------------------------- Creating Target for mediumx /dev/sg10 TARGET 1 iqn.1994-05.com.redhat:db3dadc764d:mhvtl:stgt:1 tgtadm: this target already exists STATUS=0 Failed ... --------------------------------------- Exporting Target iqn.1994-05.com.redhat:db3dadc764d:mhvtl:2 to ALL ... tgtadm: this access control rule already exists STATUS=1 Failed ... cheers Albatross |

Regarding the Perl Config...General.pm error, it may be fine and should not affect your iSCSI targets, but if you install the following it will fix it # yum install perl-Config-General
Regarding already exists target errors, this is probably a result of rerunning automatic config again .. to restart clean, just stop/start stgt then rerun the Automatic Target Creation again. But as this looks, you should be ready to connect from your iSCSI Windows host. -nia |

I assume this was taken earlier, otherwise you wouldn't be seeing devices in next screen shot.
I dont have URL handy, but I've seen it on this forum before.

What kind of backup software are you plan to use ? For Tivoli I know that there is the TSM driver ..... You need to download and install them. Again i'm not on my home PC so i can't give you the ftp address ... maybe you can try a search on the forum or wait this evening ..... ;)
