開源虛擬磁帶庫MHVTL 安裝on RHEL6.2

server端使用RHEL6.2

client使用windows 2008

一、安裝MHVTL

1、安裝需要的rpm包

yum -y install zlib-devel mtx mt-st lsscsi kernel-devel kernel-headers sg3_utils gcc

2、安裝mhvtl，
編譯核心

3、設定開機自啟動mhvtl服務

[root@MHVTL mhvtl]# chkconfig mhvtl on

檢視生成的檔案 和配置檔案目錄

檢視配置檔案，預設每個磁帶大小500M

二、配置iscsi

安裝scsi-target-utils 執行以下命令，RHEL6.2 DVD裡面有install scsi-target-utils 這個包

[root@MHVTL mhvtl]# yum -y install scsi-target-utils

啟動服務，設定開機自啟動

檢視現有的target配置

新建一個target配置，並檢視

檢視現有的驅動器和機械臂

新增機械臂和驅動器到已建立的target

上一步報錯tgtadm: invalid reques，解決方法：先關掉selinux

檢視現有的target配置

[root@MHVTL kernel]# tgtadm --lld iscsi --op show --mode target

前面命令有好多在截圖裡，在這裡列出
  tgtadm --lld iscsi --op show --mode target
  tgtadm --lld iscsi --op new --mode target --tid 1 -T iqn.2014-08.com.example:storage.vtl.liuzhen
  tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 --bstype=sg --device-type=pt -b /dev/sg10

  tgtadm --lld iscsi --op show --mode target
  tgtadm --lld iscsi --op bind --mode target --tid 1 -I 10.1.1.0/24

使用tgtadm可以配置targets，但只是臨時生效，重啟tgtd服務後，配置全部消失

如需永久生效，使用下面的方法修改配置檔案，修改完後重啟tgt服務即看到效果

[root@MHVTL tgt]# pwd

/etc/tgt

[root@MHVTL tgt]# tail targets.conf

<target iqn.2014-08.com.mhvtl75.nbusyd.com.liuzhen:mhvtl.target1>

       device-type pt

       bs-type sg

include /etc/tgt/mhvtl_targets.conf

       allow-in-use yes

</target>

[root@MHVTL tgt]#

[root@MHVTL tgt]# cat /etc/tgt/mhvtl_targets.conf

backing-store /dev/sg10

backing-store /dev/sg2

backing-store /dev/sg3

backing-store /dev/sg4

backing-store /dev/sg5

檢視target狀態   ，下面命令和 tgtadm --lld iscsi --op show --mode target 功能基本一樣

 配置完成。

 此次只是做了簡單的連線使用測試，使用的是0.18版本，目前已經有1.5版本，還有很多細節需要完善，以後再一一測試。
