【虚拟带库】mhvtl虚拟带库安装与配置

1、配置存储磁盘至linux as 5上面
[root@linux02 vtl]# lspci

[root@linux02 vtl]# cat /sys/class/fc_host/host1/fabric_name

[root@linux02 vtl]# fdisk -l

Disk /dev/sda: 268.4 GB, 268435456000 bytes
255 heads, 63 sectors/track, 32635 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sda doesn't contain a valid partition table
[root@linux02 vtl]#
[root@linux02 ~]# fdisk /dev/sda
The number of cylinders for this disk is set to 32635.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): d

[root@linux02 ~]# mkfs.ext3 /dev/sda1

2、安装kernel-devel包

[root@linux02 vtl]# uname -a
Linux linux02 2.6.18-8.el5xen #1 SMP Fri Jan 26 14:42:21 EST 2007 i686 i686 i386 GNU/Linux

[root@linux02 vtl]# rpm -ivh kernel-xen-devel-2.6.18-8.el5.i686.rpm

3、在linux下安装mhvtl虚拟带库及设备配置

在安装mhvtl之前，先安装如下软件包:

[root@linux02 mhvtl-0.18]# rpm -q zlib-devel
zlib-devel-1.2.3-3
[root@linux02 mhvtl-0.18]# rpm -q mt-st
package mt-st is not installed
[root@linux02 mhvtl-0.18]# rpm -q mtx
package mtx is not installed
[root@linux02 mhvtl-0.18]# rpm -q lsscsisg3_utils
package lsscsisg3_utils is not installed
[root@linux02 mhvtl_soft]# ls

[root@linux02 mhvtl_soft]# rpm -ivh mt-st-0.9b-2.2.2.i386.rpm

接着创建vtl用户：
groupadd vtl
useradd vtl -G vtl
passwd vtl
mkdir /opt/mhvtl
mkdir /etc/mhvtl
chown -Rf vtl:vtl /opt/mhvtl

chown -Rf vtl:vtl /etc/mhvtl
解压及安装：
[root@linux02 vtl]# mv mhvtl-0.18.zip mhvtl-0.18.tgz
[root@linux02 vtl]# tar zxvf mhvtl-0.18.tgz
[root@linux02 vtl]# cd mhvtl-0.18
[root@linux02 mhvtl-0.18]# ls -lsa
total 84

[root@linux02 mhvtl-0.18]# make distclean
[root@linux02 mhvtl-0.18]# cd kernel/
[root@linux02 kernel]# date 061517322011.30

mailto:root@linux02]root@linux02 mhvtl-0.18]#cd ../
[root@linux02 mhvtl-0.18]#make;make install

安装完成后启动mhvtl:
[root@linux02 mhvtl-0.18]# /etc/init.d/mhvtl start
Could not locate library config file: /etc/mhvtl/library_contents.10
Creating a default one
Please stop mhvtl & edit /etc/mhvtl/library_contents.10 to suit your requirements

如果没有配置文件，会生成默认的配置。用lsscsi -g查看：

[root@linux02 mhvtl-0.18]# lsscsi -g

这里的/dev/sg11和/dev/sg12是机械手。
这个默认的容量是500MB，这个可以查看mhvtl的配置文件mhvtl.conf:
capacity=500就是指默认容量为500MB,64个磁带。
cat /etc/mhvtl/mhvtl.conf

# Home directory for config file(s)
MHVTL_CONFIG_PATH=/etc/mhvtl
# Default media capacity (500 M)
CAPACITY=500
# Set default verbosity [0|1|2|3]
VERBOSE=1
# Set kernel module debuging [0|1]
VTL_DEBUG=0
可以更改。
简单应用：查看机械手状态：
