问题终于搞定了,以下为故障解决方法
Linux下使用HP MSL 6060磁带库
硬件:
服务器:Dell PowerEdge 6650
HBA卡:Qlogic 2312
软件:
OS:RedFlag Linux DC Server 4.1 SP1 x86
mtx:mtx-1.2.18-1.i386.rpm
HBA卡驱动:
(SP1系统核心默认用的qla驱动为7.02,只要qla驱动高于或者等于7.06都可以识别到机械手)
qla2x00-v7.07.
hp_qla2x00-7.07.05.
几点需要注意: 梦见飞蛾
1. 系统能否识别磁带库的机械手,主要取决于HBA的驱动;若通过HBA能够识别到磁带库的驱动器(st0)设备,而不能识别机械手,可以通过更新HBA驱动解决(HBA驱动建议用磁带库厂家提供的)
2. 系统识别机械手的设备号在重启系统之后会改变,可以通过scsidev软件来绑定
3. 使用mtx作磁带库操作建议会阅读MAN文档
使用MSL 6000
磁带库操作步骤如下:
一.
更新qla驱动
1. 确认QLA驱动版本型号
cat /proc/scsi/qla2300/2或者3,文件头会显示QLA Driver version
室内团建活动QLogic PCI to Fibre Channel Host Adapter for QLA2340 :
Firmware version: 3.03.19, Driver version 7.07.0
2. 更新驱动
tar zxvf qla2x00-7.07.06-dc4.1-sp1-ia32.zip -C /
rmmod qla2300
depmod -a
cd /lib/modules/`uname-r `/kernel/drivers/scsi
modprobe qla2300
dmesg | grep -B 10 -A 10 st0
dmesg | grep -B 10 -A 10 sg0
梦想之门
检测是否有st及sg设备挂载的信息,如
[1] 若系统能够识别出机械手,在cat /proc/scsi/scsi中会显示出以下信息,
[2] Model信息为磁带库型号:MSL 6000 ries
[3] Type信息为Medium Changer,这个type的信息无论是HP磁带库或者IBM磁带库都为此信息
[4] 请记住cat /proc/scsi/sci信息中的“Host: scsi3 Channel: 00 Id: 00 Lun: 00”,可以以此识别系统上真正的机械手挂载点

note:一般磁带库有四个驱动器(st),一个机械手(sg),N多个slot(也就是放磁带的插槽)
[1] 从dmesg信息显示驱动器已(st[0-3])已经识别
[2] 从dmesg信息显示有三个机械手,这里就有问题,需要确认哪一个是真正的机械手
从cat /proc/scsi/scsi和dmesg的信息可以判断出哪个是真正的机械手

很明显,从host、channel、id、lun的设备号可以分析得出机械手是挂载在sg42上
二. 绑定linux系统的设备名
linux系统允许为设备起便于记忆的名称,但是这带来了另一个问题,每次启动新设备的名称是可变的。如果由于管理原因,某次启动没有加载磁带库驱动程序,那么下一次启动后磁带库设备的名称有可能发生变化。特别对于设备多的时候,会造成很大的麻烦。
为了避免此麻烦,建议安装使用scsidev。
scsidev的设备名是根据设备的scsi属性对应的,scsidev的设备名即使在设备不可用的时候也不改变。
1. 安装:
引用:[root@wylonwong /root]# tar xzf scsidev-2.
[root@wylonwong /root]# cd scsidev
[root@wylonwong scsidev]# ./configure
creating cache ./config.cache
checking gcc
checking whether the C compiler (gcc ) yes
checking whether the C compiler (gcc ) is no
checking whether we are using yes
checking whether gcc accepts -g... yes
checking for yes
checking how to run the gcc -E
checking for linux/ no
checking for scsi/ yes
checking for /usr/src/linux/drivers/scsi/ yes
checking for a BSD /usr/bin/install -c
updating cache ./config.cache
creating ./config.status
creating Makefile
creating config.h
[root@wylonwong scsidev]#
[root@wylonwong scsidev]# make
gcc -g -O2 -Wall -DVERSION=\"2.22\" -o scsidev scsidev.c
[root@wylonwong scsidev]# make install
install -o root -g root -m 755 -s scsidev /bin
install -o root -g root -m 644 scsidev.8 /usr/share/man/man8
gzip -9f /usr/share/man/man8/scsidev.8
if [ ! -d /dev/scsi ]; then mkdir /dev/scsi; fi
#install -d /usr/share/doc/packages/scsidev
#install COPYING boot.diff README scsi.alias /usr/share/doc/packages/scsidev/
2. 创建scsidev的设备名:
引用:[root@wylonwong scsidev]# scsidev -sdn

th0-0c0i0l0: "6811020764"
Serial number of /dev/scsi/sgh0-0c0i0l0: "6811020764"
3. 得到scsidev设备:
引用:[root@wylonwong scsidev]# ls
/dev/scsi/
nsth0-0c0i0l0 sgh0-0c0i0l0 sgh0-0c0i6l0 sth0-0c0i1l0
nsth0-0c0i1l0 sgh0-0c0i1l0 sth0-0c0i0l0
三. 磁带库操作
1. 使用mtx包,主要用于控制机械手作导带换带、连接slot(插槽)到driver(驱动器)操作
红旗Linux DC Server 4.1有自带mtx-1.2.18-1.i386.rpm安装包,在第一张光盘,安装完之后,会在/usr/sbin/mtx
[1] mtx作检查磁带库状态操作
[root@wylonwong scsidev]#mtx –f /dev/sg42 status

从以上信息显示4个驱动器(driver)全为空,有60个slot,其中有磁带的slot显示为Full,那么我们可以做将slot中的磁带放到驱动器中
[2] 放带操作
命令格式为mtx –f 机械手设
备号 slot号 driver号
引用:[root@wylonwong scsidev]#mtx –f /dev/sg
42 load 56 0
[3] 拨带操作
引用:[root@wylonwong scsidev]#mtx –f /dev/sg42 unload 56 0
除了以上简单操作之外,还可以实现将slot移位,如将原有的slot 56的磁带移动到50,这只是逻辑上的移动;
更详细的操作请查阅man mtx
四. 重做核心
加载QLA驱动之后,必须重启系统测试QLA驱动是否加载成功,重启之后再检查磁带机的驱动器(st)和机械手(sg)是否识别到,若识别到,一切OK
[1] 备份原先操作核心
引用:cp –a /boot/initrd-`uname -r`.img /boot/initrd-`uname -r`-`date +%Y%m%d`.img
[2] 重做核心命令:
引用:mkinitrd -f /boot/initrd-`uname -r`.img `uname -r`
