redhat6 安裝虛擬帶庫筆記

作業系統版本
[root@node1 ~]# cat /etc/issue
Red Hat Enterprise Linux Server release 6.0 (Santiago)

先安裝一些 scsi和磁帶機相關的軟體包：
zlib-devel
lsscsi
mt-st
mtx

另外需要安裝 liblzo2-dev 包 作業系統光碟上沒有此安裝包 .
還是下載RPM包安裝快捷

liblzo2_2-2.03-6.el6.i686.rpm
上傳安裝完成。

操作過程：

報錯原因是開始沒有安裝lzo2,安裝完成後，可以再次啟動mhvtl !

再次啟動mhvtl

[root@node1 ~]# /etc/init.d/mhvtl start

這些與Storage Element對應，對應每一盤磁帶
透過命令 mtx -f /dev/sg11 status 檢視有磁帶的槽位，sg10有32個 sg11有40個
正好共有72個磁帶，每個預設500M，如果要測試備份，需要擴充套件/opt的容量
