服务器多路径挂载FC存储

1、服务器多路径挂载FC存储一、物理连接1、打开服务器，将HBA卡插入插槽，并将光线连接到光线交换机。注意光线如果插反会无法正常通信，也不会亮。二、存储设置2、进入存储管理界面，进行分配存储空间与映射三、服务器设置rpm常用命令参数说明：rpm-exxxxx-nodeps#RPM强制卸载rpm-ivhxxxxxx-replacepkgs#RPM将忽略软件包已被安装强行安装rpm-ivhxxxxxx-replacefiles#RPM将忽略文件冲突强行安装rootDCXZM-SR43-NF5270M3home#rpm-ekpartx-0.4.9-87.el6.x86_64-nodepsrootDCXZ

17、g。后面参数是指定希望添加到该卷组的所有分区和磁盘。vgcreate在创建卷组eccdbvg以外，还设置使用大小为4MB的PE（默认为4MB），这表示卷组上创建的所有逻辑卷都以4MB为增量单位来进行扩充或缩减。由于内核原因，PE大小决定了逻辑卷的最大大小，4MB的PE决定了单个逻辑卷最大容量为256GB,若希望使用大于256G的逻辑卷则创建卷组时指定更大的PE。PE大小范围为8KB到512MB，并且必须总是2的倍数（使用-s指定，具体请参考manvgcreate）。激活卷组rootDCXZM-SR43-NF5270M3#vgchange-aymysql0logicalvolume(s)invo
