服务器槽位为空,新上盘
1、安装制作raid的软件
目前使用的是storcli,把软件传至需要换盘做raid的服务器
2、安装
rpm -ivh storcli-007.0813.0000.0000-1.noarch.rpm
3、默认目录
/opt/MegaRAID/storcli
可以创建软连接
ln –s /opt/MegaRAID/storcli/storcli64 /bin/storcli
4、raid制作
查看控制id
cd /opt/MegaRAID/storcli
./storcli64 show
查看新插盘的状态
./storcli64 /c0 show
如果盘的状态不是good,得先设置成此状态
./storcli64 /c0/e24/s7 set good
./storcli64 /c0/e24/s7 show
做raid
./storcli64 /c0 add vd r0 drives=24:7
#24代表eid,7代表slot号
如果制作不成功,可以关闭jbod或者完全初始化此磁盘(slot号一定不要搞错)
./storcli64 /c0/e24/s7 set jbod=off
./storcli64 /c0/e24/s7 start initialization
./storcli64 /c0/e24/s7 show initialization
5、校验
lsblk #查看有没有新盘出现
槽位不为空,更换新盘
1、先确定需要更换的盘对应的target id lsscsi [root@node-6 storcli]# lsscsi
