1. HP MSA2312FC操作

创建新卷 : 

create volume vdisk vd01 size 758G vd01vol5
create volume vdisk vd02 size 918G vd02vol1
create volume vdisk vd02 size 580G vd02vol2

创建卷和主机的映射关系 

map volume access rw lun 5 host 192168001009_0 vd01vol5
map volume access rw lun 6 host 192168001009_0 vd02vol1
map volume access rw lun 7 host 192168001009_0 vd02vol2
map volume access rw lun 5 host 192168001009_1 vd01vol5
map volume access rw lun 6 host 192168001009_1 vd02vol1
map volume access rw lun 7 host 192168001009_1 vd02vol2

2. 系统层面

配置完存储后, 通过 fdisk -l 看不到新加的存储.

通过dmesg信息可以看出, Linux SCSI 层不能自动remap LUN的关系. 具体信息如下 :

解决办法 : 

重新扫描设备, 执行以下命令, 执行完后设备就找到了. 

find /sys/class/scsi_host/host*/scan | while read line; do echo - - - > $line; done

到这里存储设备添加就算完成了.

【其他】

1. 如果存储块设备是通过iscsi连接的, 可以使用iscsiadm.

【参考】

1. man iscsiadm

2. find /sys/class/scsi_host/host*/scan | while read line; do echo - - - > $line; done
