跨DAE创建RAID10问题

如果已经建好的RAID Group, 可以用navicli或naviseccli getrg去查看配置情况.

下面是个举例:

navicli -h getrg 100

RaidGroup ID: 100

RaidGroup Type: Unbound <- Displays as unbound, but note how disks are listed.

List of disks: Bus 0 Enclosure 0 Disk 0 <- primary 1

Bus 1 Enclosure 0 Disk 0 <- secondary 1

Bus 0 Enclosure 0 Disk 1 <- primary 2

Bus 1 Enclosure 0 Disk 1 <- secondary 2

Bus 0 Enclosure 0 Disk 2 <- primary 3

Bus 1 Enclosure 0 Disk 2 <- secondary 3

List of luns: Not Available

Legal RAID types: r5 r0 r1_0 <- notice that different RG types are available

Now perform the BIND operation for the LUNs:

navicli -h bind r1_0 -rg

navicli -h bind r1_0 0 -rg 100 -sq mb -cap 10 -sp a

Take a look at the getrg output again:

navicli -h 10.5.43.206 getrg 100

RaidGroup ID: 100

RaidGroup Type: r1_0

List of disks:Bus 0 Enclosure 0 Disk 0 <- primary 1

Bus 0 Enclosure 0 Disk 1 <- primary 2

Bus 0 Enclosure 0 Disk 2 <- primary 3

Bus 1 Enclosure 0 Disk 0 <- secondary 1

Bus 1 Enclosure 0 Disk 1 <- secondary 2

Bus 1 Enclosure 0 Disk 2 <- secondary 3

List of luns: 0 <- Notice that a LUN number is shown

上面的例子当中, Raid Group没有创建LUN的时候,显示的磁盘顺序是上面的结果. 创建了一个R10的LUN以后,显示的下面的顺序. 注意顺序的变化.
