Sun v245的硬RAID

Sun的215和245除了支持传统上的软RAID之外，新增了硬RAID功能。不过话说回来，这种价位上的服务器，不支持硬RAID的似乎也太抠 门了。

本文以崭新的机器作为例子，如果不是新机器――建议不要乱来。

一、先期准备：

新的机器一般都没有系统，直接开机即可进入OK模式（OK提示符）

 setenv fcode-debug? true

 setenv auto-boot? false

 reset-all 

机器重启以便生效，否则之后将会出现This must be fixed immediately using set-sas-wwid 的提示。

二、初始化磁盘

我的机器disk配置如下：

{0} ok show-disks
a) /pci@1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1/disk
b) /pci@1e,600000/pci@0/pci@1/pci@0/ide@1f/cdrom
c) /pci@1e,600000/pci@0/pci@1/pci@0/ide@1f/disk
q) NO SELECTION
Enter Selection, q to quit:

{o}ok select /pci@1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1 //选择磁盘通道

三、创建RAID卷

{1} ok show-volumes
No volumes to show

目前还没有RAID卷存在

{1} ok probe-scsi-all //查看ID

/pci@1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1

MPT Version 1.05, Firmware Version 1.08.04.00

注：如果出现ERROR: /pci@1e,600000: Last Trap: Fast Data Access MMU Miss报错，您可能需要执行

{1}ok reset-all

{1} ok 0 1 create-im-volume //注意："反向"命令

Target 0 size is 143243264 Blocks, 73 GB

{1} ok 2 3 create-im-volume

创建了2个Raid1卷，Raid 0 卷则用create-is-volume命令

{1} ok show-volumes

    Target 1        FUJITSU MAY2073RCSUN72G 0501

  Disk 3
    Secondary  Online  Out Of Sync
    Target 3        SEAGATE ST914602SSUN146G0603

 搞定！

四、删除磁盘

｛1｝ok 0 delete-volumeIXPUB技术博客 z(Wp pv0Z k`n
The volume and its data will be deleted
b2F ~k)jj&p
RR$m0Are you sure (yes/no)?  [no] yes
-e@vpf `y${0Volume 0 has been deleted

将磁盘0删除

五、重启

 setenv fcode-debug?false

 setenv auto-boot? true

 reset-all

 

安装操作系统和应用程序。部署完毕！
