小弟最近出差，干了个活，或许是幸运，或许是水平有限，把过程贴出来，给各位大大看看，多指点
奇遇，3310的恢复
硬件配置：sun880*2，各有72G*6；
sun StorEdge3310*1，单控制卡，有36G*6；
连接方式：单通道，双主机
raid做法：8，9，10，11，12做成raid5，13作hot spare
软件配置：Solaris 9
问题描述：3310阵列有蜂鸣报警，***-反复，LED正常，无黄灯亮；
2号主机不能访问阵列，有I/O ERROR；
1号主机对阵列的访问断断续续；
数据库不能读写。
处理过程：
1、安装sccli软件
1) # cp 2.0.0_sw_solaris-sparc.zip /tmp
2) #unzip 2.0.0_sw_solaris-sparc.zip
3) # cd solaris/sparc
4) #pkgadd -d . SUNWsscs
2、用sccli察看阵列情况
#sccli selected device /dev/rdsk/c2t0d0s2 [SUN StorEdge 3310 SN#080CD3]

==========================
从上述情况来看，分析如下：
1) Ch0 ID 10 failed , need replace
2) Ch0 ID 9 , ID13 status " NONE USED " , raid 5 " DEAD "
我觉得9号和13号盘有修复的可能性，如能够修复，raid5还有希望，数据还有可能保存，就好比：干，九死一生，不干，十死无生。
3、修复
sccli> show ip-address
192.1.1.68
通过网线登陆telnet 192.1.1.68
选择VT100模式，ctl+L刷新屏幕
- go "view and edit SCSI Drives"
- select ID9 (NONE/USED)
- select "add Global spare"
- designate ID9 global spare
- go to "view and edit configuration parameters"
--> select Disk Array parameters
--> select rebuild priority and set it to "Normal" or "improved",
(when selecting "improved" ， their I/O may beimpacted)
失败，ID9 BAD
失望中，我突然发现 ID10的状态居然变成了online
好机会阿，再试试ID13
- go "view and edit SCSI Drives"
- select ID13 (NONE/USED)
- select "add Global spare"
- designate ID13 global spare
- go to "view and edit configuration parameters"
--> select Disk Array parameters
--> select rebuild priority and set it to "Normal" or "improved",
(when selecting "improved" ， their I/O may beimpacted)
ok，logical的状态变成了good，呵呵。
叫来了备件，为了安全起见，叫来了3块，把9，10，13都换掉了。 |
