PMC相关RAID卡信息查看方法
摘要
昨天简单整理了LSI相关设备的信息
今天计划学习下PMC相关的RAID卡信息.
也就是偶昨天storcli 查看 controller为0 的情况.
感觉部分服务器大部分使用LSI 小部分私用PMC的raid卡
Raid卡的简介
跟摘要里面说的一样, 我这边遇到的Raid卡主要有两种
LSI 还有 PMC
其中LSI的历程:
惠普的芯片制造->安捷伦->私有化改名安华高->收购LSI->收购博通(改名博通)
PMC的历程:
Microchip 收购 Microsemi
Microsemi 收购 PMC
所以现在PMC的Raid卡其实是属于 Microchip的.
举个例子LSI的Raid卡一般名字是 9361-8i
如果是PMC的Raid卡可能是 PM8204 Raid卡
比如浪潮的 Inspur 8204 使用的应该就是MicroChip公司的芯片.
他们公司的工具就可以使用.

注意需要选择 Storage Manager Downloads 下载

Linux下安装
linux的安装包最为庞大.选择具体版本就可以进行安装了.
rpm -ivh kmodxxxx
注意安装完之后文件路径为:
/usr/Arcconf
arrconf的简单使用
cd /usr/Arcconf
./arcconf list 1
# 注意控住器的信息主要如下:

先进行简单的写入测试
命令:
dd if=/dev/zero of=test bs=8k count=10000 oflag=direct
结果:
记录了10000+0 的读入
记录了10000+0 的写出
81920000字节(82 MB)已复制，0.738322 秒，111 MB/秒
命令:
dd if=test of=/dev/null bs=8k count=10000 iflag=direct
结果:
记录了10000+0 的读入
记录了10000+0 的写出
81920000字节(82 MB)已复制，1.49706 秒，54.7 MB/秒
设置一下raid的缓存比率
命令报错了. 好像还需要别的命令.
./arcconf setcache 1 cacheratio 10 90
Controllers found: 1
No Logical device(s) is configured with controller caching.
Command aborted.
学习下命令:
./arcconf SETCACHE 1 LOGICALDRIVE 0 con
./arcconf setcache 1 cacheratio 10 90
发现命令依旧报错:
./arcconf SETCACHE 1 LOGICALDRIVE 0 con
Controllers found: 1
The specified operation cannot be performed as SSD I/O bypass has been enabled on array 0.
Command aborted.
放弃 !-_-!
