我有大约六台服务器，它们都在 Oneiric 服务器 AMD64 上运行 Intel RS2BL080 raid 控制器。使用 megaraid_sas 内核模块时运行正常，但当我尝试使用 megacli 探测卡时，它告诉我没有可用的 raid 控制器。
Intel 不支持 Ubuntu 操作系统，所以他们帮不了我。四处寻找后，我发现其他人也使用过这个 megaraid 控制器。
我只是想联系那些可能知道我做错什么的人。

答案1
简单的...
$ sudo setarch x86_64 --uname-2.6 /opt/MegaRAID/MegaCli/MegaCli64 -adpCount
Controller Count: 1.
Exit Code: 0x01
答案2
MegaCli 8.02.16 及更早版本不支持 uname 3.xx [1]。这个问题稍后可能会修复。
现在你需要一个解决方法[2]：
$ mkdir fakeuname
$ cd fakeuname
$ wget http://supportex.net/files/fakeuname/fakeuname.c
$ gcc -Wall -fPIC -c fakeuname.c
$ gcc -Wall -shared -o libfakeuname.so fakeuname.o
$ sudo install -m 644 libfakeuname.so /opt/MegaRAID/MegaCli/
$ sudo -i
# cd /opt/MegaRAID/MegaCli/
# LD_PRELOAD=./libfakeuname.so ./MegaCli64 -adpCount
Controller Count: 1.
Exit Code: 0x01
答案3
只需使用此指令 -http://sysadmin.te.ua/linux/monitoring-systems/smart-under-lsi-2108-kontroller.html。最好使用 megacli -LdPdInfo -aAll 来获取每个虚拟驱动器的 ID 列表。问候。
