Solaris9:E450+A5200,mpxio问题,请指教

jsc_flying

我修改了/kernel/drv/scsi_vhci.conf;mpxio-disable="no";后重起format看到硬盘如下:

弱弱的问下我的双通道算做好吗?据说做好后应该
format看到是一套盘,如果没做好,该如何继续?

看看messages的关于scsi_vhci.conf报错，会有地提示的！或者看看启动过程！最好把你的scsi_vhci.conf贴上来；希望你的solaris9是最新的，打了最新的补丁，装了最新的san包。

以上这段有问题吧？？？
A5200的应该是 SUN     SENA
而且sun自己的存储应该不用编辑这段内容的.

修改scsi_vhci.conf之前,format只看到一套盘,修改之后如上;修改后我拔掉任何一条光钎线后,format 只看到一套盘,问:我的多路径算做好了吗?是不是只修改scsi_vhci.conf文件就OK了

松林坡

总觉得什么地方不对， 难道是A5200对mpxio的支持？  还是HBA卡对mpxio的支持？

反正逻辑设备看起来不对，应该出来wwn号的很长一串才是OK的， LZ你继续努力吧

easybegin

more scsi_vhci.conf的结果好像很怪异，原始的比这个长！

doging

应该是没做好。
