2和3是同一张盘显示出来是双倍状态，执行stmsboot -e 后还是显示双倍状态，请问高手是不是sun服务器和dell磁盘阵列不兼容的问题，如何能解决这个问题呢？ @zhbzcy
对于非SUN盘阵启用多路径，除了stmsboot -e ，还需要编辑/kernel/drv/scsi_vhci.conf.

luxadm display/dev/rdsk/c2t202490B11C245F71d31s2 可以看到VendorID和 ProductID, 替换"DELL SENA" 这两个字符串。
赞。。。。。

@znnnz
按照你以上所说的我操作了一下，执行stmsboot -u 重启后还是老样子显示双倍状态，没有任何变化，我的磁盘阵列是dell3620f，服务器是sun的2900和890，你看一下/kernel/drv/scsi_vhci.conf 我配的对吗？
@zhbzcy
"SUN SENA", "symmetric-option";
在原来的文件中这一行，SUN是vender ID，从第一个字母到SENA的第一个字母我记得是8个字符，不足8位用空格补足， 后面ProductID有多长写多长。
也就是
"DELL MD36xxf", "symmetric-option";
这个格式中，DELL后面应该有4个空格，具体按照原来文件中的示例写。
然后确保在/kernel/drv/fp.conf中mpxio是处于打开的状态，看对需要启用mpxio的HBA卡的路径是否写进去了，然后stmsboot -u 使其生效。
我惊呆了，好贴啊，很难得的好贴
搞定了，谢谢！！
