第一步：重新配置光纤通道,结果提示部分成功
Cfgadm –c configure c8
Cfgadm –c configure c9
截图没法发出来，这两个命令虽然提示部分成功，但是cfgadm -al 显示已配置，而且format也能够看到共享磁盘，如下：
c8 fc-fabric connected configured unknown
c8::200600a0b81f71b4 disk connected configured unknown
c8::210100e08ba7607a unknown connected unconfigured unknown
c9 fc-fabric connected configured unknown
c9::200700a0b81f71b4 disk connected configured unknown
c9::210000e08b87607a unknown connected unconfigured unknown
c9::500308c146699004 tape connected configured unknown
c9::500308c146699007 tape connected configured unknown
Format也可以看到磁盘：

但是执行scdpm -p all 显示 disk-path依然Fail

hrsms01:/dev/did/rdsk/d1 Ok
hrsms01:/dev/did/rdsk/d2 Ok
hrsms01:/dev/did/rdsk/d4 Fail

第二步：验证能否访问共享磁盘，能够访问Global Device，选取（hrsms01:/dev/did/rdsk/d4）进行验证
共享磁盘路径与Global Device的路径映射如下：
scdidadm -L

访问磁盘路径，成功

而访问对应的Global Device，却提示失败,在hrsms02上，确实可以的
hrsms01>#prtvtoc /dev/did/rdsk/d4s2
prtvtoc: /dev/did/rdsk/d4s2: No such device or address

0 4 00 12288 104837120 104849407
7 4 01 0 12288 12287
从上述分析来看，Global Device的配置应该是存在问题的
总结下：目前存在的问题就是
Hrsms01能够识别到共享磁盘，能够访问共享磁盘，但依然无法访问Global Device（CLUSTER切换的必备条件）
请问诸位，重新配置Global Device 有没有风险，各位的建议又是什么？谢谢！
艾特东方蜘蛛 哇。。。
scdidadm -C
scdidadm -r
scgdevs
通过上面命令重新识别一下did设备 SUN 服务器搞个IBM的盘阵，你说说，IBM的盘阵经常出问题！ byuq 朋友，谢谢你的帮助！
还是想问下
scdidadm -C
scdidadm -r
scgdevs
执行有没有风险？这个系统对客户比较重要，原谅我的谨慎！
我本来打算只执行 scgdevs或者 scdidadm -r; scgdevs 试下的，
非常感谢！
