SAN环境中配置SSO时的一点经验！
环境：NBU4.5FP3. HPUX11.11. L20/700带库*2.SAN
在master server上扫描设备：

红色字体与黑色字体分别是两个带库中的各自8个drive.
其中，红色字体的drive在2年前已经配置完成，并且正常工做。昨天配置另外一个带库，在配置sso时如下：
| drvie number in robot | path |
| 1 | /dev/rmt/78mnb |
| 2 | /dev/rmt/79mnb |
| 3 | /dev/rmt/80mnb |
| 4 | /dev/rmt/81mnb |
| 5 | /dev/rmt/82mnb |
| 6 | /dev/rmt/83mnb |
| 7 | /dev/rmt/84mnb |
| 8 | /dev/rmt/85mnb |
配置完成后，起inlinecopy的policy,storage unit分别指向两个带库，这时发现新配置的带库drive只要磁带放到drive里面就会down掉！报Request terminated because media is unavailable in DOWN drive
后来经高人指点重新配置sso.如下：
| drvie number in robot | path | H/W PATH |
| 1 | /dev/rmt/78mnb | 0/8/0/0.3.8.255.0.0.0 |
| 2 | /dev/rmt/82mnb | 0/8/0/0.3.8.255.0.0.1 |
| 3 | /dev/rmt/79mnb | 0/8/0/0.3.9.255.0.0.0 |
| 4 | /dev/rmt/83mnb | 0/8/0/0.3.9.255.0.0.1 |
| 5 | /dev/rmt/80mnb | 0/10/0/0.2.8.255.0.0.0 |
| 6 | /dev/rmt/85mnb | 0/10/0/0.2.8.255.0.0.2 |
| 7 | /dev/rmt/81mnb | 0/10/0/0.2.9.255.0.0.0 |
| 8 | /dev/rmt/84mnb | 0/10/0/0.2.9.255.0.0.1 |
也就是NBU中DRIVE的顺序要按照H/W PATH来设定，而不是设备文件名字！结果一切正常！
现在还有不明白NBU中如何使用设备为何要看H/W PATH ??
