4.2.4. 黑​​​​​​​名​​​​​​​单​​​​​​​之​​​​​​​外​​​​​​​的​​​​​​​设​​​​​​​备​​​​​​​

You can use the blacklist_exceptions section of the configuration file to enable multipathing on devices that have been blacklisted by default. For example, by default, devices with vendor = "IBM" and product = "S/390.*" are blacklisted since usually DASD devices are used for local storage. If you do need to enable multipathing on these devices, uncomment the following lines in the configuration file:

blacklist_exceptions {
       device {
               vendor  "IBM"
               product "S/390.*"
       }
}

当​​​​​​​在​​​​​​​配​​​​​​​置​​​​​​​文​​​​​​​件​​​​​​​的​​​​​​​ blacklist_exceptions 指​​​​​​​定​​​​​​​设​​​​​​​备​​​​​​​时​​​​​​​，您​​​​​​​必​​​​​​​须​​​​​​​以​​​​​​​指​​​​​​​定​​​​​​​黑​​​​​​​名​​​​​​​单​​​​​​​的​​​​​​​相​​​​​​​同​​​​​​​方​​​​​​​法​​​​​​​来​​​​​​​指​​​​​​​定​​​​​​​例​​​​​​​外​​​​​​​情​​​​​​​况​​​​​​​。​​​​​​​例​​​​​​​如​​​​​​​：在​​​​​​​ devnode 黑​​​​​​​名​​​​​​​单​​​​​​​条​​​​​​​目​​​​​​​中​​​​​​​指​​​​​​​定​​​​​​​的​​​​​​​设​​​​​​​备​​​​​​​无​​​​​​​法​​​​​​​使​​​​​​​用​​​​​​​ WWID 将​​​​​​​其​​​​​​​指​​​​​​​定​​​​​​​为​​​​​​​例​​​​​​​外​​​​​​​情​​​​​​​况​​​​​​​，即​​​​​​​使​​​​​​​列​​​​​​​入​​​​​​​黑​​​​​​​名​​​​​​​单​​​​​​​的​​​​​​​设​​​​​​​备​​​​​​​和​​​​​​​该​​​​​​​ WWID 关​​​​​​​联​​​​​​​也​​​​​​​不​​​​​​​行​​​​​​​。​​​​​​​同​​​​​​​样​​​​​​​，devnode 例​​​​​​​外​​​​​​​也​​​​​​​只​​​​​​​适​​​​​​​用​​​​​​​于​​​​​​​ devnode 条​​​​​​​目​​​​​​​，而​​​​​​​ device 例​​​​​​​外​​​​​​​只​​​​​​​适​​​​​​​用​​​​​​​于​​​​​​​ device 条​​​​​​​目​​​​​​​。​​​​​​​
