如何禁用多路径

在基于 SPARC 或 x86 的系统上，执行以下步骤在所有具有多路径功能的设备上禁用多路径。如果您只想在特定的 FC 或 SAS HBA 端口上禁用多路径，请参阅基于每端口启用或禁用多路径。

1. 禁用设备多路径。

   # stmsboot -d
   WARNING: stmsboot operates on each supported multipath-capable controller
            	detected in a host. In your system, these controllers are
   
   	/devices/pci@780/pci@0/pci@8/SUNW,qlc@0/fp@0,0
   	/devices/pci@780/pci@0/pci@8/SUNW,qlc@0,1/fp@0,0
   	/devices/pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@1
   	/devices/pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@1
   	/devices/pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2
   	/devices/pci@7c0/pci@0/pci@9/LSILogic,sas@0
   	/devices/pci@7c0/pci@0/pci@9/LSILogic,sas@0
   
   	If you do NOT wish to operate on these controllers, please quit stmsboot
   	and re-invoke with -D { fp | mpt } to specify which controllers you wish
   	to modify your multipathing configuration for.
   
   	Do you wish to continue? [y/n] (default: y) y
   	Checking mpxio status for driver fp
   	Checking mpxio status for driver mpt
   	WARNING: This operation will require a reboot.
   	Do you want to continue ? [y/n] (default: y) y
   	The changes will come into effect after rebooting the system.
   	Reboot the system now ? [y/n] (default: y) y

   注 - 在重新引导期间，/etc/vfstab 和转储配置将更新，以反映设备名称更改。

2. (u53ef选)重新引导之后，如有必要，按多路径注意事项中的“设备名称更改注意事项”所述，将您的应用程序配置为使用新的设备名称。
