Please keep this is in mind when dealing with your storage devices and MPIO code .

在处理存储设备和MPIO代码时，要谨记这一点。

MPIO can be used to facilitate fail-over or load balancing .

MPIO能用于简化故障跳过或负载平衡。

Storage vendors will present MPIO disk differently .

存储供应商将会区别地呈现MPIO磁盘。

Ensure that MPIO for the disks is configured and functioning appropriately .

Both PCMs allow for any MPIO device to be used as a paging device and a dump device .

两个PCM都支持任何MPIO设备作为分页设备和转储设备使用。

The final component to install ( and update ) is the multipath I / O ( MPIO ) device driver .

要安装（和更新）的最后一个组件是多路径I/O（MPIO）设备驱动程序。

All the prerequisites and restrictions that are listed in the previous sections are applicable for the MPIO scenario .

前面列出的所有前提条件和限制也适用于MPIO场景。

Historically , SDD configured vpath devices to provide MPIO to hdisk devices .

通常，SDD配置了vpath设备来将MPIO提供给hdisk设备。

Multi-path I / O ( MPIO ) helps provide increased availability of virtual SCSI resources by providing redundant paths to the same resource ( disk ) .

Multi-pathI/O（MPIO）为相同的资源（磁盘）提供冗余的路径，有助于提高虚拟SCSI资源的可用性。

You should also make sure that the device drivers support multi-path I / O ( MPIO ), which allows for load balancing and availability of your I / O subsystem .

还应该确保设备驱动程序支持多路径I/O（MPIO），它支持I/O子系统的负载平衡和可用性。

The AIX and VIOS default MPIO ( AIXPCM ) is provided as an integrated part of the base VIOS POWERVM firmware and AIX operating system product distribution .

AIX和VIOS默认MPIO（AIXPCM）只作为基础VIOSPOWERVM固件和AIX操作系统产品的一个集成部分提供。

Redundant HBAs on each DB2 member and the use of multipath software , such as IBM AIX MPIO , or device drivers that support multipath access to LUNS is recommended .

建议在每个DB2成员上使用冗余HBAs，使用多路径软件（比如IBMAIXMPIO），或者支持LUNS多路径访问的设备驱动器。

If you are migrating from IBM to IBM storage , then it is likely that you will simply need to update the MPIO code , FC adapter firmware and supporting device drivers .

如果您是从IBM存储迁移到IBM存储，那么您可能只需要更新此MPIO代码、FC适配器固件以及设备驱动器。

A more efficient solution is to create two VIO Servers , place one SAN-attached I / O card in each , and then configure multipath I / O ( MPIO ) on the LPARs that need access to the SAN .

一种更有效的解决方案是创建两个VIO服务器，每个服务器中放置一个连接到SAN的I/O卡，然后在需要访问SAN的LPAR中配置多路径I/O（MPIO）。
