Oracle Solaris 11.1 管理:SAN 配置和多路径 Oracle Solaris 11.1 Information Library (简体中文) |
使用 mpathadm 命令确定和配置 Solaris OS 多路径支持。mpathadm 命令通过 ANSI 标准多路径管理 API 启用多路径管理。本章中用来表示路径、启动器端口、目标端口和 LU 的术语与 T10 规范一致。
执行以下任务来管理多路径设备。
可以使用 mpathadm 命令显示多路径支持信息并管理多路径搜索。多路径支持和属性信息用多路径管理 API 插件库名称进行标识,可使用 mpathadm 命令显示该插件库名称。
# mpathadm list mpath-support mpath-support: libmpscsi_vhci.so
# mpathadm show mpath-support libmpscsi_vhci.so mpath-support: libmpscsi_vhci.so Vendor: Sun Microsystems Driver Name: scsi_vhci Default Load Balance: round-robin Supported Load Balance Types: round-robin logical-block Allows To Activate Target Port Group Access: yes Allows Path Override: no Supported Auto Failback Config: yes Auto Failback: on Failback Polling Rate (current/max): 0/0 Supported Auto Probing Config: 0 Auto Probing: NA Probing Polling Rate (current/max): NA/NA Supported Devices: Vendor: SUN Product: T300 Revision: Supported Load Balance Types: round-robin Vendor: SUN Product: T4 Revision: Supported Load Balance Types: round-robin . . .
命令输出还会显示多路径支持软件支持的设备产品的列表。缺省情况下,多路径支持 libmpscsi_vhci.so 库文件支持符合 T10 目标端口组的设备。
以下步骤描述如何显示启动器端口的属性。
# mpathadm list initiator-port Initiator Port: iqn.1986-03.com.sun:01:ffffffffffff.4e94f9bd,4000002a00ff Initiator Port: 210100e08ba41feb Initiator Port: 210000e08b841feb
# mpathadm show initiator-port 2000000173018713 Initiator Port: 210100e08ba41feb Transport Type: Fibre Channel OS Device File: /devices/pci@1,0/pci1022,7450@1/pci1077,141@2,1/fp@0,0
使用 mpathadm 命令显示 LU 列表以及每个 LU 的属性。显示的 LU 列表中又包含可用于显示特定 LU 的属性的名称。

对称设备可以自动故障恢复到可能的最优路径。如果在初始路径上发生了故障转移,则备用路径将成为新的联机路径。通常,备用路径不是最理想的路径。当启用自动故障恢复时,初始路径会重新联机,并自动故障转移到初始路径。

注 - 当系统正在运行时,mpathadm modify 命令设置所启动的自动显示有效。但是,要保持更改的设置持久,必须更新 /etc/driver/drv/scsi_vhci.conf 文件。请参阅配置自动故障恢复。
此操作仅适用于以下两个类别的设备:
具有由多路径支持可识别和支持的专用故障转移机制的非对称设备
符合 T10 标准目标端口组支持 libmpscsi_vhci.so 并提供了显式模式非对称 LU 访问的设备
