示例—更改所需的辅助节点数

以下示例显示了 scsetup 配置设备组 (dg-schost-1) 所需的辅助节点数时生成的 scconf 命令。 此示例假定磁盘组和卷为以前创建的磁盘组和卷。


# scconf -c -D name=phys-host-1,nodelist=phys-schost-1:phys-schost-2,phys-schost-3\
preferenced=true,failback=enabled,numsecondaries=1

# scconf -p | grep Device
Device group name:                             dg-schost-1
   Device group type:                          SDS/SVM
   Device group failback enabled:              yes
   Device group node list:                     phys-schost-1, phys-scost-2, phys-schost-3 
   Device group ordered node list:             yes
   Device group desired number of secondaries: 1
   Device group diskset name:                  dg-schost-1

以下示例显示如何使用空字符串值配置缺省的辅助节点数。 设备组将配置为使用该缺省值,即使缺省值改变。


# scconf -c -D 
name=diskgrp1, nodelist=host1:host2:host3,
preferenced=false,failback=enabled,numsecondaries=
 # scconf -p | grep Device
Device group name:                             dg-schost-1
   Device group type:                          SDS/SVM
   Device group failback enabled:              yes
   Device group node list:                     phys-schost-1, phost-2, phys-schost-3
   Device group ordered node list:             yes
   Device group desired number of secondaries: 1
   Device group diskset name:                  dg-schost-1
