3.4.4.1 示例-从磁盘设备组 (SDS) 移除节点
以下示例显示从磁盘设备组（元集）移除主机名，并检验节点是否已从磁盘设备组中移除。虽然示例显示的是从单个磁盘设备组移除节点，但一个节点可同时属于不止一个磁盘设备组。对于每个您想从中移除该节点的磁盘设备组，请重复使用 metaset 命令。
[Determine the disk device group(s) for the node:]
# scstat -D
-- Device Group Servers --
Device Group Primary Secondary
------------ ------- ---------
Device group servers: dg-schost-1 phys-schost-1 phys-schost-2
[Become superuser.]
[Remove the hostname from all disk device groups:]
# metaset -s dg-schost-1 -d -f -h phys-schost-2
[Verify removal of the node:]
# scstat -D
-- Device Group Servers --
Device Group Primary Secondary
------------ ------- ---------
Device group servers: dg-schost-1 phys-schost-1 -
