VMAX 查看Thin Pool命令实例

VMAX 查看Thin Pool命令实例

介绍

用户部署VMAX Virtual Provisioning（虚拟调配）功能之后，需要对阵列内的Thin Device和Thin Pool进行管理。本文介绍了几个管理Thin Pool的常用的Solution Enabler命令来查看Thin Pool的状态，方便存储管理员日常的阵列维护操作。

查看Thin Pool中的信息:

用户可以使用smycfg命令显示Thin Pool的相关信息本文中介绍三条命令:

1. 显示当前阵列中所有Thin Pool的信息，使用下列命令：

symcfg list –pool –thin

下列命令输出中可以可以看到，该阵列中存在两个Thin Pool，名字分别为xxx_thinpl0和xxx_thinpl1，pool中包含2-Way-Mir的磁盘（Raid0），以xxx_thinpl0为例，该pool大小为150240 Track（64k），即9390MB，其中已经使用了672 Track（64k），即42MB的空间。

2. 用户可以进一步使用命令查看单个Thin Pool中的详细信息：

symcfg show -pool -thin –detail

输入命令查看xxx_thinpl0，-sid xxx为Symmetrix阵列的序列号：

symcfg show -pool xxx_thinpl0 -thin -detail -sid xxx

在该命令输出中，除了可以看到thin pool的属性外，还可以显示该Pool中所绑定的Thin Device 和Data Device。可以看到xxx_thinpl0中有四个Thin Device（2093：2096），总的主机可见601020 Track，和一个Data Device（20A0）实际存放数据，且处于启用状态。

3. 同样，使用用户也可以使用以下命令显示特定的Thin Device。

symcfg list -tdev -RANGE firstvol:lastvol

以当前Symmetrix阵列中的为例，输入命令，查看2093:2096这个区域的Thin Device。symcfg list -tdev -range 2093:2096 -sidxxx

命令输出中也可以看到2093:2096这四个Thin Device的可用容量（Total Tracks），Thin Device 占用的Data Device的百分比（Pool Subs）等。
