适用于

  • E 系列控制器固件 8.xx
  • SANtricity

说明

从 E 系列控制器固件版本 08.25 M1 (预计 2016 年 5 月)开始,支持用于精简卷的 SCSI 命令( SCSI 操作代码 42H ) UNMAP 。如果您要从以前的控制器固件版本(包括 08.25.04.00 )升级、在UNMAP对精简卷进行手动更改之前、现有的精简卷将不会在升级后自动支持。  

UNMAP所选操作系统中启用对精简卷的支持需要执行一些额外的步骤。本文档将详细介绍 VMware ESXi 操作系统的步骤。

注:对于 VMware ESXi ,只有在其上具有 VMFS-2 或 VMFS-3 数据存储库的精简卷才能直接支持UNMAP从 VMware ESXi 主机执行的操作。如果将精简卷直接用于物理原始设备映射( PRDM )或虚拟原始设备映射( VRDM )到虚拟机,请按照该虚拟机上安装的操作系统的 UNMAP 知识库文章执行操作。
