适用场景

  • ONTAP 8.2 C 模式
  • ONTAP 8.3
  • ONTAP 9.x
  • iSCSI SAN
  • FCP SAN
  • SnapDrive for Windows ( SDW ) 7.1.x
  • 适用于 Windows 的 SnapCenter 插件( SCW ) 4.x

问题描述

SnapDrive for Windows 拒绝将 LUN 大小增加到超过给定大小。

ONTAP lun resize 命令失败,并显示错误,指出已达到最大大小。

限制取决于 ONTAP 版本:

  • 在 ONTAP 9.4 及更早版本中、您只能将 LUN 扩展到原始大小的大约 10 倍、但不能超过 16 TB 。
  • 在 ONTAP 9.5 中、无论 LUN 的原始大小如何、您都可以将其扩展到 16 TB 。
  • 在ONTAP 9.8及更高版本中、您可以将ASA配置中的LUN扩展到128 TB。
  • 在ONTAP 9.12.1P2及更高版本中、您可以在AFF、FAS和ASA配置中将LUN增长到128 TB。

警告: 由于 Solaris LUN 的分区方案,无法调整其大小。
