适用场景

  • ONTAP Select
  • 容量许可证
  • 磁盘分区(分区)
  • 非零RAID配置

问题解答

  • 使用license show-status -license select 命令查看有关当前容量许可证使用情况的信息
  • 使用storage disk partition show 命令查看有关磁盘分区的信息
  • 分区usable-size (不包括奇偶校验分区)之和是license show-status 命令中显示的容量许可证
  • 例如:
ontapselect::*> license show-status -license select
(system license show-status)
Status      License      Scope      Detailed
---------   --------   -------     ---------
valid      Select      node      ontapselect-01: Currently using 3.5TB. System may use up to 7TB.
 
storage disk partition show -fields container-name,position,usable-size,disk-type
partition       container-name        position   usable-size  disk-type
----------      ----------------      --------    -----------  ---------
NET-1.1.P1      /aggr1/plex1/rg0      data        700GB        SSD
NET-1.2.P1      /aggr1/plex1/rg0      data      700GB        SSD
NET-1.3.P1      /aggr1/plex1/rg0      dparity     700GB        SSD
NET-1.5.P1      /aggr1/plex1/rg0      parity     700GB        SSD
NET-1.6.P1      /aggr1/plex1/rg0      data      700GB        SSD
NET-1.7.P1      /aggr1/plex1/rg0      data      700GB        SSD
NET-1.8.P1      /aggr1/plex1/rg0      data      700GB        SSD
  • 在上面的示例中、我们有2个奇偶校验磁盘和5个700 GB的数据磁盘、即3.5 TB、因此、许可证的计算公式为:Currently using 3.5TB.
  • 虽然在计算许可使用量时不会考虑奇偶校 验磁盘、但   根据许可证使用量计算WAFL、Snapshot和高级区域校验和(偶校验和、ZCS)开销。
    • 这意味着、除了 所需的可用许可证需要计算大约16.5%的开销。 
      • WAFL开销为~10%+ 聚合快照为~5%+ AZCS 开销为1.5% 
注意:计算分区可能会得到大约数量的许可证容量、而不是一个统一的容量。
