适用于

  • OnCommand Insight ( OCI ) 7.3.9 SP7
  • HPE 3PAR 数据源

解答

对具有可用 chunklet 的存储池的总容量运行查询时, "capacity - total ( GB ) " 属性可能会显示零和非零值,如下所示。

查询结果基于每个阵列的 "showspace" 输出。在上述示例中, OCI 已确定前两个阵列使用 RAID 6 ,因为非管理卷位于 RAID 6 通用配置组( CPG )上。因此, OnCommand Insight ( OCI )将通过运行以下命令查询此类池的可用空间:

showspace -t r6 -p -devtype SSD

如果响应返回 0 GB 的可用空间,则总容量也将在 OCI 中列为零。 

<STANDART_OUT>
--Estimated(MB)---,
RawFree,UsableFree
0,0

相反,最后两个存储池使用 RAID 10 ,恰好是新设置。如果阵列只有管理卷, OCI 会将可用的 chunklet 池视为 RAID 10 ,因为admin.usr记录 RAID 组的可能性最大的是 RAID 10 。阵列上唯一的 CPG 尚未用尽任何容量。
