确定本地层(聚合)的驱动器和RAID组信息

贡献者

某些本地层(聚合)管理任务要求您了解构成本地层的驱动器类型、驱动器大小、校验和和状态、是否与其他本地层共享以及RAID组的大小和构成。

步骤
  1. 按 RAID 组显示聚合的驱动器:

    storage aggregate show-status aggr_name

    此时将显示聚合中每个 RAID 组的驱动器。

    您可以在中查看驱动器的RAID类型(数据、奇偶校验、dparity) Position 列。如果 Position 列显示 shared,则驱动器为共享驱动器:如果是HDD,则为分区磁盘;如果是SSD,则为存储池的一部分。

cluster1::> storage aggregate show-status nodeA_fp_1

Owner Node: cluster1-a
 Aggregate: nodeA_fp_1 (online, mixed_raid_type, hybrid) (block checksums)
  Plex: /nodeA_fp_1/plex0 (online, normal, active, pool0)
   RAID Group /nodeA_fp_1/plex0/rg0 (normal, block checksums, raid_dp)
