solution

  1. OK whether the tested disk is grouped as RAID1. Use raidstat in the View or View Model – R 12-disk Model (such as aServer-R-2105) Default System Disk group RAID1.
  2. Use the command in the background: dd if=/dev/zero of=/sf/date/local/velocity_test bs=4k count=40000 oflag=direct to test whether the performance is lower than 20M/S.
  3. There is an OS partition in System Disk, which will affect the performance. The disks in RAID 1 need to synchronize the data of the primary disk to the secondary disk, which will reduce the performance. Ignore this Alerting.
    Cause:
    The inspection tool has a problem. This command is not Applied to User/Group write performance Test Connectivity of the RAID 1 System Disk. Ignore this Alerting and synchronize it later when a suitable command is available.
