Command Description

Command Description

After installing the driver, you can use the hioadm tool to manage and configure the ES3000 V3. This chapter describes the hioadm command. The command output varies according to the actual operation result.

hioadm Tool

hioadm is an ES3000 V3 management tool. Its command format is as follows:

hioadm <major cmd> <minor cmd1> <parameter1> <minor cmd2> <parameter2> ...

<major cmd> can be any of the following:

  • info: information query
  • format: formatting
  • secure: secure erasure of data
  • updatefw: firmware upgrade management
  • capacity: capacity management
  • log: device log management
  • powerstate: power consumption management
  • temperature: temperature management
  • writemode: write mode management
  • selftest: diagnosis result query
  • label: electronic label query
  • namespace: namespace management
  • recovery: data recovery
  • loadhist: historical load query
Target devices are SSDs (SSD controllers) and logical disks. The -d subcommand is used to specify the target device. For example, nvme0 indicates a PCIe SSD, and nvme0n1 indicates a logical disk. Currently only the info and format commands support both SSDs and logical disks. Other commands support only SSDs (if nvme0n1 is entered, it is regarded as nvme0.)

Operation Logs

All setting operations performed on the ES3000 V3 by using the hioadm tool are recorded. The log file location is as follows:
  • For Linux, /opt/hio/operationLogs/operations.log.
  • For Windows, .\operationLogs\operations.log in the installation directory.
  • For ESXi, /scratch/hio/operationLogs/operations.log.

If the log file size exceeds 4 MB, the file is automatically backed up as an operations.log.old file, overwriting the existing operations.log.old file.

The log file content includes the command start time, remote client IP address, user name, command, command output time, and operation result.

The operation result is one of the following:

  • SUCCEEDED: The command was successfully executed.
  • FAILED: The command failed to be executed.
  • CANCELED: The command was canceled because the user selected No when asked for conformation.
  • KILLED: The command was stopped abnormally. For example, the user performed a Ctrl+C operation, closed the client, killed the process, or restarted the OS.

The following is an operation log in Linux:

[2016-01-27 17:37:10] [root@] [hioadm updatefw -d nvme0 -s 3 -a 1] [17:37:15] [SUCCESSED].
