System

Overview

This function displays the system information and a list of users who are currently logged in.

Caution

  • If the message "Currently Network Configuration is set to factory default." is displayed, the network environment settings for the MNT port must be performed. Use the [Setup Network Environment] function in the [Network] screen under the [System] navigation. Some functions are not available if the network environment settings are incomplete.

  • If the message "Configuration was applied to storage system." is displayed in the system message field, the storage system must be rebooted. Any setting processes cannot be performed until the applied configuration information is enabled by rebooting the storage system.

  • The following login users are displayed:

    • Users who logged in to the Master CM via Web GUI

    • Users who logged in to the Slave CM via Web GUI

    • Users who logged in to the Master CM via CLI or other software

      (Users who are logged in to the Slave CM from CLI or other software are not displayed.)

    • Users who logged in to the Master CM via RESTful API

Note

  • If the system message "Unified storage license has been registered." is displayed, the unified upgrade must be performed. Use the [Apply Controller Firmware] function in the [Firmware Maintenance] screen under the [System] navigation and reboot the storage system. After changing the firmware for the active controller to the unified firmware (*1), apply the same unified firmware to the inactive controller. Refer to the [Apply Controller Firmware] function for details.

    *1  :  A controller firmware with built-in Unified Storage functions.

  • The storage system name is displayed at the top of the [System] navigation category.

    The "Storage System Name" is specified using the [Modify Storage System Name] function. Refer to the [Modify Storage System Name] function for details.

Deduplication/Compression

Whether Deduplication/Compression for the storage system is enabled or disabled is displayed.

This function is supported in the ETERNUS DX200 S5, the ETERNUS DX500 S5/DX600 S5/DX900 S5, the ETERNUS DX8900 S4, and the ETERNUS AF250 S3/AF650 S3. The ETERNUS DX8900 S4 supports Compression only.

Storage Cluster

If a license for the Storage Cluster function has already been registered, "Enable" is displayed. If the license is not registered, "Disable" is displayed.

If this item is enabled, the total TFOV capacity per storage system (or the total capacity of volumes that are used for the Storage Cluster function in a storage system) is displayed in the "Enable (total TFOV capacity)" format.

Note that Web GUI cannot be used to register a Storage Cluster license or to change the total TFOV capacity. To register the license, use ETERNUS SF Storage Cruiser. To change the total TFOV capacity, use CLI or ETERNUS SF Storage Cruiser (*1).

For the ETERNUS DX60 S5, this item is not displayed.

When the total TFOV capacity is expanded from the default capacity, the shared area in the cache memory is used. The default capacity of each model is as follows:

  • For the ETERNUS DX100 S5: 256 TB

  • For the ETERNUS DX200 S5: 256 TB

  • For the ETERNUS DX500 S5: 384 TB

Login User

Up to 96 sessions of user information for users who are logged in to the storage system from Web GUI, CLI, RESTful API, or SOFT (other software) are displayed in a list. The following shows the maximum number of sessions for each interface.

  • Web GUI: Up to 16 sessions

  • CLI (including SOFT): Up to 16 sessions

  • Total number of sessions for RESTful API and Easy Administration View: Up to 64 sessions

For Web GUI, the users who are logged in to both the Master CM and Slave CM are displayed. For CLI, RESTful API, or SOFT (other software), the users who are logged in to the Master CM are displayed. Login user information is sorted according to interface (GUI → CLI → SOFT → REST), login date (ascending order), and session IDs (ascending order).

Item Description

Interface

The interface type for users who are logged in is displayed.

  • GUI

    The user logged in via Web GUI (Normal View).

    Otherwise, the user logged in via Web GUI (Normal View) from the AIS Connect server.

  • GUI2

    The user logged in via Web GUI (Easy Administration View).

    Otherwise, the user logged in via Web GUI (Easy Administration View) from the AIS Connect server.

  • CLI

    The user logged in via CLI.

    Otherwise, the user logged in via CLI from the AIS Connect server.

  • SOFT

    The user logged in via software.

    "SOFT" is displayed for users in the following conditions:

    • Logged in from software with the default "Software" role via CLI

    • Logged in using SMI-S via software

    • Logged in from software using Dynamic LUN Mirroring (DLM) via CLI

    • Logged in using RESTful API JOB Agent (RJA) via RESTful API

  • REST

    The user logged in via RESTful API.

Session ID

An identification number (0 to 1999999) for users who are logged in is displayed.

A session ID is obtained for each login and released with each logout. Because the session ID is obtained discretely, the same session ID is not used even if the same user logs in again.

The following shows the range of session IDs to be used.

  • Web GUI (Normal View): 1 - 999
  • CLI (including when the interface is "SOFT"): 10001 - 33999
  • RESTful API and Easy Administration View: 1000001 - 1999999

In a Unified Storage environment, Web GUI uses session IDs from 10001 onwards for internal processes in the same way as CLI. An "*" (asterisk) is added on top of the current user's (your) session ID.

User ID

The user name (user ID) for a user who is logged in is displayed. When the interface is "SOFT" (SMI-S/DLM/RJA [RESTful API JOB Agent]), the field is blank. The field is also blank for internal process sessions of Web GUI in a Unified Storage environment.

Role

The user role for a user who is logged in is displayed. A "-" (hyphen) is displayed for internal process sessions of Web GUI in a Unified Storage environment.

Note that multiple users cannot update data that is managed by the storage system at the same time. The storage system is exclusively used by a user who is updating the data. The exclusion is released when the updating is complete.

IP Address

The IP address for a user who is logged in is displayed. If an AIS Connect server is used to log in, "AIS Connect Server" is displayed. When the interface is "SOFT" (SMI-S/DLM/RJA [RESTful API JOB Agent]), the field is blank. The field is also blank for internal process sessions of Web GUI in a Unified Storage environment.
