Dell PowerVault ME5 Series Storage System CLI Reference Guide

There are two sources of user credentials for the storage system:

• The primary source is local users created by using the create user command.
• The secondary source is an LDAP server.

Users logging in using their LDAP credentials must authenticate using these credentials and be members of a group that is authorized to access the storage system. The group will exist on the LDAP server and will be listed under the Member Of property for the user account. The same group name must also exist in the storage system, and be created by using the create user-group command.

Individual user preferences are not saved in the storage system. Any settings made to the login session are not retained after the session terminates. If the user wants to retain any preferences for the session, these must be saved as part of the user group. Any changes made to a user group will affect all members of that group.

The system supports a maximum of 5 user groups to allow different permissions and user preferences. User group permissions are defined by assigning roles, the same as for local users. User group preference parameters include the storage size base, precision, and units; temperature scale; and timeout.

Local users and LDAP users can use the same set of CLI commands. Only LDAP users with the manage role can create, modify, and delete both local users and LDAP user groups.

For more information about the LDAP feature, see the Dell PowerVault ME5 Series Administrator's Guide.

Optional. Sets the base for entry and display of storage-space sizes:

• 2: Sizes are shown as powers of 2, using 1024 as a divisor for each magnitude. In base 2 when you set a size, whether you specify a base-2 or base-10 size unit, the resulting size will be in base 2.
• 10: Sizes are shown as powers of 10, using 1000 as a divisor for each magnitude. In base 10 when you set a size, the resulting size will be in the specified unit. This option is the default.

Operating systems usually show volume size in base 2. Disk drives usually show size in base 10. Memory (RAM and ROM) size is always shown in base 2.

Optional. Specifies the interfaces that the user group can access. Multiple values must be separated by commas and no spaces.

• cli: Command-line interface. This is enabled by default.
• wbi: Web-browser interface (the PowerVault Manager). This is enabled by default.
• ftp: SFTP interface.
• none: No interfaces.

Only secure protocols are supported for the above interfaces. To enable or disable interface protocols, use the set protocols command.

Optional. Sets the number of decimal places from 1 to 10 for display of storage-space sizes.

Optional. Specifies the user group role as one or more of the following values:

• monitor: User group can view but not change system settings. This is the default.
• standard: User group can view and change system settings except: configuring local users; configuring LDAP; performing write operations through SFTP; performing file uploads from the PowerVault Manager; using the restore defaults command.
• manage: User group can view and change system settings.
• diagnostic: For use by or with direction from technical support.

Multiple values must be separated with a comma (with no spaces). If multiple values are specified, the user group's access to commands will be determined by the highest role specified.

Optional. Alias for base.

Optional. Alias for precision.

Optional. Alias for units.

Optional. Sets the scale for display of temperature values:

• Fahrenheit or f: Temperatures are shown in degrees Fahrenheit.
• celsius or c: Temperatures are shown in degrees Celsius. This is the default.

Optional. Sets the timeout value in seconds for the login session. Valid values are 120–43200 seconds (2–720 minutes). The default is 1800 seconds (30 minutes).

Optional. Identifies the user group type.

Optional. Sets the unit for display of storage-space sizes:

• auto: Sizes are shown in units determined by the system. This is the default.
• MB: Sizes are shown in megabytes.
• GB: Sizes are shown in gigabytes.
• TB: Sizes are shown in terabytes.

Based on the precision setting, if a size is too small to meaningfully display in the selected unit, the system uses a smaller unit for that size. For example, if units is set to TB, precision is set to 1, and base is set to 10, the size 0.11709 TB is instead shown as 117.1 GB.

A name for the new user group, which must match the name used in the LDAP database including capitalization. Input rules:

• The value is case sensitive.
• The value can have a maximum of 29 bytes.
• The value can include printable UTF-8 characters except a spare or: " , < \ :
• A value that includes a space must be enclosed in double quotes.
