Data types and value ranges

The maximum length of any single parameter entered into the command line is 2176 bytes.

Note: When creating a new object, the clustered system (system) assigns a default -type name if one is not specified. The default -type name consists of the object prefix and the lowest available integer starting from 0 (except for nodes starting from 1); for example, vdisk23; the default -type name must be unique.

Data types lists the data types and the value ranges for each.

Table 1. Data types
Data types	Value ranges
`filename_arg`	This is a (optionally fully qualified) file name, containing a maximum of 169 characters. Valid characters are: . (period; the field must not start with, end with, or contain two consecutive periods) / (forward slash) - (hyphen) _ (underscore) a–z (lowercase letters, A through Z) A–Z (uppercase letters, A through Z) 0–9 (numerals 0 through 9)
`directory_or_file_filter`	Specifies a directory, file name filter, or both, within the specified directory. Valid directory values are: /dumps /dumps/audit /dumps/configs /dumps/elogs /dumps/feature /dumps/iostats /dumps/iotrace /dumps/software The file name filter can be any valid file name, containing a maximum of 128 characters, with or without the "" (wildcard), and appended to the end of a directory value. Valid characters are: (asterisk/wildcard) . (the field must not start with, end with, or contain two consecutive periods) / - _ a–z A–Z 0–9
`filename_prefix`	The prefix of a file name, containing a maximum of 128 characters. Valid characters are: - _ a–z A–Z 0–9
`name_arg`	Names can be specified or changed using the create and modify functions. The view commands provide the name and ID of an object. Note: The system name is set when the system is created. The first character of a `name_arg` must be nonnumeric. The first character of an object name cannot be a `–` (dash) because the CLI (command-line interface) interprets it as being the next parameter. Valid characters are: `.` (a period - the field must not start with, end with, or contain two consecutive periods) `/` `-` `_` space `a` through `z` `A` through `Z` `0` through `9`
`password`	This is a user-defined password containing a maximum of 15 characters. Valid characters are: - (cannot be used as the first character) _ a–z A–Z 0–9
`serial_number`	The serial number is 7 digits, the first two of which define the manufacturing location, leaving 5 digits for the product.
`ip_address_arg`	The argument follows the standard rules for dotted decimal notation. The following Internet Protocol 4 (IPv4) and Internet Protocol 6 (IPv6) address formats are supported: IPv4 (no port set, Lenovo Storage V series system uses default) 1.2.3.4 IPv4 with specific port 1.2.3.4:22 Full IPv6, default port 1234:1234:0001:0123:1234:1234:1234:1234 Full IPv6, default port, leading zeros suppressed 1234:1234:1:123:1234:1234:1234:1234 Full IPv6 with port [2002:914:fc12:848:209:6bff:fe8c:4ff6]:23 Zero-compressed IPv6, default port 2002::4ff6 Zero-compressed IPv6 with port [2002::4ff6]:23
`dns_name`	This is the dotted domain name for the system subnet.
`hostname`	The host name assigned to the system. This name can be different from the system name, and is modifiable. A combination of the host name and the `dns_name` is used to access the system, for example: https://hostname.
`capacity_value`	The capacity expressed within a range of 512 bytes to 2 petabytes (PB). Tip: Specify the capacity as megabytes (MB), kilobytes (KB), gigabytes (GB), or PB. When using MB, specify the value in multiples of 512 bytes. A capacity of 0 is valid for a striped or sequential volume. The smallest number of supported bytes is 512.
`node_id`	A node ID differs from other IDs in that it is a unique ID assigned when a node is used to create a system, or when a node is added to a system. A `node_id` value is never reused in a system. Node IDs are internally represented as 64-bit numbers, and like other IDs, cannot be modified by user commands.
`xxx_id`	All objects are referred to by unique integer IDs, assigned by the system when the objects are created. All IDs are represented internally as 32-bit integers; node IDs are an exception. IDs in the following ranges identify the various types of objects: node_id: A positive decimal integer greater than or equal to 1 mdisk_grp_id: 0–127 io_grp_id: 0–3 (See Note.) mdisk_id: 0–4095 vdisk_id: 0–8191 copy_id: 0–1 host_id: 0–1023 flash_const_grp_id: 0–255 remote_const_grp_id: 0–255 fcmap_id: 0–4095 rcrel_id: 0–8191 controller_id: 0–63 Note: The io_group 4 exists but is used only in certain error recovery procedures. These IDs, like node IDs, cannot be modified by user commands. Note: IDs are assigned at run time by the system and cannot be relied upon to be the same after; for example, the configuration restoration. Use object names in preference to IDs when working with objects.
`xxx_list`	A colon-delimited list of values of type `xxx`.
`wwpn_arg`	The Fibre Channel worldwide port name (WWPN), expressed as a 64-bit hexadecimal number and consisting of the characters 0–9, a–f, and A–F; for example: `1A2B30C67AFFE47B`. Note: Entering `WWPN 0` in the command string causes a command failure.
`panel_name`	This is a string of up to six characters corresponding to the number on the printed label below the display on the front panel of a node in the system.
`sequence_number`	A 32-bit unsigned integer, expressed in decimal format.
`csi_num_arg`	A 32-bit unsigned integer, expressed in decimal format.
`percentage_arg`	An 8-bit unsigned integer, expressed in decimal 0–100 format.
`extent_arg`	A 32-bit unsigned integer, expressed in decimal format.
`num_extents_arg`	A 32-bit unsigned integer, expressed in decimal format.
`threads_arg`	An 8-bit unsigned integer, expressed in decimal format. Valid values are 1, 2, 3, or 4.
`velocity_arg`	The fabric speed in gigabytes per second (GBps). Valid values are 1 or 2.
`timezone_arg`	The ID as detailed in the output of the lstimezones command.
`timeout_arg`	The command timeout period. An integer from 0 to 600 (seconds).
`stats_time_arg`	The frequency at which statistics are gathered. Valid values are 1 to 60 minutes in increments of 1 minute.
`directory_arg`	Specifies a directory, file name filter, or both, within the specified directory. Valid directory values are: /dumps /dumps/audit /dumps/cimom /dumps/configs /dumps/elogs /dumps/feature /dumps/iostats /dumps/iotrace /home/admin/upgrade The file name filter can be any valid file name, containing a maximum of 128 characters, with or without the wildcard (, an asterisk), and appended to the end of a directory value. Valid characters are: . (the field must not start with, end with, or contain two consecutive periods) / - _ a–z A–Z 0–9
`locale_arg`	The system locale setting. Valid values are: 0 en_US: US English (default) 1 zh_CN: Simplified Chinese 2 zh_TW: Traditional Chinese 3 ja_JP: Japanese 4 fr_FR: French 5 de_DE: German 6 it_IT: Italian 7 es_ES: Spanish
`key_arg`	A user-defined identifier for a secure shell (SSH) key, containing a maximum of 30 characters.
`user_arg`	Specifies the user: admin or service.
`copy_rate`	A numeric value of 0–100.
`copy_type`	Specifies the Mirror copy type: Metro or Global.

The maximum number of values entered into a colon-separated list is 128; exceeding this maximum number returns an error.
