lsiogrp

Use the lsiogrp command to display a concise list or a detailed view of input/ouput (I/O) groups visible to the clustered system (system).

The list report style can be used to obtain the following two styles of report:

A list containing concise information about all the I/O groups that are visible to the system. Each entry in the list corresponds to a single I/O group.
The detailed information about a single I/O group.

Syntax

lsiogrp [ -filtervalueattribute=value ] [ -nohdr ] [ -delimdelimiter ] [ -filtervalue? ] [ -bytes ] [ { object_id | object_name } ]

Parameters

-filtervalueattribute=value

(Optional) Specifies a list of one or more filters. Only objects with a value that matches the filter attribute value are returned. If a capacity is specified, the units must also be included.

Note: Some filters allow the use of a wildcard when you enter the command. The following rules apply to the use of wildcard characters when using the CLI:

The wildcard character is an asterisk (*), which must be the first or last character in the string.
The command can contain a maximum of one wildcard.
When you use a wildcard, enclose the filter entry within double quotation marks (""), as follows:
```
lsiogrp -filtervalue "name=md*"
```

-nohdr

(Optional) By default, headings are displayed for each column of data in a concise style view, and for each item of data in a detailed style view. The -nohdr parameter suppresses the display of these headings.

-delimdelimiter

(Optional) By default in a concise view, all columns of data are space-separated. The width of each column is set to the maximum possible width of each item of data. In a detailed view, each item of data has its own row, and if the headers are displayed the data is separated from the header by a space. The -delim parameter overrides this behavior. Valid input for the -delim parameter is a one byte character. If you enter -delim : on the command line, the colon character (:) separates all items of data in a concise view; for example, the spacing of columns does not occur. In a detailed view, the data is separated from its header by the specified delimiter.

-filtervalue?

(Optional) Displays the valid filter attributes for the lsiogrp command:

HWS_name
HWS_unique_id
node_count
name
id
host_count

-bytes

(Optional) Displays all capacities as bytes.

object_id | object_name

(Optional) Specifies the name or ID of an object. When you use this parameter, the detailed view of the specific object is returned and any value that is specified by the -filtervalue parameter is ignored. If you do not specify the object_id | object_name parameter, the concise view of all objects matching the filtering requirements that is specified by the -filtervalue parameter are displayed.
