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:

Syntax

 lsiogrp      [  -filtervalue  attribute=value  ]   [  -nohdr  ]   [  -delim  delimiter  ]     [  -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 you use 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 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 1-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 that match the filtering requirements that are specified by the -filtervalue parameter are displayed.

  • yes
  • no
encryption_supported
Indicates whether the I/O group supports encryption for attached drives. The possible values are:
  • yes
  • no
flash_copy_maximum_memory
Identifies the maximum memory that can be set for the specified I/O group. The value must be a numeric string in the range 552 MB - 2048 MB.
site_id
Identifies the site ID for the I/O group. The possible values are :
  • 1
  • 2
site_name
Identifies the site name for the I/O group. The value must be an alphanumeric string or blank.
compression_total_memory
Indicates the amount of RAM allocated for compression in the specified I/O group.
fctargetportmode
