lsvdiskhostmap

Use the lsvdiskhostmap command to list the volumes to the host mapping. These hosts have the specified volumes mapped to them; the volume is visible to these hosts.

Syntax

 lsvdiskhostmap    [  -nohdr  ]   [  -delim  delimiter  ]   {  vdisk_id  |  vdisk_name  }

Parameters

-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.
Note: If there is no data to be displayed, headings are not displayed.
-delim delimiter
(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.
vdisk_id | vdisk_name
(Required) Specifies the ID or name of the volume. The clustered system displays a list of all the hosts to which this volume is mapped and the Small Computer System Interface (SCSI) ID by which the volume is mapped.

Description

This command displays a list of host IDs and names. These hosts have the specified volume mapped to them; that is, the volume is visible to these hosts. The SCSI LUN ID is also displayed. The SCSI LUN ID is the ID by which the volume is recognized by the host.

Determining the host that a volume is mapped to: List the hosts that this volume is mapped to, by issuing the following command:

lsvdiskhostmap vdisk_id | vdisk_name

where vdisk_id | vdisk_name is the name or ID of the volume. A list is displayed. Look for the host name or ID to determine which host this volume is mapped to. If no data is displayed, the volume is not mapped to any hosts.
The command returns the following values:
id
Specifies the ID of the volume in the output for lsvdiskhostmap.
name
Specifies the name of the volume in the output for lsvdiskhostmap.
SCSI_id
Specifies the SCSI ID.
host_id
Specifies the ID of the host.
host_name
Specifies the name of the host.
vdisk_UID
Specifies the UID of the volume.
IO_group_id
Specifies the ID of the input/output (I/O) group in which the host volume mapping exists.
IO_group_name
Specifies the name of I/O group in which the host volume mapping exists.
host_cluster_id
Indicates the unique ID for a host system.
host_cluster_name
Indicates the unique name for a host system.
