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.
