Use the mkhost command to create a logical
host object.
Syntax
mkhost [ -name new_name ] { -saswwpn wwpn_list | -fcwwpn wwpn_list | -iscsinameiscsi_name_list } [ -iogrp iogrp_list ] [ -mask port_login_mask ] [ -force ] [ -type { hpux | tpgs | generic | openvms | adminlun | hide_secondary } ] { [ -site { site_name | site_id } -hostcluster { host_cluster_id | host_cluster_name } ] }
Parameters
- -namenew_name
- (Optional) Specifies a name or label for the new host object.
- -saswwpnwwpn_list
- (Required if you do not use -iscsiname or -fcwwpn)
Specifies a list of Serial Attached SCSI (SAS) WWPNs with a 16-character hexadecimal string.
- -fcwwpnwwpn_list
- (Required if you do not use -saswwpn or -iscsiname)
Specifies a list of Fibre Channel (FC) WWPNs with a 16-character hexadecimal string.
- -iscsinameiscsi_name_list
- (Required if you do not use -fcwwpn or -saswwpn)
Specifies the comma-separated list of iSCSI names to add to the host.
At least one WWPN or iSCSI name must be specified. You cannot use
this parameter with the -fcwwpn or -saswwpn parameter.
- -iogrp iogrp_list
- (Optional) Specifies a set of one or more input/output (I/O) groups
that the host can access the volumes from. I/O groups are
specified using their names or IDs, separated by a colon. Names and
IDs can be mixed in the list. If this parameter is not specified,
the host is associated with all I/O groups.
- -mask port_login_mask
- (Optional) Specifies which node target ports a host can access and the Fibre Channel (FC) port
mask for the host. Worldwide port names (WWPNs) in the host object must access volumes from the node
ports that are included in the mask and are in the host object's I/O group. The port mask is 64
binary bits and is made up of a combination of 0's and 1's, where 0 indicates that the corresponding
FC I/O port cannot be used and 1 indicates that it can be used. The right-most bit in the mask
corresponds to FC I/O port 1. Valid mask values might range from 0000 (no ports
enabled) to 1111111111111111111111111111111111111111111111111111111111111111 (all
ports enabled). For example, a mask of 111111101101 enables ports 1, 3, 4, 6, 7, 8,
9, 10, 11, and 12.
- -force
- (Optional) Specifies that a logical host object be created without
validation of the WWPNs.
- -typehpux |tpgs|generic|openvms|adminlun|hide_secondary
- (Optional) Specifies the type of host. The default is generic.
The tpgs parameter enables extra target-port
unit attentions. Refer to Lenovo Storage V series host
attachment documentation for more information on the hosts that require
the type parameter.
- -hostclusterhost_cluster_id | host_cluster_name
- (Optional) Specifies the host cluster ID (numerical value) or name (alphanumeric value) that the
new host object is created in.
Description
The mkhost command associates one or more HBA WWPNs or
iSCSI names with a logical host object. This command creates a new host. The ID is displayed when
the command completes. You can subsequently use this object when you map volumes to hosts by using
the mkvdiskhostmap command. If you create a
host directly inside a host cluster by specifying -hostcluster, it inherits any
shared mappings that exist.
Issue
the mkhost command only once. The clustered system
scans the fabric for WWPNs in the host zone. The system itself cannot
filter into the hosts to determine which WWPNs are in which hosts.
Therefore, you must use the mkhost command to identify
the hosts.
After you identify the hosts, mappings are created
between hosts and volumes. These mappings effectively present the
volumes to the hosts to which they are mapped. All WWPNs in the host
object are mapped to the volumes.
Some HBA device drivers do not log in to the
fabric until they can see target logical unit numbers (LUNs). Because
they do not log in, their WWPNs are not recognized as candidate ports.
You can specify the force parameter with this
command to stop the validation of the WWPN list.
This
command fails if you add the host to an I/O group that is associated
with more host ports or host objects than is allowed by the limits
within the system.
For additional information, see the
mkvdiskhostmap, lssasportcandidate, and
lsfcportcandidate commands.
An invocation example
mkhost -name hostone -saswwpn 210100E08B251DD4:210100F08C262DD8 -force -mask 111111101101
The resulting output:
Host id [1] successfully created
An invocation example
mkhost -iscsiname iqn.localhost.hostid.7f000001 -name newhost
The
resulting output:
Host, id [10], successfully created
An invocation example
mkhost -fcwwpn 210100E08B251EE6:210100F08C262EE7 -type openvms
The resulting output:
Host, id [1], successfully created
An invocation example
mkhost -fcwwpn 210100E08B251EE6 -site site1
The resulting output:
Host, id [1], successfully created
