Host commands

Edit online

Use the host commands to work with host objects on your system.

addhostclustermember
Use the addhostclustermember command to add a host object to a host cluster.
addhostiogrp
Use the addhostiogrp command to map I/O groups to an existing host object.
addhostport
chhost
Use the chhost command to change the name or type of a host object. This command does not affect any existing host mappings.
chhostcluster
Use the chhostcluster to change the name, type, or site of a host cluster object that is part of a host cluster.
lshost
Use the lshost command to generate a list with concise information about all the hosts visible to the system and detailed information about a single host.
lshostcluster
Use the lshostcluster command to generate a list with concise information about all the host clusters that are defined on the system or detailed information about a single host cluster.
lshostclustermember
Use the lshostclustermember command to generate a list with host information for hosts that belong to the specified host cluster.
lshostclustervolumemap
Use the lshostclustervolumemap command to display a list of volumes that are mapped to all host clusters (or to a specific host cluster).
lshostiogrp
Use the lshostiogrp command to display a list the I/O groups that are associated with a specified host.
lshostiplogin
Use the lshostiplogin command to list the login session type such as associated host object, login counts login protocol and other details for hosts that are identified by their iSCSI Qualified Name (IQN) and logged in to Ethernet ports that are configured with IP addresses.
lsiscsiauth
Use the lsiscsiauth command to list the Challenge Handshake Authentication Protocol (CHAP) secret that is configured for authenticating an entity to the system.
mkhost
Use the mkhost command to create a logical host object.
mkhostcluster
Use the mkhostcluster command to create a host cluster object.
mkvolumehostclustermap
Use the mkvolumehostclustermap command to generate a new mapping between a volume and a host cluster on a clustered system. This volume is then accessible for input or output (I/O) operations to the specified host cluster.
rmhost
Use the rmhost command to delete a host object.
rmhostcluster
Use the rmhostcluster command to remove a host cluster.
rmhostclustermember
Use the rmhostclustermember command to remove a host from a host cluster object.
rmvolumehostclustermap
Use the rmvolumehostclustermap command to remove an existing host cluster mapping to a volume on a clustered system.
rmhostiogrp
Use the rmhostiogrp command to delete mappings between one or more input/output (I/O) groups and a specified host object.
rmhostport
Use the rmhostport command to delete worldwide port names (WWPNs) Internet Small Computer System Interface (iSCSI) names, or NVMe Qualified Names (NQNs) from an existing host object.
