Removing Host Paths - HP 3PAR StoreServ 7200 2-node Administrator's Manual

1. Use the HP 3PAR CLI command servicehost copy to create an inactive host on the system
port to which you wish to move the host. The inactive host created with this command is
identical to the active host that is to be relocated to this port.
The servicehost copy command automatically exports all volumes that are currently
exported to the active host to the new, inactive host once it is created. For more information
about active and inactive hosts, see
The VLUNs from the specified source port (src_node:slot:port) are copied from the host
WWNs or iSCSI Names matching the specified pattern (WWN_or_iSCSI_name_pattern)
to the specified destination port (dest_node:slot:port). If necessary, the port is reset to
target mode.
To create an inactive host on the system port to which you wish to move the host, issue the
servicehost copy <src_node:slot:port> <WWN_or_iSCSI_name_pattern>
<dest_node:slot:port> command, where:
<src_node:slot:port> is the current port location.
<WWN_or_iSCSI_name_pattern> specifies that the indicated WWN or iSCSI Name
is treated as a glob-style pattern.
<dest_node:slot:port> is the destination port location.
2. Remove the host definitions from the old port or ports.
Removing the host definitions does not remove the old host paths. To remove the host paths,
see "Removing Host Paths" (page
with the old host port, issue the servicehost remove
[<node:slot:port>[<WWN_or_iSCSI_name> ... ]] command, where:
<node:slot:port> is the old port location.
<WWN> is the WWN path or paths to the host to be removed.
<iscsi_name> is the iSCSI path or paths to the host to be removed.
3. Disconnect the host from the system and then connect it to the new port.
The system discovers the host on the new port automatically by matching the WWNs or iSCSI
Names of the inactive host you created in
The HP 3PAR OS automatically changes the state of the host from inactive to active. The host
has immediate access to all volumes exported to the host.

Removing Host Paths

Host paths can be removed from the system before or after VLUNs are exported to the hosts. The
removehost command removes a system host path to an FC or iSCSI host. If one or more paths
are specified, the command removes only the specified paths; otherwise the entire host definition
is removed. If VLUNs have been exported to the host, issue the removehost -rvl <host_name>
command. For information about exporting VLUNs, see
The removehost CLI command is described in detail in the HP 3PAR Command Line Interface
Reference and the HP 3PAR CLI Help.
To completely remove a host definition from your system, issue the removehost <host_name>
[<WWN>... | <iscsi_name> ...] command, where:
<host_name> is the host definition to be removed.
<WWN>... is the WWN path or paths to the host to be removed.
<iscsi_name>... is the iSCSI path or paths to the host to be removed.
NOTE: Physically disconnecting a host server from the system port does not delete the host from
the system.
