Removing Fibre Channel Path WWNs
• To remove a WWN from an existing host, issue the removehost <host_name> <WWN>
command, where:
◦ <host_name> is the name of the host being modified.
◦ <WWN> is the FC path being removed.
Removing iSCSI Path iSCSI Names
• To remove an iSCSI Name from an existing host, issue the removehost -iscsi
<host_name> <iSCSI_name> command, where:
◦ <host_name> is the name of the host being modified.

Configuring iSCSI CHAP Authentication Information
A host with an iSCSI path can be modified as an initiator or target with iSCSI CHAP authentication
information. You cannot set the target CHAP authentication information before setting the initiator
CHAP authentication information.
• To configure a host as a CHAP initiator, issue the sethost initchap <secret>
<host_name> command.
• To configure a host as a CHAP target, issue the sethost targetchap <secret>
<host_name> command.
For both commands listed above, <secret> is the user-defined security key and <host_name>
is the name of the host you are modifying.
During configuration, you can also optionally set the CHAP name and set the CHAP secret as a
hex number. See the HP 3PAR InForm OS Command Line Interface Reference for further information.
Removing iSCSI CHAP Authentication Information
To remove CHAP authentication information from a host with an iSCSI path, issue one of the
following commands:
• sethost removechap -target <host_name>
• sethost removechap <host_name>
For both commands listed above:
◦ <host_name> is the name of the host you are modifying.
◦ The -target argument is specified for removal of target CHAP authentication only.
