380 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
Deleting ports from a defined host
If a mistake is made while adding a port, or if an HBA is removed from a server that is defined 
within the Storwize V7000, use the rmhostport command to remove WWPN definitions from 
a host.
Before removing the WWPN, ensure that it is the correct WWPN by issuing the lshost 
command, as shown in Example 8-35.

When the WWPN or iSCSI IQN that needs to be deleted is known, use the rmhostport 
command to delete a host port, as shown in Example 8-36.
Example 8-36   Using the rmhostport command to remove a WWPN
IBM_Storwize:ITSO-V7000:superuser>rmhostport -fcwwpn 2100000E1E30E597 ITSO-VMHOST-01
IBM_Storwize:ITSO-V7000:superuser>
Use the command to remove the iSCSI IQN, as shown in Example 8-37.
Example 8-37   Removing iSCSI port from the host
IBM_Storwize:ITSO-V7000:superuser>rmhostport -iscsiname iqn.1994-05.com.redhat:e6ddffaab567 
RHEL-Host-05
IBM_Storwize:ITSO-V7000:superuser>
Use the command to remove the NVMe NQN, as shown in Example 8-38.
Example 8-38   Removing NQN port from the host
IBM_Storwize:ITSO-V7000:superuser>rmhostport -nqn nqn.2016-06.io.rhel:875adad3345 
RHEL-Host-08
IBM_Storwize:ITSO-V7000:superuser>
Note: Multiple ports can be removed at one time by using the separator or colon (:) 
between the port names, as shown in the following example: 
rmhostport -hbawwpn 210000E08B054CAA:210000E08B892BCD Angola
