CLI, Modify Volume–Host Mapping
The steps involved in modifying host mappings are presented in “Mapping Volumes and Hosts” on page 64.
Deleting a mapping removes visibility from the host to the volume. The volume–host mapping scheme can be
modified at any time through the CLI by first deleting the current mapping using the
unpresent
command with
the options shown in Table 22. Then create a new mapping using the
present
command with the options
shown in Table 23.
Table 22:
Unpresent Command—CLI
Table 23:
Present Command
For example, assume Volume03 is mapped to hosts Prod01 and Prod02 and it needs to be mapped to hosts
Prod01 and Prod07 instead. The following sequence of commands changes the mapping as needed.
unpresent --volume=Volume03 Prod02
The mapping of Volume03 to host Prod02 is deleted and the mapping of Volume03 to host Prod01 remains
unaffected. The following message appears on the console when the unmapping completes:
Unpresenting 'Volume03' from 'Prod02':OK
The following
present
command creates the new mapping:
present --volume=Volume03 Prod07
Volume03 is mapped to host Prod07 and the following message appears on the console upon completion:
Presenting 'Volume03' to 'Prod07': OK
A subsequent
show volume
confirms that Volume03 is now mapped to hosts Prod01 and Prod07.

Volume or list of volumes (separated by blanks) to be
unmapped from this host.
--all
Following host name unmaps all volumes from a host.
Examples:
unpresent --volume=Volume7 Host00 Host01
unpresent --host=Host00 Volume07 Volume02
