Use the command rmvpath to remove all paths

root@linux:~ # rmvpath
Continuing will remove all IBM vpath devices.
Do you want to continue (y/n)?: n

This is a little man page for the rmvpath command

root@linux:~ # rmvpath ?

NAME
rmvpath — remove IBM vpath devices.

SYNOPSIS
rmvpath [OPTION]… [VPATH]

DESCRIPTION
rmvpath can be invoked with no options or with the name
of a specific vpath device to remove, and/or a specific
configuration file.

OPTIONS
-f [FILENAME] indicate a specific configuration file to update
rmvpath will default to /etc/vpath.conf
[VPATH] if no vpath is specified, all IBM vpath
devices will be removed
debug prints debug information to stdout

DEFAULTS
o default configuration file is /etc/vpath.conf
o all vpaths are removed

To remove /dev/vpath4, updating /tmp/configuration:

rmvpath -f /tmp/configuration vpath4

I removed only the vpathi disk here

root@linux:~ # rmvpath vpathi
Remove vpathi requested
Deleting file: /dev/vpathi
