Have you tried. Removing the wwid from /etc/multipath.conf
And reload multipathd
Not sure if /etc/multipath/wwid is updated automatically. But when we had to bring a new LUN into multipath. The steps were to add WWID to multipath.conf and reload multipathd. This was in RHEL 5.5 though. Now if we consider going backwards the earlier steps would work. Not tried and tested

Hi all,
I'm wondering if anyone knows whether Solaris IPMP can be configured such that the IPs of the physical NICs are not available to applications when using IP4 or if the group address and the underlying physical address are always present?
Thanks. (3 Replies)

mp_deregisterplugin
MP_DeregisterPlugin(3MPAPI) Common Multipath Management Library Functions MP_DeregisterPlugin(3MPAPI)
NAME
MP_DeregisterPlugin - deregister a plugin
SYNOPSIS
cc [ flag... ] file... -lMPAPI [ library... ]
#include <mpapi.h>
MP_STATUS MP_DeregisterPlugin(MP_WCHAR *pPluginId);
PARAMETERS
pPluginId A pointer to a Plugin ID previously registered using the MP_RegisterPlugin(3MPAPI) API.
DESCRIPTION
The MP_DeregisterPlugin() function deregisters a plugin from the common library.
The plugin will no longer be invoked by the common library. This API does not dynamically remove the plugin from a running library
instance. Instead, it prevents an application that is currently not using a plugin from accessing the plugin. This is generally the behav-
ior expected from dynamically loaded modules.
RETURN VALUES
MP_STATUS_INVALID_PARAMETER
The pPluginId parameter is null or specifies a memory area that is not executable.
MP_STATUS_UNKNOWN_FN
The pPluginId parameter is not the same as a previously registered function.
MP_STATUS_SUCCESS
The pPluginId parameter is deregistered successfully.
MP_STATUS_FAILED
The pPluginIdparameter deregistration is not possible at this time
FILES
/etc/mpapi.conf MPAPI library configuration file
