CentOS - Apr 2010 - removing inaffective SAN partitions from the system .....

Dear All,

     I have installed CentOS release 5.2 (Final). EMC SAN partition is mounted
by using EMC Powerpath for resolving multiple paths. I was able write and read
data over to SAN partition without any issues.

     Subsequently I have unmounted EMC SAN partition from the system and deleted
LUN using Navisphere user interface. After rebooting system, I still see SAN
mappings in system.

Here is the affected partition mappings ....

=============================cat /proc/partitions
=============================major minor  #blocks  name
   8    16    1048576 sdb
   8    48    1048576 sdd
   8    80    1048576 sdf
   8   112    1048576 sdh
===========================

When I try to print information using parted, I am getting the following
information ....
========================================================================================#parted
/dev/sdb
GNU Parted 1.8.1
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) print                                                           
Error: Unable to open /dev/sdb - unrecognised disk label.                
(parted)                     
============================================
I would like to get rid of partition mappings from the system. Anyone has any
solution for this problem please.

with regards,
