I just encountered the following problem whenever the contractor
changing shared storage interface from iSCSi to Fibre.

[root@host02 ~]# pvscan
  connect() failed on local socket: Connection refused
  Internal cluster locking initialisation failed.
  WARNING: Falling back to local file-based locking.

to fix above.. and enable for usage..

edit the /etc/lvm/lvm.conf

search for filter.

    # A filter that tells LVM2 to only use a restricted set of devices.
    # The filter consists of an array of regular expressions.  These
    # expressions can be delimited by a character of your choice, and
    # prefixed with either an 'a' (for accept) or 'r' (for reject).
    # The first expression found to match a device name determines if
    # the device will be accepted or rejected (ignored).  Devices that
    # don't match any patterns are accepted.
 
    # Be careful if there there are symbolic links or multiple filesystem
    # entries for the same device as each name is checked separately against
    # the list of patterns.  The effect is that if any name matches any 'a'
    # pattern, the device is accepted; otherwise if any name matches any 'r'
    # pattern it is rejected; otherwise it is accepted.
 
    # Don't have more than one filter line active at once: only one gets used.
 
    # Run vgscan after you change this parameter to ensure that
    # the cache file gets regenerated (see below).
    # If it doesn't do what you expect, check the output of 'vgscan -vvvv'.
 
 
    # By default we accept every block device:
    filter = [ "a/.*/" ]

change the line

filter= ["a/.*/"]

to something like.

    filter = [ "a/sda[1-9]$/" "a/emcpower.*/" "r/.*/" ]


then run the following to re-scan..

vgscan -vvvv

done.. !
