PowerPath: Unable to boot the system after setting a global_filter in /etc/lvm/lvm.conf

Applying the global filter setting in the lvm.conf file, causing the host not to recognize the internal devices under RAID Configuration anymore.

Unable to boot the system after setting a 'global_filter' in '/etc/lvm/lvm.conf' but able to boot the system if the 'global_filter' is commented out.

The Error occurring during boot:

Timed out waiting for device dev-mapper-rhel00\x2dhome.device. Dependency failed for /home. Dependency failed for Local File Systems. Dependency failed for Relabel all file system, if necessary. Dependency failed for Mark the need to relabel after reboot. Dependency failed for Migrate local SELinux policy changes from the old store structure to the new structure.

"/" and "/home" was not able to get mounted while the filter settings were ON in the lvm.conf file.

The internal devices are under RAID control; since it is a local boot setup, the "/" and "/home" are created on the local disk and the SCSI disk representation for them is '/dev/md*'. There is no entry to accept '/dev/md*' in the global filter and hence causing the host to not accept the internal devices when the filter is applied in lvm.conf.

The physical Volume looks like this:

    Physical volume
  PV Name              /dev/md126p3
  VG Name               rhel00

Modify the filter to accept all md* devices as below to be able to discover the device and to mount "/" and "/home" as well when the server is booting:

global_filter = [ "a|/dev/./by-id/scsi-35001173101465378.|", "a|/dev/./by-id/scsi-0123456789abcdfc0.|", "a/md./",* "a/emcpower./", "r/sd./", "r/disk.*/" ]

Identify the underlying Physical Volume names needed at boot time and add them to the lvm.conf file accordingly.
