How can I determine why `parted -l` might report "unrecognised disk label" on Red Hat Enterprise Linux 6?

Solution Unverified - Updated -

Issue

When I run "parted -l" command, some of the devices report unrecognised disk label similar to below:

# parted -l | grep unrecognised
Error: /dev/sdc: unrecognised disk label
Error: /dev/sdd: unrecognised disk label
Error: /dev/sdf: unrecognised disk label
Error: /dev/mapper/mpathc: unrecognised disk label
Error: /dev/mapper/mpathbp3: unrecognised disk label
Error: /dev/sdh: unrecognised disk label

Environment

  • Red Hat Enterprise Linux 6 (RHEL6)
  • Several multipath'd devices presented from a SAN (in this case, an IBM 1746 FAStT)
  • parted -l reports that some of the devices have an unrecognised disk label.

  • Some devices on the system:

    • Multipath devices that legitimately do not have a partition on them
    • Device-mapper device (eg. multipath device or multipath partition) with LVM PV on it.
    • Active/Passive or Active/Ghost (RDAC) SAN.
