Solution Verified - Updated -

Issue

  • Disk geometry mismatch errors on SAN disks when partprobe is run:
    [root@redhat ~]# partprobe
    Warning: The disk CHS geometry (239,255,63) reported by the operating system does not match the geometry stored on the disk label (937,128,32). 
    Warning: The disk CHS geometry (239,255,63) reported by the operating system does not match the geometry stored on the disk label (937,128,32). 
    Warning: The disk CHS geometry (239,255,63) reported by the operating system does not match the geometry stored on the disk label (937,128,32). 
    
  • disklabel checksum error in fdisk output:
    [root@redhat ~]# fdisk -l /dev/sdjs
    Detected sun disklabel with wrong checksum.
    Probably you'll have to set all the values,
    e.g. heads, sectors, cylinders and partitions
    or force a fresh label (s command in main menu)
    
  • disk corruption is suspected
