partedUtil

NOTE: For ESXi/ESX 4.1 and later, use getptbl/setptbl

This also works:

cd /dev/disks
partedUtil get eui.b42c42d3f4bb4ab0002471704404840c

Quick Partition:

cd /dev/disks
ls
DEVICE=eui.b42c42d3f4bb4ab0002471704404840c

echo "Device: $DEVICE"
DEVICE_SECTORS=`partedUtil get $DEVICE | head | awk '{print $4}'`
echo "Device Sectors: $DEVICE_SECTORS"
echo "Clearing Partitions..."
PARTITIONS=`partedUtil get $DEVICE | grep -v $DEVICE_SECTORS`
echo "$PARTITIONS" | while IFS= read line ; do
  PARTITION=`echo $line | awk '{print $1}' | grep .`
  if [ $? -ne 0 ] ; then continue ; fi
  echo "Deleting partition: $PARTITION"
  partedUtil delete $DEVICE $PARTITION
done
NEW_SECTORS=`expr $DEVICE_SECTORS / 1024 \* 1024 - 1`
partedUtil setptbl $DEVICE gpt "1 2048 $NEW_SECTORS AA31E02A400F11DB9590000C2911D1B8 0"
# 251 does not appear to work:??
partedUtil setptbl "/vmfs/devices/disks/naa.6b4e0c0dfafafafafafafafafafafafa" gpt "1 2048 800780287 251 0"

Note: for the "800780287", take "floor( 800781251 / 1024 ) * 1024 - 1"


One partition:

# partedUtil get /vmfs/devices/disks/naa.6b4e0c0dfafafafafafafafafafafafa
49846 255 63 800781251
1 2048 800780287 0 0

# partedUtil getptbl /vmfs/devices/disks/naa.6b4e0c0dfafafafafafafafafafafafa
gpt
49846 255 63 800781251
1 2048 800780287 AA31E02A400F11DB9590000C2911D1B8 vmfs 0

Delete partition:

partedUtil delete /vmfs/devices/disks/naa.6b4e0c0dfafafafafafafafafafafafa 1

Create partition: (Note: VMFS = 0xFB (hex) = 251 (decimal) = AA31E02A400F11DB9590000C2911D1B8 (GUID))

partedUtil setptbl "/vmfs/devices/disks/naa.6b4e0c0dfafafafafafafafafafafafa" gpt "1 2048 800780287 AA31E02A400F11DB9590000C2911D1B8 0"
# 251 does not appear to work:??
partedUtil setptbl "/vmfs/devices/disks/naa.6b4e0c0dfafafafafafafafafafafafa" gpt "1 2048 800780287 251 0"

Note: for the "800780287", take "floor( 800781251 / 1024 ) * 1024 - 1"
