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

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"

partedUtil mklabel /vmfs/devices/disks/naa.6b4e0c0dfafafafafafafafafafafafa msdos
