The key to this is using a few MDT database variables:
- OSDPartitions0BOOTABLE=
- OSDPartitions0FILESYSTEM=
- OSDPartitions0QUICKFORMAT=
- OSDPartitions0SIZE=
- OSDPartitions0SIZEUNITS=
- OSDPartitions0TYPE=
- OSDPartitions0VOLUMELETTERVARIABLE=
- OSDPartitions0VOLUMENAME=
This variables will overrule de standard drive configuration defined in the Task Sequence. MDT can configure a maximum of 2 partitions (per disk) using the database variables OSDPartitions0 and OSDPartitions1Field OSDPartitions0SIZE will define the partition size in units specified in OSDPartitions0SIZEUNITS, these can be MB, GB or %. When using % this will define the percentage of remaining diskspace so if partition 0 was defined as 40Gb the specification of 100 % will result in the allocation of 100% of the rest of the remaining disk space to that second partition.
this script will use DHCP exports as created by another script you can find on my blog , if no, by DHCP exported MAC address, can be found the script will ask for a MAC address. it will check the MAC address for validity and the script will ask you to create a new MDTcomputer object if the machine cannot be found.
