vcb proxy - forgot to disable automount and now the vmfs is fucked up

ever wondered what you should do if you forgot to disable automount on the vmware vcb proxy and your windows server takes the volume? now i am *hardly* telling you you HAVE TO call vmware they know how to fix it but for experimental purposes in *test labs only* here comes a nice how-to for bringing your vmfs back working:

Check with “fdisk -lu” what the current ID value is of the volumes, it´s SFS if Windows wrecked it. Write all the devices down and label them again as VMFS:
fdisk /dev/sd? (? the letter for that specific volume)

p
d
n
p
1
default
t
fb
X
b
1
128 (disk alignment, check your SAN manual for the correct value, 128 is correct in most cases…) W

Now rescan the HBA devices, esxcfg-rescan vmhba0 etc etc.
