Add VMware ESXi datastore to install disk using partedUtil
# For me atleast VMware ESXi fails to create a datastore on the drive i installed it on - although enough space is left over.
# You can still do it using partedUtil on the console.
# I'm using a 250 GB Sammsung 860 Evo in this example (/dev/disks/t10.ATA_____Samsung_SSD_860_EVO_250GB_______________S3YJNF0JC02559E____)
#
# First lets check the current partition layout using partedUtil getptbl
[root@oxygen-vmhost2:~] partedUtil getptbl /dev/disks/t10.ATA_____Samsung_SSD_860_EVO_250GB_______________S3YJNF0JC02559E____
