Create datastore in 5.5 error Call “HostStorageSystem.ComputeDiskPartitionInfo” for object “storageSystem” on ESXi “HOSTNAME” failed.

I kept getting the error ‘Call “HostStorageSystem.ComputeDiskPartitionInfo” for object “storageSystem” on ESXi “HOSTNAME” failed’ when I attempted to create a datastore from an old hard drive I had laying around.

Turns out ESXi was failing to format the existing partitions and I had to manually delete the partitions first,

Using SSH,

# esxcfg-scsidevs -l

this lists the disk devices, the device file will be /dev/disks/<NAME>

# partedUtil get /dev/disks/t10.ATA_…

this shows the partitions on the device

# partedUtil delete /dev/disks/t10.ATA_… 1

deletes partition 1
