ESXi 5.0 file system GUIDs

Details

File system GUIDs are necessary when using partedUtil on ESXi 5.0 hosts.

Solution

ESXi 5.0 has the following file system GUIDs:
Partition type
GUID
VMFS Datastore
2AE031AA-0F40-DB11-9590000C2911D1B8
VMKCore Diagnostic
8053279D-AD40-DB11-BF97000C2911D1B8
VMware Reserved
CDEF9891-C031-DB11-8F78000C2911D1B8
 
 
The GUIDs in this table are written assuming a little-endian byte order. The GUID for VMFS is written as 0xaa31e02a, 0x400f, 0x11db, 0x95, 0x90, 0x00, 0x0c, 0x29, 0x11, 0xd1, 0xb8, which corresponds to the 16 byte sequence 2a e0 31 aa 0f 40 db 11 95 90 00 0c 29 11 d1 b8 - only the first three blocks are byte swapped.
