Physical Volume Implementation Limitations

When composing a physical volume from a DASD, the following implementation restrictions apply to DASD characteristics:

  • 1 to 32 physical volumes per volume group
  • 1 to 128 physical volumes in a big volume group
  • The partition size is restricted to 2**n bytes, for 20 <= n <= 30
  • The physical block size is restricted to 512 or 4096 bytes
