PDO_CAPS enumeration (ehstorioctl.h)

  • Article

This enumeration describes the capabilities of Physical Device Objects (PDOs).

Syntax

typedef enum _PDO_CAPS {
  PDO_CAPABILITY_UNDEFINED,
  PDO_CAPABILITY_INC512_SET,
  PDO_CAPABILITY_INC512_CLEAR
} PDO_CAPS;

Constants

 
PDO_CAPABILITY_UNDEFINED
Command data block size granularity is undefined.
PDO_CAPABILITY_INC512_SET
Command data block size granularity of 512 bytes is supported.
PDO_CAPABILITY_INC512_CLEAR
Command data block size granularity of 1 byte is supported.

Remarks

A silo must support either PDO_CAPABILITY_INC512_SET or PDO_CAPABILITY_INC512_CLEAR. It may also indicate that both values are supported by returning a logical OR of these two bits.
