If the ESI request contains a valid Action Code and non-zero Parameter Length,
the drive responds with a write operation with the requested information. Table
1.33 defines the format of the EIE page. Tables 1.34, 1.35, 1.36, 1.38, and 1.39
define the page contents for the identified action codes.
The Initiate Loop Initialization Action Code (03h) does not include a transfer of
information to the enclosure. The Action Specific bits in the Enclosure Request
define the operation to be performed. See Table 1.37.
The Action Specific bits for the remaining Action Codes are 0.
