4.4 Maintenance, Diagnostic Commands

C141-C008 4-185

Be sure to set up PCV in 1 when you transfer information on ESI. PCV works

supposing that it is ignored and 00 is set up in the page code even if any page

code is specified when 0 is set up.

Information from Enclosure is transferred to INIT by specifying the above page

code with CDB with the designation of PCV=1 by the following page format.

Remark:

The page code 0x09-0x0F is a reserve in the specification of SES/ESI. It is

issued as an ESI command to Enclosure at present without taking an error

when the 0x09-0x0F is specified in the page code.

When it has the 0x80-0x8F specified, it is issued as Vendor unique Page as

an ESI command to Enclosure.
