5.3.6 Application Tag mode page (0Ah/02h)
The Application Tag mode page (see table 367) specifies the Application Tag that a device server configured for protection
information (see 5.3.6) shall use for each LBA range if the ATO bit in the Control mode page (see 5.3.12) is set to one. The mode
page policy (see 5.4.14) for this page shall be shared.
If a method not defined by this standard changes the parameter data to be returned by the device server in the Application Tag
mode page, then the device server shall establish a unit attention condition for the initiator port associated with every I_T nexus
with the additional sense code set to MODE PARAMETERS CHANGED.
The parameters saveable (PS) bit, the subpage format (SPF) bit, the PAGE CODE field, the SUBPAGE CODE field, and the PAGE
LENGTH field are defined in SPC-5.
The SPF bit, the PAGE CODE field, the SUBPAGE CODE field, and the PAGE LENGTH field shall be set to the values shown in Table
367.
