EXTENDED SELF-TEST COMPLETION MINUTES field
The EXTENDED SELF-TEST COMPLETION MINUTES field contains advisory data that is the time in minutes that the device server
requires to complete an extended self-test provided the device server is not interrupted by subsequent commands and no
errors occur during processing of the self-test. The application client should expect the self-test completion time to exceed the
value in this field if other commands are sent to the logical unit while a self-test is in progress or if errors occur during the
processing of the self-test. If a device server supports SELF-TEST CODE field values other than 000b for the SEND DIAGNOSTIC
command (see 3.46) and the self-test completion time is greater than 18 hours, then the device server shall support the
EXTENDED SELF-TEST COMPLETION MINUTES field. A value of 0000h indicates that the EXTENDED SELF-TEST COMPLETION
MINUTES field is not supported. A value of FFFFh indicates that the extended self-test takes 65 535 minutes or longer.
POA_SUP bit
1 A power on activation supported (POA_SUP) bit set to one indicates that the device server supports a WRITE BUFFER command with the
MODE field set to 0Dh (see 3.70.10) and the PO_ACT bit set to one.
0 A POA_SUP bit set to zero indicates that the device server does not support a WRITE BUFFER command with the MODE field set to 0Dh
and the PO_ACT bit set to one.
HRA_SUP bit
1 A hard reset activation supported (HRA_SUP) bit set to one indicates that the device server supports a WRITE BUFFER command with
the MODE field set to 0Dh (see 3.70.11) and the HR_ACT bit set to one.
0 A HRA_SUP bit set to zero indicates that the device server does not support a WRITE BUFFER command with the MODE field set to 0Dh
and the HR_ACT bit set to one.
VSA_SUP bit
1 A vendor specific activation supported (VSA_SUP) bit set to one indicates that the device server supports a WRITE BUFFER command
with the MODE field set to 0Dh (see 3.70.10) and the VSE_ACT bit set to one.
0 A VSA_SUP bit set to zero indicates that the device server does not support a WRITE BUFFER command with the MODE field set to 0Dh
and the VSE_ACT bit set to one.
MAXIMUM SUPPORTED SENSE DATA LENGTH field
The MAXIMUM SUPPORTED SENSE DATA LENGTH field indicates the maximum length in bytes of sense data (see 2.4) that the
device server is capable of returning in the same I_T_L_Q nexus transaction as the status. A MAXIMUM SUPPORTED SENSE DATA
LENGTH field set to zero indicates that the device server does not report a maximum length. This value shall be less than or equal
to 252.
