• SD - Sequential Delivery
The drive sets this field to 1b to request that the fabric deliver all frames in the same order they were transmitted. The
fabric sets this flag to 1b if it can honor this request. Since the drive does not support out of order frame delivery, the
drive checks the FLOGI_ACC to ensure that this field is set to 1b and will revert to PLDA behavior if it is not.
• DS - Dedicated Simplex
This flag only applies to class 1 service. The drive sets this field to 0b.
• Camp On - Camp-On
This flag only applies to class 1 service. The drive sets this field to 0b.
• BufC1 - Buffered Class 1
This flag only applies to class 1 service. The drive sets this field to 0b.
• Priority - Priority
This flag does not apply to class 3 service. The drive sets this field to 0b.
The Initiator Control Flags are not meaningful for FLOGI and are therefore reserved. The drive sets this field to 00h.
The Recipient Control Flags are not meaningful for FLOGI and are therefore reserved. The drive sets this field to 00h.
The Receive Data Field Size field is not meaningful for FLOGI and is therefore reserved. The drive sets this field to 00h.
The Concurrent Sequences field is not meaningful for FLOGI and is therefore reserved. The drive sets this field to 00h.
The End-to-End Credit field is not meaningful for FLOGI and is therefore reserved. The drive sets this field to 00h.
The Open Sequences per Exchange field is not meaningful for FLOGI and is therefore reserved. The drive sets this field to
00h.
The Class 6 Multi-cast RXID field is not meaningful for FLOGI and is therefore reserved. The drive sets this field to 00h.
17.3.6 Fabric Address Notification (FAN)
The FAN ELS is sent by an FL_Port to all previously logged in (FLOGI) NL_Ports after an initialization event has occurred.
An initialization event can be a LIP or any other event that may cause a Port to change its ID. The FAN ELS is used by
attached NL_Ports to validate their operating parameters with the local FL_Port after an initialization event has occurred. The
drive does not return a response to this ELS.
(Note: When operating as a private loop device, the drive will discard the FAN ELS request.)
