Fibre Channel Logical Unit Control Page - IBM Ultrium Internal Tape Drive T200 Reference Manual

The Enable EOD Generation flag should be set, since EOD generation is always
enabled.
The Buffer Size at Early Warning field should be 0, as this cannot be set.
The default value for the Select Data Compression Algorithm is 1 and indicates that
data compression is enabled. If Select Data Compression Algorithm is 0, the drive
uses Scheme 2 of the LTO-DC algorithm (passthrough mode). In the event that
Select Data Compression Algorithm does not agree with DCE of the Data
Compression Mode Page (see "Data Compression Mode Page" on page 31), the
DCE setting takes precedence.

There is one copy of this page for each initiator. This page is defined for
Fibre-Channel-attached devices only.
Enable Precise Delivery Control (EPDC), when set to 1B, enables checking of a
Fibre Channel Command Reference Number and ensures that the command
packets are delivered in order.
