Patches and Fixes for this Version
15. Reference: SR #5003419424
zterm’s PT ommand is supposed to
change the ACC port configuration, but
it does not always work when checked
with zmntr.
TheMultiprotocol ACC Utilities Reference
Guide description was misleading. It is
revised to show the correct use of zterm’s
PT command, and zmntr is fixed to show
the port configuration correctly.
16. Reference: SR #5003437947
For NIO 8-port ACC cards, DMA
timeout was occurring during ACC
system start up in HP K-class systems
(and potentially any T series) with 2 or
more ACC cards installed. The problem
is faster to reproduce if 2 ACC cards
have failing ports and/or the ACC cards
are not numbered consecutively (0, 1, 2,
etc.) in the user’s ACC .answ file.
A synchronization error in the NIO 8-port
ACC firmware download processing has
been corrected.
17. Reference: TPO0h01179
Under high message loads on the
Z7300A and Z7330A 4-port E1/T1 cards,
the central processor utilization is
higher than expected.
The multi-message protocol used to
transfer messages to and from the card is
under-utilized, resulting in more driver
activity than is necessary. This is an
enhancement to introduce a delay in the
data transfers to and from the ACC
cards, to allow better advantage to be
taken of the multi-message protocol. The
default delay is 5 milliseconds, allowing
significant reduction in CPU utilization
and a minimal increase in message
latency. The default value is strongly
recommended. To configure the delay, use
the keyword datadelay
<value_in_ms> in the interface
definition section of the ttgen .answ file.
To override the delay, use datadelay 0.
