Howdy All,
At the last FCP-4 working group meeting I presented a proposal to
request the use of continuously increasing SEQ_CNT (CISC) for Class 3
While most believe requiring continuously increasing SEQ_CNT for Class 3
service is a good idea, one vendor indicated that none of their
implementations support CISC, and another vendor was concerned about the
As such, we have the following options:
a. require CISC for Class 3 service. This means that existing
implementations can claim compliance to a prior standard (e.g., FCP-3);
b. specify that CISC should be used for Class 3 service;
c. no change (i.e., CISC is not required except for streamed Sequences).
My preference would be option a.
What say ye?
