Admin Displays LU as Available When It Really Is Not (163555)
The information in this article applies to:

This article was previously published under Q163555 SYMPTOMS
If a user closes an emulator session, the SNA Server Admin shows the
logical unit (LU) to be "Available" when it should show "SSCP" (in use).
CAUSE
When the emulator unbinds the LU-LU session, SNA Server solicits an UNBIND
from the host. The host can send an UNBIND (Bind Forthcoming - Byte1 of
BIND = '02'), promising that it will send a BIND in the future. SNA Server
responds positively to this, and waits for the BIND. However, the host
never sends a BIND as it had promised, so SNA Server marks this LU as on-
hold so that no unaccredited user can gain control of the LU in this window
of time. The status of the LU in the SNA Server Admin is SSCP. This is
normal.
However, if the emulator then terminates the SSCP-LU session by issuing a
Close SSCP request, SNA Server Admin then displays the LU as Available and
never sends a NOTIFY SLU disabled telling the host to disable the LU. The
user then considers the LU to be Available for use, when in fact it is not,
because SNA Server is still waiting for the BIND.
This problem is considered a host bug because it does not send the BIND
after promising to do so. However, SNA Server should handle this special
case.
RESOLUTION
To resolve this problem, obtain the hotfix mentioned below. In the hotfix,
SNA Server sends a NOTIFY SLU disabled, and displays SSCP in the SNA Server
Admin in this special condition.
STATUS
Microsoft has confirmed this to be a problem in Microsoft SNA Server
versions 2.11 and 2.11 Service Pack 1.
This problem was corrected in the latest Microsoft SNA Server 2.11 U.S.
Service Pack. For information on obtaining the service pack, query on the
