Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(2)
OL-25090-02
Caveats
This symptom might be seen when a switch is downgraded from Cisco NX-OS Release 5.1(x) or
Release 5.2(1) to NX-OS Release 4.2(x), and there is no Call Home configuration in the startup
configuration.
Workaround
: This issue is resolved.

Symptom
: The feature manager is not responsive and goes into a loop. As a result, interfaces cannot
be allocated to the storage VDC on a switch that is running the NPE image.
Workaround
: This issue is resolved.

Symptom
: A Cisco MDS 9000 switch that is configured for FICON Tape Acceleration (FTA) might
not correctly clear an existing FICON exchange if the proper sequence of Fibre Channel frames that
are needed to close the exchange are not seen. This situation can lead to a collision for a scheduled
slot and can cause the MSM-18/4 module to reload unexpectedly.
This symptom might be seen when a host or control unit does not properly close out an exchange
because of some error condition.
Workaround
: This issue is resolved.

Symptom
: A Cisco MDS 9000 switch that is configured for FICON Tape Acceleration (FTA) might
not account correctly for an acknowledged exchange that was previously accelerated. This situation
can cause the MSM-18/4 module to reload unexpectedly.
This symptom might be seen during times when the host is busy and it stacks the status from the
tape drive (control unit) until later when it requests status with a “request-status” message.
Workaround
: This issue is resolved.
