On the OS6600, when we split the stacks into 2 or more substacks, an STR message of unauthorized CSM
socket may be seen on the current Primary Stack.
Workaround: Please ignore this message. If you are missing one of the messages, it will be retransmitted
and the system will be fine.

Synchronization of flash will fail if the elements are not running the same version of code.
Workaround: Only inserting the same version of software is supported. If this situation occurs, follow
the steps below to synchronize the flash to upgrade the stand alone unit to the same version before insert-
ing:
1. Separate the elements of the stack to form two stacks; each running the same release version.
2. Upgrade one of the two stacks to the same release version as the other.
3. Reconnect the two stacks together to reform the initial stack.

Changes made but not saved on a redundant CMM setup will not be reflected in the synchronization state
on the OS7000. The user may be unaware based on show running-directory that the NIs will all reset on
takeover.
Workaround: Changes in configuration should be saved and synchronized for redundant CMMs.
