Provides the number of times the system chip has been reset. Typically,

chip has been operating properly.
Provides the connection state of the specified adapter. Possible values
include the following:
Ready to perform I/Os.
READY:
UPDATE: The topology is being re-discovered.
No connection.
DEAD:
Intermittent state, link temporarily down.
