This protects system from hanging if RIO link fails or enters error
|
||
|
|
state. In some situations following maintenance read may initiate link
|
||
|
|
recovery from error state.
|
||
|
|
|
||
|
|
As it is now, MCheck mostly prevents system from hanging, but it also
|
||
|
|
adds sense to return status of maintenance read routine. I am using
|
||
|
|
return status in my new set of patches to check if RIO link is valid
|
||
|
|
during error recovery.
|
||
|
|
|
||
|
|
Alex.
