Subject: [PATCH 42/43] lsluns: uninitialized value on adapter offline
|
||
|
|
|
||
|
|
Description: lsluns: uninitialized value on adapter offline.
|
||
|
|
Symptom: An error message is presented stating that some values
|
||
|
|
are not initialized while an operation is due.
|
||
|
|
Problem: The program execution is not reflection the offline adapter
|
||
|
|
status.
|
||
|
|
Solution: Account for offlined adapter status and show an appropriate
|
||
|
|
message.
