Subject: [PATCH] libmultipath: fix detect alua corner case
|
||
|
|
|
||
|
|
If retain_attach_hw_handler = no, then the paths tpgs state will never
|
||
|
|
be checked, and the multipath device will always select the alua
|
||
|
|
handler, if no other handler is selected. the paths tpgs state
|
||
|
|
should be checked, regardless of the retain_hwhandler value.
