Subject: [PATCH] libmultipath: unset detect_checker for clariion / Unity
|
|
|
6605ee |
arrays
|
|
|

|
|
|

Dell EMC would like to always use the emc_clariion checker. Currently
|
|
|
6605ee |
detect_checker will switch the checker to TUR for Unity arrays.
|
|
|
6605ee |
This can cause problems on some setups with replicated Unity LUNs,
|
|
|
6605ee |
which are handled correctly the the emc_checker, but not the TUR
|
|
|
6605ee |
checker.
