|
|
|
|
- without HyperMetro:
|
|
vendor "HUAWEI"
|
|
product "XSG1"
|
|
path_grouping_policy multibus
|
|
no_path_retry 15
|
|
|
|
- with HyperMetro:
|
|
vendor "HUAWEI"
|
|
product "XSG1"
|
|
path_grouping_policy group_by_prio
|
|
prio alua
|
|
failback immediate
|
|
no_path_retry 15
|
|
|
|
ALUA is only used with HyperMetro(cluster of two arrays).
