And add recommended no_path_retry and pgfailback values.
Info from:
- RHEL https://download.huawei.com/edownload/e/download.do?actionFlag=download&nid=EDOC1100113070&partNo=6001&mid=SUPE_DOC&_t=1612885511000
- SLES https://download.huawei.com/edownload/e/download.do?actionFlag=download&nid=EDOC1100117892&partNo=6001&mid=SUPE_DOC&_t=1612885538000
- 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).
