You can operate only the config_ha.sh, status_ha.sh, get_harole.sh, and query_fsw.sh scripts. Do not directly operate other scripts.

Application Examples of Common Scripts
- ./config_ha.sh -a
After running this script, the following information is displayed:
/ha/module/hacom/script # ./config_ha.sh -a HaMode: double HaLocalName: e99165d4-83e9-11ea-9734-60d75553af97(active) HaPeerName: 0d74b338-99ad-4ff7-897d-60d9b09d5ac0(standby) HaProtocol: ssl HaArbLk: 10.90.128.22:36800 -- 10.90.128.23:36800 HaSyncLk: 10.90.128.22:36802 -- 10.90.128.23:36802 HaRpcLk: 127.0.0.1:61806 HaArpLk: arpIpInfo Details: interface="eth0" netmask="255.255.255.0" activeArpIP="10.90.128.25" standbyArpIP="10.90.128.26" VLAN="" interface="eth0" netmask="255.255.255.0" VLAN="" interface="eth0" netmask="255.255.255.0" VLAN="" HaGwLk: 10.90.128.1When you run the ./config_ha.sh -a script, the status of the HaLocalName and HaPeerName roles may be NULL, --, active, or standby. The details are as follows:
- After dual hot backup is enabled on the active and standby nodes, the initial status of both the active and standby roles is NULL.
- After the active and standby roles are determined by arbitrated, active and standby are displayed respectively, for example, for the local node and peer node.
- If the heartbeat between the active and standby nodes is lost or no heartbeat has been set up (for example, only one HA is started), only the role of the local node is displayed, and the role of the peer node is displayed as --.
- ./config_ha.sh -h
You can run this script to view the help information about a large number of configuration naming rules. However, you are not advised to run it on the background to configure the HA. Because the HA configuration and validation process is complex, it is better to deliver the HA configurations through a WebUI.
Currently, you can run this script to query configuration-related operations (for example, run the config_ha.sh -a command). Do not run the config_ha.sh script to modify background data if you are not sure about the timely delivery and validation of the entire HA configurations.
After running this script, the following information is displayed:
