7.4.4 Checking the status of servers and hosts after handling an error
This subsection explains how to check the status of servers and shared resources after an error has been resolved. For details about the commands explained here, see 9. Commands.
- Organization of this subsection
(1) Checking the system status
Checking the system status involves checking the status of monitoring paths, the reset path, and hosts and verifying that the active and standby systems can communicate with each other.
-
Checking the status of monitoring paths
You use the monitoring path status display command (monpath command) to check the status of monitoring paths and to locate a monitoring path failure on the basis of the monitoring path's IP address. You use this command when a failure has occurred on a monitoring path and when you recover such a failure.
-
Checking the status of the reset path (applicable if host reset is performed)
You execute the reset path status display command (monrp command). You use this command when a failure has occurred on a failure management processor or the reset path and when you recover such a failure.
-
Checking the host status
You use the server and host status display command (monshow -c command) to check the status of the local host (host that executed the command) and a remote host that is connected to the local host.
(2) Checking the server status
You use the server and host status display command (monshow command) to check the status of the servers running on the host that executed the command and their paired servers.
(3) Checking the resource server status
You use the server and host status display command (monshow -r command) to check the status of the resource server. You can also check the status of servers that use the resource server at the same time.
