- Organization of this subsection
- (1) When the number of displayed paths is less than the actual number of paths
- (2) When a system event occurs in the MSCS environment
(1) When the number of displayed paths is less than the actual number of paths
When displaying path information, the number of paths displayed might be less than the actual number of paths. This occurs when one host uses an LU exclusively, preventing other hosts from obtaining information about the devices in that LU. When this is resolved and the information can be obtained, the host can display all paths.
(2) When a system event occurs in the MSCS environment
When you start a standby node, or when a standby node has recovered from a path error, the following event is issued and output to the system event log. However, you can still perform operations as usual.
Source: mpio Event ID: 20 Description: A Path Verification request to a device on \Device\MPIODiskn that is controlled by Hdlm Device-Specific Module has failed. This may indicate a Path Failure.This event occurs when MPIO checks the disk before initializing it and the standby node cannot use the LU because the active node is using it.
