Method to automatically determine host to LUN (logical unit number) path availability for multi path attached storage systems

The present disclosure provides testing of a storage system. The test may compare the storage array controller LUNs which may be configured to be accessible by a host with the LUNs which are currently available to prevent a zero path scenario from occurring. The test may verify at least one path exi...

More Information
Summary:The present disclosure provides testing of a storage system. The test may compare the storage array controller LUNs which may be configured to be accessible by a host with the LUNs which are currently available to prevent a zero path scenario from occurring. The test may verify at least one path exists for each LUN to a storage controller of a storage array before injecting an error into another storage controller of the storage array. The present disclosure also provides verification of the configuration of a storage system. The configuration verification may verify that the storage array controller LUNs which are configured to be accessible by a host are actually accessible by the host. If the configuration verification is unable to verify the configuration of storage system, the configuration verification may display an error.
