You can test the communication for an external path by performing a login test for an iSCSI target on an external storage system.
If the login test fails,
revise the settings of the iSCSI target so that you can log in, or delete the iSCSI
target. If any iSCSI targets to which you cannot log in are registered, an attempt is
made to connect to these iSCSI targets when you access an external volume, and load is
applied to the storage system or network. This might cause operations to
fail.
- The external iSCSI targets must be registered.
- Check the iSCSI port to use for external connections.
- Check the following information about the external storage system containing
the volume to use for the quorum disk:
- Name of the iSCSI target
- IP address
