Method used to troubleshoot the failure of scanning for LUNs
Method used to troubleshoot the failure of scanning for LUNs: 1. Ensure that the network connection is correct. 2. On iSCSI networks, ensure that networks are normal and ping packets are not lost. 3. On Fibre Channel networks, ensure that the rate of ports on the host and array complies with the negotiated one. 4. Check whether configurations on the host and array are correct, including the mapping and initiator configurations. 5. On iSCSI networks, if the version of the host initiator is early, update the initiator software. 6. Check whether the array enters the DFT mode. 7. After the AIX host connects to Fibre Channel cables, to scan for LUNs successfully, you need to restart the host. 8. In SUSE 10 and SUSE 10 SP1, to scan for LUNs successfully, you need to update the iSCSI initiator. 9. If you encounter any other faults, contact technical support engineers.
