Resolving conflicts between iSCSI configurations When you merge two fabrics with different iSCSI configurations, a conflict will result. If there is a conflict, the database will not be merged and you must resolve the conflict. The iscsiCfg --show fabric command displays the "out of sync" state. The rest of the switches will function normally, however, since there is no segmentation of E_Ports as a result of discovery domain set database conflicts. 1. Connect to the switch and log in. 2. Enter the iscsiCfg --show fabric command to display the "out of sync" state: switch:admin> iscsicfg --show fabric Switch IDSwitch WWN 220 10:00:00:05:1e:36:0d:f8 * 1 10:00:00:60:69:e0:01:56 Switch State iSNSC Out of Sync Disabled - Disabled Aggregated iSCSI database state for fabric: Out of Sync 3. On each switch enter the iscsiCfg --show ddset command to find the switch that has the database you want to use: switch:admin> iscsicfg --show ddset Number of records found: 1 Name: ddset-engineering State/Status: Enabled/Committed Num. members: 1 4. Enter the iscsiCfg --commit all command with the -f option on the switch with the database you want to use fabric-wide: switch:admin> iscsicfg --commit all -f This will commit ALL database changes made to all iSCSI switches in fabric. This could be a long-running operation. Continue (yes, y, no, n) [n]: y The operation completed successfully. 5. Enter the iscsiCfg --show fabric command to verify that the conflict has been resolved: switch:admin> iscsicfg --show fabric Switch IDSwitch WWN 220 10:00:00:05:1e:36:0d:f8 * 1 10:00:00:60:69:e0:01:56 Switch State iSNSC In Sync Disabled -- Disabled Aggregated iSCSI database state for fabric: In Sync LUN masking considerations The node WWN and port WWN of the local switch are used to query LUNs on the physical target. If the physical target uses LUN masking to control access, these WWNs must be added to the LUN masking to ensure that the LUN query returns the LUNs to the switch. You can obtain these WWNs in either of two ways: • Enter the iscsiCfg --easycreate tgt command with the -s option to return the node and port WWNs of the switch. The following is an example. switch:admin> iscsicfg --easycreate tgt -s The following WWNs will be used for any easycreate operation from this switch: Node WWN: 10:00:00:60:69:80:04:4a Port WWN: 21:fd:00:60:69:80:04:4a 270 iSCSI Gateway services
