Committing the iSCSI-related configuration After you have configured iSCSI-related configuration parameters, including iSCSI VTs, discovery domains, discovery domain sets, and CHAP authentication, after they have been defined, you must save them through a commit process. Each set of changes, additions, and deletions is called a "transaction." Review the current transaction before committing the changes; once the changes are committed, they are enforced fabric-wide. The commit process option triggers propagation of the database to all iSCSI-capable platforms in the fabric and commits the changes. IMPORTANT: Make all necessary changes to the database-VT creation, LUN additions, DD creation, DDSet creation, and so on-before issuing the iscsiCfg --commit all command. 1. Connect and log in to the switch. 2. Enter the iscsiCfg --show transaction command to display the pending transactions: switch:admin> iscsicfg --show transaction Active transaction ID is: 10490 and the owner is: CLI. The following groups have been modified: 1. Auth. group. 2. Target/LUN group. 3. DD/DDSet group. 3. Enter the iscsiCfg --commit all command to save the transactions: switch:admin> iscsicfg --commit all 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. 4. Enter the iscsiCfg --show transaction command to verify that the changes were committed: switch:admin> iscsicfg --show transaction There is no active transaction 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 322 iSCSI gateway service
