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

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
