Committing the iSCSI-related configuration

Saving current transactions

Use the iscsiCfg command to commit the iSCSI changes. The --commit all option triggers

propagation of the database to all iSCSI-capable platforms in the fabric and commits the changes.

To save the transactions

1. Connect to the switch and log in.

2. Enter the iscsiCfg

--commit all command as follows:

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.

3. To verify that the changes were committed, enter the iscsiCfg --show transaction command as

follows:

switch:admin> iscsicfg --show transaction

There is no active transaction

Resolving conflicts

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.

To resolve iSCSI-related configuration conflicts

1. Connect to the switch and log in.

2. Enter the iscsiCfg

--show fabric command as follows:

switch:admin> iscsicfg --show fabric

Aggregated iSCSI database state for fabric: Out of Sync

3. Verify the iSCSI configuration on each switch to find the switch that has the database you want

to use. On each switch enter the iscsiCfg

--show ddset command as follows:

switch:admin> iscsicfg --show ddset

Number of records found: 1

Name: ddset-engineering

State/Status: Enabled/Committed

Num. members: 1

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.
