HP StorageWorks SAN Director Installation Guide (A7393-90009, May 2007)

Installing the optional B-Series iSCSI Director Blade154

domain set can be created/defined but only one can be enabled at any point in time. The

active/enabled discovery domain set will be enforced across all the switches in the fabric.

When you execute commit, the switch on which the command is executed will become the master

and will merge the discovery domain database to the rest of the IP-aware switches. Then use

iscsicfg show fabric to verify the database merge.

--disable ] ddset [-n DD Set name] [–d DD_Names] args

NOTE: If there is a conflict, then the database on the rest of the switches will be overridden by the

database on the current switch (which initiated the merger) and intervention is needed to clear the

conflict. However, the rest of the switches will function normally. There is no segmentation of

E_Ports when the discovery domain set database conflicts.

To create a discovery domain set, use the iscsicfg --create ddset command with the -n and -d

operands:

An explicit enable operation needs to be done to enable the discovery domain set. To enable the

newly created DDSet, use the following command:

Defining CHAP entries for iSCSI device authentication

The modify command can be used only for changing the authentication method for a target from

None to CHAP or CHAP to None. If nothing is specified, no authentication method is enforced. If

CHAP is specified, then either one-way or mutual CHAP enforcement will be performed based on

the login frame from host.

iscsicfg < --create | --show | --modify | --delete | --clear > auth

[-u username] [–s CHAP_Secret] args

To modify the authentication method for a target, use the iscsicfg --modify command as

follows:

switch:admin> iscsicfg --create ddset -n myddset -d mydd,mynewdd

Operation Succeeded

switch:admin> iscsicfg –-enable ddset –n myddset

Operation Succeeded
