This section shows the steps needed to configure PowerMax iSCSI using a Solutions Enabler command line interface (SYMCLI). Solutions Enabler CLI is another way to configure PowerMax in addition to Unisphere.
- Create an IP interface for each iSCSI front-end interface on the PowerMax:
# symconfigure -sid 352 -cmd "create ip_interface dir 1e port 24, ip_address=192.168.209.3, ip_prefix=28,network_id=1,vlanid=0,mtu=9000;" commit -nop
A Configuration Change operation is in progress. Please wait...
Establishing a configuration change session...............Established.
Processing symmetrix 000197600352
Performing Access checks..................................Allowed.
Checking Device Reservations..............................Allowed.
Committing configuration changes..........................Started.
Committing configuration changes..........................Committed.
Terminating the configuration change session..............Done.
The configuration change session has successfully completed.
- Create a target for the port by specifying a director port and a network ID. Optionally specify the IQN for the target. If no IQN is specified, PowerMax generates one automatically:
# symconfigure -sid 352 -cmd "create iscsi_tgt dir 1e,network_id=1;" commit -nop

- Attach the IP interface with the target:
# symconfigure -sid 352 -cmd "attach ip_interface ip_address=192.168.209.3 to iscsi_tgt iqn=iqn.1992-04.com.emc:600009700bc724603bac01d500000003;" commit -nop

- Create a port group for iSCSI ports and add targets to the port group:
# symaccess -sid 352 -type port -name iscsi-pg create
# symaccess -sid 352 -type port -name iscsi-pg -iqn iqn.1992-04.com.emc:600009700bc724603bac01d500000003 add
- Create an initiator group for the host and add initiators to the group. The Initiator ID should match the IQN reported by the iSCSI initiator configuration on the Windows server:
# symaccess -sid 352 -type initiator -name i-dsib0162 create
# symaccess -sid 352 -type initiator -name i-dsib0162 -iscsi iqn.1991-05.com.microsoft:dsib1096 add
- Create a Masking View to present volumes to the host over iSCSI:
# symaccess -sid 352 create view -name iscsi-db -sg db_sg -pg iscsi-pg -ig i-dsib0162
- Configure CHAP Authentication (optional): The example here is to set up unidirectional CHAP where PowerMax authenticates the initiator. The value for
“-cred” must match the username in the host/initiator configuration file and
“-secret” to password. The “-iscsi” is set to the IQN of the initiator.
# symaccess -sid 352 -iscsi iqn.1991-05.com.microsoft:dsib1096 set chap -cred iqn.1991-05.com.microsoft:dsib1096 -secret SecretDsib1096
# symaccess -sid 352 -iscsi iqn.1991-05.com.microsoft:dsib1096 enable chap
