A storage targe
t is a named iSCSI entity of configured LUNs.
The following c

• Recommended configuration sequence
• Targets

Recommended configuration sequence
MSA1510i configuration sequence is important — HP recommends the following sequence:
1. Create one or more portals for each storage port.
2. Create the storage LUNs and make note of the unit number assigned to each LUN.
3. Create one or more iSCSI targets.
4. Create portal groups for each target, assigning the available portals created in step 1.
5. Map the LUNs from step 2 to the targets. The number assigned in this step is the number that
the Initiator will present to its operating system.
NOTE:
The configuration sequence and procedures differ slightly when using the HP Storage Management Utility
(SMU) or the MSA Command Line Interface (MSA-CLI). For configuration details, see the HP Storage
Management Utility user guide or the MSA1510i Command Line Interface user guide. These and other
MSA1510i-specific user documents are provided on the MSA1510i Support CD, v2.0 or later, available on the
MSA1510i Support website: h
ttp://www.hp.com/suppport.
Targets
An iSCSI target is a named iSCSI entity, comprised of one or more confi gured storage LUNs. Up to 32
iSCSI targets can be confi gured on the MSA1510i. These virtual targets represent iSCSI nodes of the
MSA1510i.
Target names
Each target is accessed by its iSCSI node name. The name is a unique identifier that follows the
industry-standard iSCSI qualified name format known as "iqn". The MSA1510i automatically generates
worldwide-unique target names based on a unique factory-generated chassis ID and the reversed dotted
domain name of HP. HP strongly recommends using the system generated names for targets; however,
they may be changed to a user-defined name that meets the iqn naming requirements.
A changeable alias name is also assigned to each target. This alias is a shorter name that provides a
convenient reference string to help the target be more easily identified in the SMU and MSA-CLI.
Example system-assigned target node iqn name (with an alias of “target16”):
iqn.1986-03.com.hp.storage.msa1510i.p74280ax3qp02v.target16
For more information about iSCSI qualified names, see RFC 3270 on the Internet Engineering Task
Force website: h
