The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter contains the following sections:
Storage pools—Name, description, RAID type (RAID 1/0, RAID-5, RAID-6), disks, and percentage of the full threshold
RAID groups—RAID group ID, RAID Type (RAID 1, 0, 3, or 5, disk, hot spare), expansion, or defragmentation priority, disks. You have options to automatically destroy a RAID group after the last LUN is unbound, and for power saving.
Host initiators—Add to new or existing host, hostname, WWN/IQN, SP port, initiator type (CLARiiON Open, HP Auto Trespass, HP No Auto Trespass, SGI, Fujitsu Siemens, Compaq Tru64), and failover mode (Active-Active mode -Failover Mode 4, Active-Passive mode (PNR)-Failover Mode 1, AIX Active-Passive mode (PAR)-Failover Mode 3, Legacy Failover Mode 2, Legacy Failover Mode 0). You add hosts to the storage groups.
Storage groups—Name
Logical unit numbers (LUNs)—Storage pool type (pool, RAID group), RAID type (1_0, 5), storage pool for new LUN (new or existing pool), user capacity, capacity units (MB, GB, TB, Blocks), alignment offset (LBA), default owner, initial tier placement (optimize for pool performance, highest available tier, lowest available tier), and options for automatically assigning LUN IDs as LUN names, LUN ID autogeneration, and Thin or Maximum provisioning. You mount LUNs as Datastores and also add them to the storage groups.
System Summary—File system allocation and system overview summary graphs
Data Movers—Unique ID, account name, server name, and role
Storage Processors—SP name, serial number, IP address, and faults (on or off)
Disk Devices—Unique ID, account name, name, disk type, state, capacity (GB), and other data
Hosts—Account name, hostname, IP address, storage group, attached to host (on or off), number of HBA ports, log in status, and status
Initiators—Account name, storage group, initiator name, log in status, SP port ID, SP port type, registered (y/n), hostname, and IP address
Ports—SP port, port IP address, port WWN, port type, storage processor, and fabric WWN
More Reports—Tabular report for RAID groups or hosts, and instant reports for file system allocation, as well as the top five storage capacity file systems, the top five file systems file count, and the top five storage capacity volumes

LUN dialog box, complete the following fields:
Storage Pool Type drop-down list
If you choose
RAID Group,
the system automatically generates the LUN ID. Automatic LUN naming ensures
that the LUN name conforms to a set of strict naming conventions. An
incorrectly named LUN no longer functions properly.
If you choose
Pool, the default path is set to automatically
assign LUN IDs as LUN names. However, you have the option to uncheck this
option (not recommended).
Automatically assign LUN IDs as LUN Names check box
If
you chose
Pool as the
storage pool type, the default path is set to automatically assign LUN IDs as
LUN names. However, you have the option to uncheck this option (not
recommended).
If
checked, LUN IDs are automatically assigned as LUN names.
Uncheck the check box if you do not want LUN IDs to be assigned
as LUN names.
Storage Pool for New LUN drop-down list
