You can access all the LUNs in the cluster by using the LUNs tab or you can access the LUNs specific to the SVM by clicking SVMs > LUNs.
Note: The LUNs tab is displayed only if you have enabled the FC/FCoE
and iSCSI licenses.
Creating LUNs
You can use Storage Manager to create a new volume and LUNs for an existing aggregate when there is available free space.
Deleting LUNs
You can use Storage Manager to delete LUNs and return the space used by the LUNs to their containing aggregates or volumes.
Creating initiator groups
You can use Storage Manager to create an initiator group. Initiator groups enable you to control host access to specific LUNs. You can use port sets to limit which LIFs an initiator can access.
Adding initiators
You can use Storage Manager to add initiators to an initiator group. An initiator provides access to a LUN when the initiator group that it belongs to is mapped to that LUN.
Cloning LUNs
LUN clones enable you to create multiple readable and writable copies of a LUN. You can use Storage Manager to create a temporary copy of a LUN for testing or to make a copy of your data available to additional users without providing them access to the production data.
Editing LUNs
You can use the LUN properties dialog box in Storage Manager to change the name, description, size, or the mapped initiator hosts of a LUN.
Moving LUNs
You can use Storage Manager to move a LUN from its containing volume to another volume or qtree within a storage virtual machine (SVM). You can move the LUN to a volume that is hosted on an aggregate containing high-performance disks, thereby improving the performance when accessing the LUN.
Editing initiator groups
You can use the Edit Initiator Group dialog box in Storage Manager to change the name of an existing initiator group and its operating system. You can add initiators to or remove initiators from the initiator group. You can also change the port set associated with the initiator group.
Viewing LUN information
You can use the LUN Management tab in Storage Manager to view details about a LUN, such as its name, status, size, and type.
Viewing initiator groups
You can use the Initiator Groups tab in Storage Manager to view all the initiator groups and the initiators mapped to these initiator groups, and the LUNs and LUN ID mapped to the initiator groups.
Understanding space reservations for LUNs
Understanding how the space reservation setting (combined with the volume guarantee) affects how space is set aside for LUNs helps you to understand the ramifications of disabling space reservations, and why certain combinations of LUN and volume settings are not useful.
Guidelines for using LUN multiprotocol type
The LUN multiprotocol type, or operating system type, specifies the operating system of the host accessing the LUN. It also determines the layout of data on the LUN, and the minimum and maximum size of the LUN.
Understanding LUN clones
LUN clones are writable, space-efficient clones of parent LUNs. Creating LUN clones is highly space-efficient and time-efficient because the cloning operation does not involve physically copying any data. Clones help in space storage utilization of the physical aggregate space.
Initiator hosts
Initiator hosts can access the LUNs mapped to them. When you map a LUN on a storage system to the igroup, you grant all the initiators in that group access to that LUN. If a host is not a member of an igroup that is mapped to a LUN, that host does not have access to the LUN.
igroup name
The igroup name is a case-sensitive name that must satisfy several requirements.
igroup type
The igroup type can be mixed type, iSCSI, or FC/FCoE.
igroup ostype
The ostype indicates the type of host operating system used by all of the initiators in the igroup. All initiators in an igroup must be of the same ostype. The ostypes of initiators are solaris, windows, xen, hyper_v, vmware, and linux.
