5.3 Understanding LUNs and Viewing
LUN Information
Each SM supports up to 64 FC logical unit numbers (LUNs), or 128 after a failover, that are numbered
zero through 63. There are three different types of LUNs: management (also called CAPI), EMP, and
partition. You can view information about each LUN, see section 5.3.1 on page 44.
The three types of LUNs have the following characteristics:
• Management (CAPI) LUN: Allows CAPI to configure the SM. Each SM can have a management
LUN. You only need to assign a management LUN if you are using CAPI to configure the SM over
a host port using SCSI protocol extensions. You are using CAPI only if your company has written a
program to monitor and manage the Galaxy 65 Subsystem. If you are not using CAPI, you can set
the management LUN to NONE. If you are using CAPI, you can set it to a value of 0-63.
Note Most UNIX, Linux, and Macintosh operating systems require that the management LUN be set to a higher
value than all array LUNs. Before creating your first array, change the management LUN to a higher
value. If you are using software that your company developed to configure and manage the controller (this
application uses CAPI to communicate with the controller), you must have a management LUN. If you are
not using software that your company developed, and therefore are not using CAPI, select NONE as the
management LUN. This allows your first array to be seen at LUN 0.
• EMP LUNs: Allow access to EMPs. You can set an EMP LUN to a value of 0-63 or NONE. NONE
means that the EMP cannot be accessed via a LUN. For information about changing the EMP LUN,
see Appendix Fsection F.2.1, ”Setting the EMP LUN”, on page 184.
•
Partition LUNs
: Allow access to array partitions on the Galaxy 65 Subsystem. You can set partition
LUNs to any numeric value from 0-63. For information about changing the partition LUN, see
3.4.3, ”Changing a Partition LUN”, on page 26.
