LUN considerations for IBM iSeries hosts

This section describes LUN considerations for IBM^® iSeries™ hosts.

The storage unit creates logical unit numbers (LUN) that are nine characters. For example: 75-1409194, where 75 is the manufacturer, 14 is the logical subsystem, 09 is the volume, and 194 is the storage serial number (or WWNN)

Notes:

Fibre-channel attached LUNs are identified as the storage unit device type of 1750, on the IBM iSeries host system.
You can specify 1 - 32 LUNs for each attachment to an IBM iSeries fibre-channel adapter feature 2766, 2787, and 5760.

The following is an example of the output of the hardware service manager auxiliary storage hardware resource detail for the 2766 adapter. Similar information is displayed for the 2787 and 5760 adapters.
