Symmetrix Fibre Channel with Qlogic HBAs on UnixWare 7
Arbitrated Loop Configurations
Example:
The above example shows a typical target and bus reservation for the
QLA2200. In the example, controller number 2 sees 35 Symmetrix
devices. 32 device are assigned to target 0 and 3 devices are assigned
to target 1. Target numbers are reassigned by SCO regardless of the
LUN number scheme assigned by the Symmetrix.
The EMC-approved driver supports multiple HBA instances. The
operating system assigns each QLA2200 HBA instance a controller
number (0 through 7) based on the PCI slot that contains the HBA.
The QLA2200 driver supports 8 busses per HBA, 32 targets per HBA
and 32 LUNs per target.
