Symmetrix Fibre Channel with Qlogic HBAs on UnixWare 7
Fabric Configurations
Never write data to disk 0.
• P is the fdisk partition number. P can range from 0 through 4. The
p0 node corresponds to the whole disk, and the p1 to p4 nodes
correspond to partitions displayed by the fdisk command.
Either during boot time, in the var/adm/log/osmlog, or if the
command /sbin/sdiconfig -l is issued, disks under UnixWare 7 are
represented as shown in the following example.
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.
