HP 3PAR Solaris Implementation Guide

Oracle
Enabling SSTM/MPxIO Multipathing for Solaris 8 and 9
To enable SSTM globally for all HBAs in the system, edit the /kernel/drv/scsi_vhci.conf
file by changing the mpxio-disable parameter to a value of no.
mpxio-disable="no";
This step requires a host reboot.
For detailed installation instructions, consult the Solaris Fiber Channel and Storage Multipathing
Administration Guide.
Persistent Target Binding Considerations
Persistent target binding ensures that the mapping of a given target to a physical storage device
remains the same from one reboot to the next. In most cases, where each HBA port logically
connects to only one HP 3PAR StoreServ Storage port, it is not necessary to specifically implement
persistent target binding through configuration of the HBA driver since each initiator (Solaris host
HBA port) can only discover one target (HP 3PAR StoreServ Storage port) as shown in Figure 2
(page 35).
Figure 2 Persistent Target Binding
While the HP 3PAR StoreServ Storage is running, departing and returning HP 3PAR StoreServ
Storage ports (e.g., unplugged cable) are tracked by their World Wide Port Name (WWPN). The
WWPN of each HP 3PAR StoreServ Storage port is unique and constant which ensures correct
tracking of a port and its LUNs by the host HBA driver.
