User`s guide

For example, the following entries disable multipathing on all FC HBA controller ports

except for the two specied ports:

mpxio-disable="yes";

name="fp" parent= "/pci@6,2000/SUNW,qlc@2" port=0 mpxio-disable="no";

name="fp" parent= "/pci@13,2000/pci@2/SUNW,qlc@5" port=0 mpxio-disable="no";

c. Add the following line for each FC HBA port that is to be disabled:

name="fp" parent= "parent name" port=port-number mpxio-disable="yes";

For example:

name="fp" parent= "/pci@6,2000/SUNW,qlc@2" port=0 mpxio-disable="yes";

Type stmsboot -u to start the reboot and conguration process.

You are prompted to reboot. During the reboot, the /etc/vfstab le and your dump device

conguration are updated to reect any device name changes.

(Optional) After the reboot, if necessary, congure your applications to use new device names as

described in

“Multipathing Considerations”on page 42.

Conguring Third-Party Storage Devices

Note – Before conguring any third-party device, ensure that they are supported. Refer to your

third-party user documentation, or third-party vendor for information on proper vendor and

product IDs, modes and various settings required for the device to work with multipathing

software.

Third-Party Device Conguration Considerations

Before you congure third-party devices for multipathing, be aware of the following:

■

The device must support the REPORT_LUNS SCSI command, and SCSI-3 INQUIRY command

VPD Device Identication Page (0x83).

■

You will need the vendor ID (VID) and product ID (PID) of the device. You can obtain

them by using the format command followed by the inquiry option on your system. See the

format(1M) man page.

When multipathing is enabled, the multipath access still depends on a device specic

scsi_vhci failover implementation accepting the device. The default way this occurs,

automatically, is for the scsi_vhci code to call a probe function in each failover

implementation, looking for the rst probe result that indicates the device is supported.
