User`s guide

A probe implementation determines support based on some combination of scsi_inquiry(9S)

data. A device with INQUIRY data indicating T10 Target-Port-Group-Support (TPGS)

compliance will use the standards-based TPGS failover implementation. For noncompliant

devices, a failover implementation's probe will typically determine support based on VID/PID

match against a private compiled-in table.

To override the probe process, the scsi_vhci.conf le supports a

scsi-vhci-failover-override property. The value of scsi-vhci-failover-override can be

used to establish support for a device not currently accepted by probe, override probe support,

or disable multipath support for a device.

Conguring Third-Party Storage Devices: New Devices

Multipathing can be congured on third-party symmetric storage devices. A symmetric storage

device is dened as a storage device in which all paths to the storage device are active and I/O

commands can be issued through any path.

▼

To Congure New Third-Party Devices

Perform the following steps to congure third-party devices if your system already has

multipathing enabled. If your system has multipathing disabled, you can congure third-party

devices while enabling multipathing as described earlier in this chapter.

Add the vendor ID and product ID entries to the /kernel/drv/scsi_vhci.conf le.

The vendor ID and product ID are the vendor and product identication strings that the device

returns in SCSI INQUIRY data. The vendor ID must be eight characters long. You must specify

all eight characters even if the trailing characters are spaces.

The product ID can be up to 16 characters long.

device-type-scsi-options-list =

"VendorID1ProductID1", "enable-option",

"VendorID2ProductID2", "enable-option",

...

"VendorIDnProductIDn", "enable-option";

enable-option = 0x1000000;

Note that the entries are separated by the ’,’ character and the last vendor/product entry is

terminated by the ’;’ character.

For example, to add a device from a “ACME” vendor with a product ID of “MSU”, and to add a

device from vendor “XYZ” vendor with a product ID of “ABC”, you would add the following

lines to le /kernel/drv/scsi_vhci.conf:
