To add a device from a “XYZ” vendor with a product ID of “ABC”, you would add:
device-type-scsi-options-list =
"ACME MSU", "enable-option",
"XYZ ABC", "enable-option";
enable-option = 0x1000000;
Save and exit the scsi_vhci.conf le.
Type stmsboot -u to start the reboot and conguration process.
You are prompted to reboot. During the reboot, the /etc/vfstab le and the dump
conguration are updated to reect the device name changes.
If necessary, perform device name updates as described in

Conguring Third-Party Storage Devices: Disabling
Devices
Multipathing can be disabled for all devices of a certain Vendor ID/Product ID combination
from Inquiry data. This exclusion is specied in the scsi_vhci.conf le.
▼
To Disable Third-Party Devices
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 identication 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", "disable-option",
"VendorID2ProductID2", "disable-option",
...
"VendorIDnProductIDn", "disable-option";
disable-option = 0x7000000;
The entries in the preceding example are separated by the ’,’ character and the last
vendor/product entry is terminated by the ’;’ character. For example, to add a device from
vendor “ACME” with a product ID of “MSU,” and a vendor device from vendor “XYZ” with
product ID “ABC,” you would add the following lines to the le /kernel/drv/scsi_vhci.conf:
device-type-scsi-options-list =
"ACME MSU", "disable-option",
