Managing SAN Devices and I/O Multipathing in Oracle^® Solaris 11.4

How to Add Third-Party Devices

You can configure multipathing on third-party symmetric storage devices. In a symmetric storage device, all paths to the storage device are active and I/O commands can be issued through any path.

1. Become an administrator.

   For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.4.

2. Copy the /kernel/drv/scsi_vhci.conf file to the /etc/driver/drv/scsi_vhci.conf file.
3. Add the vendor ID and product ID entries to the /etc/driver/drv/scsi_vhci.conf file.

   The vendor ID and product ID are the vendor and product identification 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.

   scsi-vhci-failover-override =
   "VendorID1ProductID1", "f_sym",
   "VendorID2ProductID2", "f_sym",
   ...
   "VendorIDnProductIDn", "f_sym";
   

   ---

   Note -  The entries are separated by a comma (,) and the last vendor/product entry is terminated by a semicolon(;).

   ---

   For example, to add a device from a vendor ACME with a product ID of MSU and a device from vendor XYZ with a product ID of ABC, you must add the following lines to the /etc/driver/drv/scsi_vhci.conf file.

   scsi-vhci-failover-override =
   "ACME    MSU", "f_sym",
   "XYZ     ABC", "f_sym";

4. Save and exit the /etc/driver/drv/scsi_vhci.conf file.
5. Reboot the system.
