White Paper
5. Next, tell MPxIO driver to accept the device based on the SCSI vendor and
Product-ID by editing /kernel/drv/scsi_vhci.conf file. Add the following settings
in the tail of the file.
# vi /kernel/drv/scsi_vhci.conf
...
device-type-scsi-options-list=
“Qsan P210C”, “symmetric-option”; // 4 spaces must be kept
// between Qsan and
symmetric-option = x01000000; // P210C
In order to find out the SCSI vendor and Product-ID, use format command and
select one of the instances in device.
format> inquiry
Vendor: Qsan
Product: P210C
Revision: 1.0.
Beware that the MPxIO driver accepts the vendor name as 8 character-words
only. So the vendor name must be added 4 spaces at the end of “Qsan” in
/kernel/drv/scsi_vhci.conf file.
6. A reboot is necessary to let all settings validate.
# reboot -- -r
7. After rebooting, these iSCSI disks will be merged to one MPIO device.
# format // Before MPxIO applied,
// OS detects the
sameSearching for disks... // LUN as two independent
// disks.
