I have various devices connected via ISCSI to Omnios: disks, tapes and media changer. I want to use MXIO for the disk devices but not for the tape and media changer device. I know that I can configure MPXIO for FC devices at port level in that kind:name="fp" parent="/pci@0,0/pci8086,2940@1c/pci1028,1f17@0" port=0 mpxio-disable="no"; there looks the physical path like /devices/pci@0,0/pci8086,2940@1c/pci1028,1f17@0/sd@0,0:c But for ISCSI devices the path looks like /devices/iscsi/[email protected] <mailto:[email protected]>%3Aoceanstor%3A2100a08cf8f6f36b%3A%3A1020003%3A172.xx.yy.zz000E,1:c How can I configure the MPXIO enable/disable per device for ISCSI devices?
You may work along the lines shown here: <https://docs.oracle.com/cd/E23824_01/html/821-1459/fncpc.html> On Iscsi, you configure multiple pathes via iscsiadm, and then mpathadm should show them, and mpxio takes care of them. You can selectively configure your pathes to exclude Tapes and media changers. In principle, this works on illunos, too, I've done this a decade ago while fiddling with iscsi boot (which essentially DOESN'T work!), I could configure multiple pathes, but abandoned that because it didn't work for the purpose (booting...). -- Dr.Udo Grabowski Inst.of Meteorology & Climate Research IMK-ASF-SAT https://www.imk-asf.kit.edu/english/sat.php KIT - Karlsruhe Institute of Technology https://www.kit.edu Postfach 3640,76021 Karlsruhe,Germany T:(+49)721 608-26026 F:-926026
