Thankyou for that, but could you instead send the output from "prtconf -v" or "prtpicl -v" - the -pv output doesn't show any of your attached disks. >>> I've also tried to disable MPxIO for internal disks so in my mpt.conf I >>> have: >>> >>> mpxio-disable="no"; name="mpt" >>> parent="/[EMAIL PROTECTED],0/pci8086,[EMAIL PROTECTED]/pci1000,[EMAIL >>> PROTECTED]" unit-address="0" mpxio-disable="yes"; >>> >>> Unfortunately local disks are still under MPxIO and 2530's LUNs are not. >>> >>> I changed mpt.conf to: mpxio-disable="no"; #name="mpt" >>> parent="/[EMAIL PROTECTED],0/pci8086,[EMAIL PROTECTED]/pci1000,[EMAIL >>> PROTECTED]" unit-address="0" mpxio-disable="yes"; > >> name="mpt" parent="/[EMAIL PROTECTED],0/pci8086,[EMAIL PROTECTED]" > unit-address="0" > JCM> mpxio-disable="yes"; >>> and this time local disks are no longer under MPxIO but neither are >>> 2530's luns.

Sorry, I misread your stanza. You should in fact have tape="sctp"; ddi-vhci-class="scsi_vhci"; name="mpt" parent="/[EMAIL PROTECTED],0/pci8086,[EMAIL PROTECTED]/pci1000,3150" unit-address="0" mpxio-disable="yes"; mpxio-disable="no"; note the parent=... part. >>> I have a similar config on v490/SPARC with 2530 and it works (however >>> there are other issues). >>> >>> Any idea how to get MPxIO with 2530 on x4150 on S10U4 to work? > > JCM> It really should be just a case of > JCM> - add the relevant patches, > JCM> - reboot > JCM> - run "stmsboot -e" > > > Usually it is. On SPARC with -10 it was just that. > Here I got -14 - maybe that's a problem? I don't think so. There was a problem with -10 if you had an mpt-attached DVD or tape drive, so we respun it and eventually ended up releasing the -14 rev. James C.
