Hi All,

Can someone let me know if they have seen the following problem and
what the resolution may be.

I am working with a customer running a Solaris8 (patch level 117350-43,
OBP 4.22.19) on a V880

Yesterday I removed two JNI FCE-6460-N Fibre cards (because Sun said
they would not work with MPXIO) and replaced them with two JNI
FCX-6562-L cards (which Sun said will work).

I also installed the latest JNI driver patch (114877-10).

However when I switched MPXIO on (mpxio-disable="no" in the
/kernel/drv/scsi_vhci.conf file) and rebooted, the system would panic
with the following message

Rebooting with command: boot

This leads me to believe that mpxio is conflicting with SDS.

I managed to get the machine up and running again via booting from
cdrom and disabling mpxio again.

Can anyone give me some help on this??

Thanks
