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

skipping system dump - no dump device configured
rebooting...
Resetting ...

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

try reconfiguration boot

boot -r

Do you boot from SAN?

Seems like the boot disks have also MPxIO enabled. With MPxIO enabled the
disks get new device paths, but these aren't (yet) available.
Try disabling MPxIO on a per adapter basis (see the manual page for fp(7d))

Is stmsboot(1M) already available in Solaris 8? I just have Solaris 10
systems here at reference. If stmsboot is there you could try to
call "stmsboot -e" instead of editing scsi_vhci.conf directly.

Hey Daniel, nope boot disks are internal, but being a V880 also have
dual paths so may be part of the cause. will look into enabling mpxio
just for the san disks. not sure about stmsboot, but doubt it as sun
not developing sol8 anymore, thanks. rob
