SUMMARY: Netapp takeover issue

I finally found that /kernel/drv/lpfc.conf was misconfigured. Parameter
nodev-holdio was set to 1 instead of 0:

# If set, nodev-holdio will hold all I/O errors on devices that
disappear
# until they come back. Default is 0, return errors with
no-device-delay.
nodev-holdio=0;

Original question:

> Hi,
> I just installed a Netapp cluster 3020 and wanted to present some LUNs

> 4.1 MP1 and an Emulex 9002L. The filers and the host are attached to a
> McData switch and properly zoned. I was able to create a VM volume and
> a filesystem. The host sees both pathes:

> Multipathing information:.
> numpaths:   2
> c3t0d0s2        state=enabled   type=secondary
> c3t1d0s2        state=enabled   type=primary
>
> I tested the failover on the filer, and the host was not able to use
> the secondary path. Commands like ls, touch, format, devfsadm, vxdisk
> hang, but the machine is still up and running.
