* multipathing to zFCP scsi devices using mdadm

The customer asks:

i just tried some multipathing to scsi devices attached to RHEL4U1,
I used mdadm to set up a multipath array. I made one disk fail, by removing
the path, using the z/VM console. After attaching the path again, i had to
toggle the path on again, using the chccwdev -e command and to echo the
values into the directories (or using script /sbin/zfcpconf.sh). But this
was creating a different devnode for the device.
I already worked with different rules defined in the rule files - but so
far without success.....do you have any idea ?
