Due to some temporary parallel cabling, VxVM 5.0 began to use two paths to a 3510 disk array:
# vxdmpadm getsubpaths
NAME STATE[A] PATH-TYPE[M] DMPNODENAME ENCLR-NAME CTLR ATTRS
================================================================================
c2t40d2s2 ENABLED(A) - c2t40d2s2 sun35100 c2 -
c6t44d2s2 DISABLED - c2t40d2s2 sun35100 c6 -
On c6, the storage array is no longer present and we are going to attach an other storage array on that port - which may conflict with the current layout known by VxDMP.
How could I remove this path from Veritas' DMP control?
luxadm probe printout:
# luxadm probe
No Network Array enclosures found in /dev/es
Found Fibre Channel device(s):

It seems that dmpnodes (pseudo devices representing a collection of paths to a specific physical device) can not be deleted. Server restart cleans the dmpnode list.
