Thanks for your input - actually I had forgotten about the zoning and the new space *was* coming from a different NetAPP. However my storage guy did *not* forget. Plus, as a troubleshooting step he added a new LUN from a NetAPP that was already connected to the server. No luck. Also got another server (did I mention this earlier) that is in the same zoning-group, same OS levels and it could get a new LUN with no problem. So it really seems isolated to this one server. (Which really just makes no sense to me...)
Well, think of it like that: having found out what was NOT the culprit is a step forward, no? ;-)
First off, i suppose you also have checked that the device the disk is supposed to be attached to is also working - if you have all your other NetApp disks attached to FC adapter A and the new one to adapter B then adapter B might be the problem.
I have no experience with the NetApp drivers but maye something is wrong with the ODM entries concerning the device(s). You may try a
rmdev -Rdl on the adapter and then a rediscovery via
cfgmgr to rebuild that. Notice that to
completely clean the ODM you need to
varyoffvg all the volume groups consisting of disks coming from the adapter you are deleting. If they are still online they will hold at least one FC connection (i.e one hdisk device if the driver is multipath enabled) open.
I hope this helps.

vxpfto(1M) vxpfto(1M)
NAME
vxpfto - set Powerfail Timeout (pfto)
SYNOPSIS
vxpfto -g diskgroup -t timeout
vxpfto [-g diskgroup] -t timeout volume_list
vxpfto [-g diskgroup] -o pftostate={enabled|disabled}
vxpfto [-g diskgroup] -o pftostate={enabled|disabled} volume_list
DESCRIPTION
Powerfail Timeout is an attribute of a SCSI disk connected to an HP-UX host (see the pfto(7) man page). The vxpfto command sets the Power-
fail Timeout interval on a set of Volume Manager disks, either all disks in a disk group, or all disks underlying the volumes listed.
The first form of the command sets the same PFTO value for all the disks in the specified VxVM diskgroup.
In the second form, all disks underlying the given list of volumes are selected, optionally restricted by the disk group specified with the
-g option. If you specify a diskgroup, any volume in the list not belonging to the diskgroup is ignored.
Use the -o pftostate option to disable or enable PFTO. By default, PFTO is enabled. You can enable PFTO either on all disks in a disk
group, or on all disks underlying the volumes listed.
If you invoke vxpfto without arguments, it displays a usage message.
OPTIONS
-g diskgroup
Specifies the disk group for the operation, either by disk group ID or by disk group name.
-o pftostate={enabled|disabled}
Enables or disables the use of PFTO for IO.
-t timeout
Specifies the PFTO value in seconds. The value must be zero or a positive integer. Zero represents the system default PFTO
value. The default value depends on the disk driver controlling the disk device.
volume_list
A list of VxVM volume names. List items must be separated by white-space.
EXIT CODES
vxpfto returns a zero if successful. If it encounters an error, vxpfto exits and displays a message on standard error. Defined exit codes
are:
0 Success.
1 No PFTO value specified.
2 No diskgroup or volume list specified.
3 Illegal PFTO value specified.
EXAMPLES
Set the PFTO value on all disks in disk group testdg to 100 seconds:
vxpfto -t 100 -g testdg
Set the PFTO value to 50 seconds on all disks underlying volume01 and volume02 in disk group testdg:
vxpfto -t 50 -g testdg volume01 volume02
Set the PFTO value to 300 seconds on all disks underlying volume01 and volume02, even though they are not in the same disk group:
vxpfto -t 300 volume01 volume02
Disable PFTO on all disks in disk group testdg:
vxpfto -g testdg -o pftostate=disabled
Enable PFTO on all disks underlying volume01 and volume02i in disk group testdg:
vxpfto -g testdg -o pftostate=enabled volume01 volume02
