unable to deactivate proactive polling

[Serge Poitras]

Hello HP community,

We have a situation here that recently occured, which never did in the past, here are the facts;

we are trying to disable proactive polling on newly introduced Clariion luns in an existing environment...by "existing" I mean that we
Command:
# pvchange -p n /dev/dsk/c23t1d5

..returns:
pvchange: Physical volume "/dev/dsk/c23t1d5" could not be changed:
This may indicate that the kernel installed on this system lacks the neccessary functionality to perform this operation.

What makes this rather odd is that as stated above, we've added luns to this server in the past and were able to deactivate proactive polling, and the error message returned is somewhat vague as to "which functionality" may be missing ?

Environment:
rp3440
hp-ux 11.11
2 x 2Gb PCI/PCI-X Fibre Channel FC/GigE Dual Port Combo Adapter
LUNS are DGC CX3-80WDR5 (100gb luns)

Any insight on this odd behavior will be most welcome.

With best regards,
Serge

Does pvdisplay /dev/dsk/c23t1d5 show the (IMHO the annoying default) proactive polling on? Can you turn an old LUN from off to on? If it seems to be associated with only new LUNs, verify the Clariion presentation method for the LUNs, that it matches the working LUNs. Older arrays have special settings for HP-UX LUNs.

Typically this means you have installed the LVM commands path (PHCO_) without installing the co-requisite LVM kernel patch (PHKL_). If this box is up to dater on pathcing it suggests you have PHCO_35955 installed, but not PHKL_35970

Indeed, it seems that patches are required to add this functionality:

PHCO_35955 & PHKL_35970 with dep. PHKL_30607

Thank you both Bill and Duncan for your replies, points will be awarded
