Does solaris metadevices support clariion MetaLUN expansion?

Hi gurus!

Last week i made a LUN expansion (concat MetaLUN) on a clariion cx4-240.

The target is a Solaris 10u9, and i previously configured "auto configure" at format level (type 0) on it, so the OS already see the new size.

And here comes the problem:

I have Solaris Volume Manager (metadevices) "over" the LUN, so my real device (the one that I mount) is a metadevice (dev/md/dsk/dx) that cannot see the new size.

I tried with growfs (no changes)

i tried with devfsadm (no changes)

what can i do??

thanks!
