An update to this query. Cindy did look into this for me, and found that: [i]I have confirmation that although the ZFS autoexpand property and supporting bugs like 475340 are in the Solaris 10 9/10 release, the supporting sd driver work to update the EFI label is not. In previous Solaris 10 releases, you could workaround the LUN expansion problem by either export/importing the pool or rebooting the system. My sense is that the integration of the autoexpand property is now restricting this workaround. We are considering how to resolve this but it might take some time.[/i]
So, at the end of the day I can make the LUN larger via my SAN managment interface, but the sd driver is unaware of this change so the EFI label never gets updated, meaning format continues to show the old size. I realise there are tricks with labelling under the format command using autoconfigure, but we wanted to avoid that non supported method. Also, as Cindy mentions, a zpool export/import fails to udpate the EFI label. Apparently this has worked in the past, although I'd never tried this. As a result, the best method to extend a zpool in our case is to create a second larger LUN and add it to the zpool to create a mirror, then detach the old smaller device. Then run zpool online -e to actually expand the zpool.
