Re: online lun resize 11.31

it doesn't surprise me that everything started working when you deactivated the vg and ran the diskinfo... in this case the device would have been completely closed and the call to diskinfo would have accessed the LUN again for the first time.

What is supposed to happen for an "online" resize operation is that according to SCSI standards the device is supposed to respond with Unit Attention (ASC/ASCQ: 0x2A/0x9 = capacity data changed) on the next IO after the lun capacity is changed. This causes the IO stack to do a reopen detect increased capacity.

Whether the SVSP _does_ respond with the correct Unit Attention message I don't know (I know some NetApp systems don't do this and that the EVA and XP _do_ work correctly). You could ask your support contacts for some clarity on this...
