how do I resize a lun to fill out all the remaining space allowed?
lun maxsize /vol/voltest/voltest_qtr
Space available for a LUN of type: solaris, aix, hpux, linux, netware, vmware, openvms, xen, solaris_efi or image
Without snapshot reserve: 16353m (17147363328)
With snapshot reserve: no space
With complete snapshot reserve: no space
how do I use lun resize to automatically use all the remaining space?
Apparently, the volume has space for LUN expansion. Without and with snapshor reserve, you can expand the lun by 58041MB. With complete snapshot reserve, you can expand the LUN by 29020MB. The reason under the first two conditions you can expand the LUN by the same amount is because the volume's fractional reserve is set to 0.

I think your issue with lun expansion may be attributed to Qtree. What's the quota limit on the qtree? you may want to create a LUN on the volume (not qtree) and try lun resize.

you mean create another lun? My current lun is in use amd have virtual machines running on it. I want to be able to expand it.
If you can't create a new LUN, could you check the Qtree quota limit? Maybe you can expand that and then you may be able to expand the current LUN? Just a thought.
Thanks,

you can not increase the LUN size more than 10x times original.....example when you assign 10 gb to the lun originally you can grow the lun size max 100gb...not more than 100gb.
The 10x rule was posted in several places but also disproven in another post (was news to me too). From priv set advanced run "lun geometry" and you can see the max size you can grow the lun which will likely be more than 10x.
i also have same iissue:
is there any way that we can change this initial lun geometry without destroying and recreating lun
