how can we check the free space in SVM for a LUN .. I 've a 300G LUN and created several soft partitions on it but now i want to know how much i can grow .. i.e how much space is left on this 300G LUN

If lun is already created and mounted you cna use df -h or df -k to see the available space

metarecover -v -n metadevice -p

GNOM,

I got this error when i ran the said command

# metastat d109
