failing to move LUN between volumes with NDMPCOPY

PERSEUSDK

Hi guys,

I'm trying to move (actually copy) a LUN from one volume to another volume. However, it keeps failing as shown below.

NDCONN-NETAPP-C1> ndmpcopy -d /vol/VMFS_001/ESXI_BOOT_01 /vol/SAN_BOOT

The destination volume has adequate space.

Any ideas?

Do you have LUN with the same name on destination volume?

PERSEUSDK

Unfortunately no, the destination volume doesn't have a LUN with the same name.

UPDATE: It turned out, that a qtree had been created, which I didn't notice at all.

When I removed the qtree, the ndmpcopy worked as expected.

Thanks for all your answes

Good point...if the file exists then can use -f to overwrite.

scottgelb

This is odd.. can you ndmpcopy the entire volume to volume?  Does that fail?
