How to rename Qtree in NetApp

To rename qtree in NetApp filers, we can follow below procedure.

• 1st make sure your volumes is in R/W state. If volume is snapmirrored and is in R/O mode... execute below procedure .

1. Quiesce snapmirror (snapmirror quiesce -S sourcefiler:/vol/vol1/qtree1 destfiler:/vol/vol1/qt1)
2. Break snapmirror  (snapmirror break destfile:/vol/vol1/qt1)
3. Now you can rename qtree, but not with ADMIN mode, we can do only in ADVANCED mode.
4. priv set advanced
5. qtree rename old qtree path  new atree path (qtree rename /vol/vol1/qt1 vol/vol1/qt2)
6. Once you rename qtree, make sure you also change share names.
7. Then you can resync snapmirror with source filer (snapmirror resync)

If qtrees belongs to volumes which are in specific vfilers, just add "vfiler run vfilername" before executing commands.
