Well, I had another task for today … I have an amount of FlexVolumes (sixty currently per controller), and I didn’t know if we had any, that didn’t have any LUNs on them. Now I thought there was a command for that since my co-worker mentioned something like that. However, once again … there isn’t.

Well, once again I was presented with a nice AutoSupport warning once I logged into my NOW account. Since we don’t have CIFS and/or NFS licensed on our filers, I wrote a cute little script that does the whole work for me.

The whole thing is surly based, that FTP is configured (as I described previously).
