[gpfsug-discuss] Bit of a rant about snapshot command syntax changes

[Sanchez, Paul]

The old syntax works unless have a colon in your snapshot names.  In that case, the portion before the first colon will be interpreted as a fileset name.  So if you use RFC 3339/ISO 8601 date/times, that’s a problem:

The syntax for creating and deleting snapshots goes from this:

mm{cr|del}snapshot fs100 SNAP at 2016-07-31T13:00:07Z –j 1000466

to this:

mm{cr|del}snapshot fs100 1000466:SNAP at 2016-07-31T13:00:07Z

If you are dealing with filesystem level snapshots then you just need a leading colon:

mm{cr|del}snapshot fs100 :SNAP at 2016-07-31T13:00:07Z

Thx
Paul

I think at least the most popular old forms still work, even if the documentation and usage messages were scrubbed.
So generally, for example, neither your scripts nor your fingers will break. ;-)

Why was mmdelsnapshot (and possibly other snapshot related commands) changed from:

Mmdelsnapshot device snapshotname –j filesetname

TO

Mmdelsnapshot device filesetname:snapshotname

..between 4.2.0 and 4.2.1?

It’s mildly irritating to say the least!
