Multiple SnapMirror scheduals for the same volume

CCIE17603 — Thu, 05 Jun 2025 06:21:26 GMT

Is there a way to create multiple snapmirror scheduals for the same mirrored volume? I need to create a sched for Mon - Friday 8AM-5PM every 5 min = 1024KB of bandwidth. On Sat-Sun (for the same volume) every 5 min all day long = 2048KB of bandwidth

.. is this possible, or can you only have 1 schedual per volume.?I noticed that if you use System Manager it only shows 1 schedual per volume even if I put multiple scheudals in the etc/snapmirror.conf file.

FILER-1:NAS-VOL FILER-2:NAS-VOL_SnapMirror kbs=1024 00,05,10,15,20,25,30,35,40,45,50,55 8,9,10,11,12,13,14,15,16,17 * 1,2,3,4,5

FILER-1:NAS-VOL FILER-2:NAS-VOL_SnapMirror kbs=2024 00,05,10,15,20,25,30,35,40,45,50,55 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23 * 0,6

Something like this:

Thanks everyone.

IMHO is not good idea

Yes, it is possible. I never used System Manager for this so cannot comment on its behavior. Just edit /etc/snapmirror.conf manually.

But you may want to open support case because this sounds more like a bug in System Manager.

BTW you could use "*/5" meaning "every five minutes"; it would make entry shorter and more readable.

..yeah I usually go back and forth from cmd line, to editing files under /etc & using System Manager so it was just something that I noticed when I looked in the GUI. On a side note I was at customer who was using the NetApp plug-in for VCenter and they had a SnapMirror schedule that they configured from VCenter and System Manager said that the schedule compatible with it, so it couldn't show it through the GUI. I just thought that was interesting. On a side note I did end up opening a ticket and apparently you can configure multiple schedules. (See the link below)

Not much info here so I guess it's just trial and error.
