Remove snapshot without dataloss

ArjanA — Wed, 14 Mar 2012 14:39:23 GMT

Hi,

I have a P4300G2 with a volume that has a manual Point in Time snapshot on it.

The snapshot was created by another administrator when he demonstrated snapshots to someone in december 2010

I want to remove the snapshot without dataloss.

I have several questions:

1. How do I know what data is in the snapshot and what is on the real volume?

2. Which snapshot tasks should I perform?

Kind regards,

Arjan

Right click the snapshot, and choose delete snapshot. It will take a while for it to completely disappear.

Your data is actually a combination of this snapshot, and the "real" volume.

bryan is correct. You can delete using the CMC without any data loss. It will appear like it is gone immediately, but it may take a day or more before you see the available free space on the custer completely increased (and the consumed space decreased).

The deletion process can be IO intensive and I dont' think it can be throttled so you might want to wait to do this until you know you will have a lighter load on the system for a while... like starting friday night if your load goes light over the weekend.
