So for example, if you create an aggregate with 32 600GB SAS drives, ONTAP will automatically create 2 raid groups of 16.&nbsp; If you then add 10 more drives (best practice is a full raid group at a time though) it will automatically create a new 3rd raid group with those 10 drives.&nbsp; Then if you add 22 more, it will fill out the 3rd raid group to 16 (from 10) and create a 4th raid group of 16 automatically.&nbsp; You can also change the default raid size and also add drives manually to existing raid groups, or force creation of a new raid group.&nbsp; ONTAP is flexible to do almost anything you want (within the aggr and rg size limits) but the automatic volume management to create new raid groups works well.</P><P></P><P>You could test with both System Manager (GUI) and the command line "aggr create" and "agg add" command to learn the syntax.&nbsp; Some only use System Manager which works well, but if you want to do some things like add to an existing raid group, learning the cli is good to know.</P></BODY></HTML> Mon, 17 Sep 2012 19:52:22 GMT https://community.netapp.com/t5/ONTAP-Discussions/how-to-create-Raid-Groups-and-add-them-to-an-aggregare/m-p/7827#M1741 scottgelb 2012-09-17T19:52:22Z Re: how to create Raid Groups and add them to an aggregare ?? https://community.netapp.com/t5/ONTAP-Discussions/how-to-create-Raid-Groups-and-add-them-to-an-aggregare/m-p/7836#M1746 <HTML><HEAD></HEAD><BODY><P>Thanks Scott for the wonderful explanation .</P><P></P><P>What command can be used to check the raid group status of the aggregate ? and Where plex comes into the picture ?</P></BODY></HTML> Mon, 17 Sep 2012 19:59:11 GMT https://community.netapp.com/t5/ONTAP-Discussions/how-to-create-Raid-Groups-and-add-them-to-an-aggregare/m-p/7836#M1746 SANJEEVROHILA 2012-09-17T19:59:11Z Re: how to create Raid Groups and add them to an aggregare ?? https://community.netapp.com/t5/ONTAP-Discussions/how-to-create-Raid-Groups-and-add-them-to-an-aggregare/m-p/7841#M1748 <HTML><HEAD></HEAD><BODY><P>The easiest way is "sysconfig -V". Uppercase V for a summary disk count per aggr and raid group. Or the GUI representation in the oncommand software. You can also run "aggr status -r" r the equivalent "sysconfig -r" to get raid groups and spares in detail. </P><P></P><P>Sent from my iPhone 4S</P></BODY></HTML> Mon, 17 Sep 2012 20:04:06 GMT https://community.netapp.com/t5/ONTAP-Discussions/how-to-create-Raid-Groups-and-add-them-to-an-aggregare/m-p/7841#M1748 scottgelb 2012-09-17T20:04:06Z Re: how to create Raid Groups and add them to an aggregare ?? https://community.netapp.com/t5/ONTAP-Discussions/how-to-create-Raid-Groups-and-add-them-to-an-aggregare/m-p/7849#M1750 <HTML><HEAD></HEAD><BODY><P>Plex is when you run syncmirror. Pool0 and pool1 to ensure spares go to the right pool so that syncmirror plexes (disks) stay on separate loops/stacks for redundancy. </P><P></P><P>Sent from my iPhone 4S</P></BODY></HTML> Mon, 17 Sep 2012 20:05:18 GMT https://community.netapp.com/t5/ONTAP-Discussions/how-to-create-Raid-Groups-and-add-them-to-an-aggregare/m-p/7849#M1750 scottgelb 2012-09-17T20:05:18Z Re: how to create Raid Groups and add them to an aggregare ?? https://community.netapp.com/t5/ONTAP-Discussions/how-to-create-Raid-Groups-and-add-them-to-an-aggregare/m-p/7854#M1752 <HTML><HEAD></HEAD><BODY><P>Awesome Scott..</P></BODY></HTML> Mon, 17 Sep 2012 20:10:13 GMT https://community.netapp.com/t5/ONTAP-Discussions/how-to-create-Raid-Groups-and-add-them-to-an-aggregare/m-p/7854#M1752 SANJEEVROHILA 2012-09-17T20:10:13Z
