That is really a good description of what to do, but ... What about the situation of building a new raid on the same volume. Can I set the raid size to 13, build another raid with the 36 GB drives onto the same volume, change the raid size to 14, add one more 36 GB drive to that raid set, then add 13 more 36 GB drives to another raid set on the same volume?
Yes. Whenever you change the raidsize on a volume (did I mention that it is a per-volume setting?) it applies to the the current raid group and any future raid groups (unless you change it again). If you set the raidsize below the size of the current raid group it will only mean that the next two disks added will create a new raid group.
I've got four shelves of 18 GB drives in two raid sets of 14 and 13 with one spare. I want to add two raid sets of 14 and 13 of the 36 GB drives with one spare for that group. ... All in the same volume. also, the four new shelves are the new ones that can handle the 36 GB drives. The result is a spare for each of the 18 and 36 drives and full shelves.
If the current raid group (that is, the one with the highest number) has QTY 13 of the 18GB disks, you could use something like this:
netapp> vol options vol0 raidsize 13 netapp> vol add vol0 2@36 (Or "vol add vol0 -d diskid1 diskid2) netapp> vol options vol0 raidsize 14 netapp> vol add vol0 12@36 (Or "vol add vol0 -d diskid3 ... diskid14) netapp> vol options vol0 raidsize 13 netapp> vol add vol0 13@36 (Or "vol add vol0 -d diskid15 ... diskid27)
Of course, you should contact your SE or NetApp tech support for assistance with this. They will probably give you something like the above.
Good luck!
