Hi All,

I installed vsim 9.12.1 to test few things, can anybody help me how i can capacity to aggregate as maxium i can is 56 disk of 1GB which gave total usable capacity of 39 GB.

I need atleast 200-300GB total aggregate capacity to do some testing ?? How can I do that.

I always use madlabber ansible script to create and configure ontap vsim. It allows me to set the disk_model to vscsi which allows you to set larger disks.

I hope this helps you!

Following thread also covers info regarding "using larger disk" such as 4GB/9GB (max 9GB). It's an older thread, but it should apply. I have simulator 9.10.1 and it allowed me to add additional two shelfs (2 comes pre-configured by default). I don't if there has been any changes in 9.12.1.

vsim_makedisks -h (In the disk-type list, numbered 31(4gb)&36(9gb) can give you additional larger space.

Give it a try: I am guessing if you add remaining two simulated shelfs (14 disks each) of disk type 36 , you will get to substantial aggr data size (Not sure if you get 200GB but something close to) . But, make sure you have the space to add such large disks.
