I'm getting familiar with Netapp by using the simulator in my home lab with 9.4. Currently I have a 2 node cluster. I found the ontap 9 High Availability guide. Based on the instructions I have booted node 1 into Maintenance Mode. Now trying to run ha_config commands (ha_config show, ha_config modify controller ha-state etc.). It says "ha_config commands not supported on this configuration". Is it possible to run the simulator in HA mode to test the HA features out? I need to have a good understanding of how HA works. Thanks.
Thanks so much for your reply about page 6 of the Installation and setup guide for simulator. This perfectly answers my question - HA not available on simulator. I've seen the training from Flackbox and I love it. Problem is I need to learn the 9.4 GUI and all his current training is on 8x. I'm waiting for him to get out his 9x stuff.
You can run HA in ONTAP Select, which you can spin up in 90 day eval mode without a license. Get it from the evaluations section of the mysupport downloads page.
HA in ONTAP select uses a shared nothing storage model, so its a bit different architecturally than the shared disk model used in the hardware appliances, but it does support takeover/giveback operations and automated NDU workflows just like the hardware appliances do.
