upgrade ontap software ndu on active/active cluster

[TDUBB1234]

I am about to upgrade from 8.0.1P3 7 mode  to 8.0.2P3 7 mode on 2 active/active clusters.

Went through auto support and I have upgraded the disk firmware.

I have uploaded the ontap software to

\\filer\c$\etc\software\802P3_q_image.tgz

all files are active at the moment using on fcp. no iscsi, cifs, or nfs sessions.

I will run

software update 802P3_q_image.tgz -r

on both nodes.

how do I ensure all luns remain online.

what step should i take next?

If all connected systems are using multipath connection and correctly configured for failover, you just do cf takeover/cf giveback on each head. Steps are provided in Data ONTAP upgrade guide as well as ASUP upgrade adviser.

Most settings to ensure that LUNs remain online should have been taken on connected hosts, not on filer.

Done.

What are the network configuration errors?

[aborzenkov]

You can ignore them. ha-config-check apparently was not updated to handle modern filers, including cluster interconnect.

[TDUBB1234]

just to test failover and failback. before I upgrade, how do I go that between 2 active filers?

[aborzenkov]

I do not understand this question. You do takeover/giveback between two systems in HA pair. What do you mean under "2 active filers"?

[TDUBB1234]

what i mean is a cluster. I got 2 filers in a cluster. I want to test the failover and failback functionality. how do i do this?

[aborzenkov]

Have you read "High availability configuration guide", in particular "Managing takeover and giveback" chapter? For version 7.x document is called "Active/Active configuration guide".
