We have an HA pair running 7.3.4 P2. We want to upgrade the Ontap version to 7.3.7.
The issue is one of the the filer is serving data to Vmware, Exchange and SQL.
Is there anyway we can do the upgrade non disruptively?
If a NDU is not possible then what is the best way to do it?
Do we have to shutdown all the VMs and what need to be done in terms of exchange and SQL?
If it's a HA pair you should be able to do NDU. All LUNs in the HA pair are available on all ports in the HA pair , hence when you perform the takeover, partner system assumes responsibility for the failed system's LUNs without interruption. Only the 'session-oriented' services will be disrupted such as cifs, ndmp, http, ftp etc.. I suggest you run the Upgrade Advisor, it is an online tool, available on the NOW site, simplifies the process of planning Data ONTAP upgrades. It's not something that you should follow blindly, but it's a good starting point for your to begin the process.
Thanks for the quick reply.
Due to some reason my filer is not showing in the Netapp support site (We have valid support contract and Netapp are looking into it) and I am not able to run the Upgrade Advisor for that.
Is there any test I can perform prior to the upgrade to make sure the upgrade won't hamper the vmware datastore, exchange and SQL ones?
I would recommend running upgrade advisor. I am not an expert on upgrades, but I can give you some pointers as to what you can do prior to running the upgrade.
Note: The values in the CPU and Disk Util columns are strongly recommended not to exceed 50% for all ten measurements reported. Ensure that no additional load is added to the storage system until the upgrade completes.
Save this output file for a couple of weeks after the upgrade is complete
This way you have configruration report before the upgrade, which could be handy when troubleshooting issues related to upgrade. I hope this helps.
As I said I am not an expert....but hope this helps.
