Sorry if this is a stupid question - can you not physically check?
Even if you need to shutdown the Appliance.
I found this 5220 disk replacement doc : https://www.veritas.com/content/support/en_US/doc/ka6j00000004IHvAAM
Not a stupid question. Site didn't want to shut down unit but we have tasked them to open box. I had also found that procedure but I'm not looking to replace the array drives, we need to replace the 2 internal HDs. And now as I check email, looks like they have identified them. Thx
