As you wrote the official doc is on Configipedia - Storage Systems Information - Configipedia - BMC Documentation
I quickly browsed the provided link and I feel that since Oracle ZS3-2 is a ZFS Storage Appliance, it might be supported via Oracle ZFS NAS Storage Systems - Configipedia - BMC Documentation.
Did not find anything for the other 3.
So can we conclude that the 3 storage devices - Dell EMC SC4020 , HP MSA 2040 ,
Oracle FS1-2 are not supported to be discovered by BMC Discovery 11.3?
And what is the remediation to this if these devices are not supported?
Andrew Waters Need your comment on this.
For network and storage devices discovery, when the doc does not tell you this is supported, then it is not. When a storage device is not supported you need to create a ticket with BMC customer support.
