Comment 6 for bug 1823200

VxFlex OS does not support multi-tenancy or per-volume authentication yet. We suggest to eliminate passing credentials from Cinder to Nova and storing them in “block_device_mapping” so that users won’t see any. Instead a separate file will be placed on each host. It will contain the same backend credentials parameters from similar sections in cinder.conf, e.g.

[vxflexos-1]
san_password = password1

[vxflexos-2]
san_password = password2
replication_san_password = replication_password2

Whenever Nova tries to connect a block device it will get the storage credentials from the file.
