Upon Dell EMC Unity Code upgrade from 4.x.x to 5.x.x, certain drives running C342 FW can be exposed to drive unavailability due to firmware issue.

A dial home test message is sent via ConnectHome.

When a Unity system initiates a call home to open a service request for a support issue, it sends the customer's contact information along with the alert message. This simplifies the process for Technical Support engineers to contact the appropriate individuals. Up-to-date contact information ensures that Technical Support has the most accurate information for contacting the customer in response to a support issue. Dell Technologies recommends keeping the primary contact's information up to date in Unity Unisphere. This article shows how to do so.

Issue: Changing attribute access to a host like read-only, R/W, or root, sends an error of having a duplicate host in the list.

Unity supports the ability to host multiple tenants on a single system for service providers who would like to isolate group of VLANs from the rest, also tenants helps admins as NAS servers belonging to same tenant will have the tenant's name visible beside each NAS server which eases the NAS servers grouping and classification. NAS servers created with access to the tenant will have access to the VLANs included in the tenant. Dell Unity’s flexible pool-based architecture also enables the ability to separate each tenant onto their own pools for separation at the drive level, if necessary.
