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.

SFTP disconnection seen post Unity Code Upgrade to OE 5.0.7 version

The file system is offline and requires recovery. This may be caused by the pool being offline. Fix the issue on the pool first. If the problem still exists, contact your service provider.

Critical alert: An I/O module in the Disk Processor Enclosure has faulted and must be replaced.

The I/O module is powered off. Try rebooting the Storage Processor (SP). If the I/O module remains powered off after a reboot, you may have to replace the I/O module. (Dell Correctable)
