client IO.

Maintenance mode
Element 12.2 introduces maintenance mode, which enables you to take a storage node offline for maintenance
such as software upgrades or host repairs, while preventing a full sync of all data. If one or more nodes need
maintenance, you can minimize the I/O impact to the rest of the storage cluster by enabling maintenance mode
for those nodes before you begin. You can use maintenance mode with both appliance nodes as well as
SolidFire eSDS nodes.
Enhanced volume access security
You can now restrict volume access to certain initiators based on VLAN (virtual network) association. You can
associate new or existing initiators with one or more virtual networks, restricting that initiator to iSCSI targets
accessible via those virtual networks.
The following are updated Element API methods related to these security improvements (the Element API
Reference Guide has more information):

Fully Qualified Domain Name (FQDN) access to UIs
Element 12.2 supports cluster web interface access using FQDNs. On Element 12.2 storage clusters, if you
use the FQDN to access web user interfaces such as the Element web UI, per-node UI, or management node
UI, you must first add a storage cluster setting to identify the FQDN used by the cluster. This setting enables
the cluster to properly redirect a login session and facilitates better integration with external services like key
managers and identity providers for multi-factor authentication. This feature requires management services
version 2.15 or later. Learn more.
Storage node firmware updates
Element 12.2 includes firmware updates for storage nodes. Learn more.
Security enhancements
Element 12.2 resolves security vulnerabilities for storage nodes and the management node. Learn more about
these security enhancements.
New SMART warning for failing drives
Element 12.2 now performs periodic health checks on SolidFire appliance drives using SMART health data
from the drives. A drive that fails the SMART health check might be close to failure. If a drive fails the SMART
