Fluid Cache License Is Expired
Possible Cause System settings such as changes to the system date cause the current Fluid Cache
license to expire. You can still access data on cached volumes, but performance is
degraded because the Fluid Cache cluster has been placed in maintenance mode
and caching is no longer active.
Solution Check the status of the license file by selecting the Fluid Cache cluster in
Enterprise Manager and referring to the status shown on the Events or Cache tabs.
If the license is expired, make sure that your system settings for date and time are
correct. If it is not correct, set the appropriate date and time. Take the Fluid Cache
cluster out of maintenance mode by selecting the cluster in Enterprise Manager,
clicking Edit Settings in the Summary tab, and then clearing the Maintenance
Mode option.
Possible Cause Fluid Cache for SAN is running on an evaluation license (typically 90 days) and that
time period has been exceeded. You can still access data on cached volumes, but
performance is degraded because the Fluid Cache cluster has been placed in
maintenance mode and caching is no longer active.
Solution Check the status of the license file by selecting the Fluid Cache cluster in
Enterprise Manager and referring to the license type shown on the Events or Cache
tabs. If the number of days remaining is zero, contact your Dell representative to
purchase a Fluid Cache for SAN license. After activating the new license, take the
Fluid Cache cluster out of maintenance mode by selecting the cluster in Enterprise
Manager, clicking Edit Settings in the Summary tab, and deselecting Maintenance
Mode.

ports, see Checking Network Connections. To check which ports are currently in
use, log in as a root user and run the command:
