We are using ADM in a HA configuration and after a planned Failover of ADM was done to the secondary node in preparation for an upgrade of ADM. After the Failover one of the SDX's i.e. NSSDX07 reported to no longer be licensed and operating under the Grace licensing period. It appears that the SDX can still contact the ADM licensing server. The Grace period warning message appeared after logging directly into the SDX. The same warning can be seen on ADM under Networks->Licenses->Bandwidth Licenses->Pooled Capacity. This has been observed post the first failover. But now valid license is present on the SDX , not listed in ADM Refer to attached document with screen captures. Upgraded ADM from version 13.0.52.24 to 13.0.64.35

Problem Cause

Different SA dates for the licenses.
