vCenter Synchronization

When applying distributed VM group configuration changes, the switch will attempt to synchronize settings with the VMware vCenter for virtualization management. If the vCenter is unavailable, an error message will be displayed on the switch. Be sure to evaluate all error message and take the appropriate actions to ensure the expected changes are properly applied. If corrective actions are not taken, synchronization may remain incomplete when connection with the vCenter is restored.

Solution: When the switch connection with the vCenter is restored, use the following operational command to force synchronization:

>># /oper/virt/vmware/scan

Daylight Saving Time

For the Asia/Israel time zone, BLADEOS sets the end of Daylight Saving Time (DST) as the last week in September. However, because the observed end of DST varies according to the date of the Yom Kippur holiday in the Hebrew calendar since 2005, occurring on various Saturdays in September or October, the default DST rule may not work as desired.

For the Asia/Israel time zone, or any other time zone in which the start or end date of DST varies from year to year, the administrator should create a custom DST rule for those years in which DST is desired, but ends in a different week than the set by default.

Active MultiPath Protocol

For proper AMP operation, all access switches should be configured with a higher priority value (lower precedence) than the aggregators. Otherwise, unexpected AMP keep-alive packets may be forwarded from one aggregator switch to the other, even when its AMP group is disabled.
