When restoring using a backup file that was exported from a different system, it is strongly recommended that you use a system that has the same hardware including fabric interconnects, servers, adapters and IOM or FEX connectivity. In case that there is a mismatch between the IOM/FEX links or servers on the two systems, you should acknowledge the chassis and/or servers accordingly after the restore operation. Mismatched hardware may lead to the restored system not fully functioning.

If the port is on a different ASIC, then the added link must be chassis-acknowledged. The link will automatically be added and lead to the symptom. The symptom will be seen after the acknowledgement. This occurs when the new link is added to same ASIC. When there is a single member port in a port channel, and an additional port is added to the fabric port channel, an HIF down event is triggered to accommodate the extra VNTAG space and provide extra VIF deployment.

You might have a modern environment with all sorts of high-tech equipment, but what makes it worthwhile is how you seamlessly bring together the presentation with audio, video and lighting. The ATEN Control System provides integrated control and system automation.

In very rare circumstances, an uplink on UCS-2208XP or 2204-XP may experience a rapid link up/down (less than 250 ms interval). This may result in the fabric interconnect side of the link being in link down state but the IOM side of the link being in an up state.

A number of users use soft or weak passwords and their password might be hacked with a dictionary based or brute-force attacks. Open the following file with an editor. The ‘pam_cracklib‘ module is available in PAM (Pluggable Authentication Modules) module stack which will force user to set strong passwords.

0 with QoS policies defined, critical errors will be displayed for all QoS policies and VIFs with QoS policies defined on them will be down after upgrading the subordinate interconnect but before upgrading the primary fabric interconnect. While upgrading to Cisco UCS Release 2. During this time all blades will lose their connectivity to both LAN and SAN. Expect that during the upgrade there will be a period of downtime between when the primary restarts and when the secondary becomes primary and brings up its VIFs.

Create a backup using the All Configuration option before upgrading. After importing the configuration file, reacknowledge all blades to restore their VIF status. If a problem occurs after the upgrade, restore the configuration using the backup file.

The Network Administration Tool (redhat-config-network) is an easy way to make changes to the various network interface configuration files (refer to the.

Bonding is nothing but Linux kernel feature . Finally, today I had implemented NIC bonding (bind both NIC so that it works as a single device).

When an earlier version of a management extension did not support a BIOS token, but a newer version of the management extensions supports that BIOS token, new tokens will now be displayed in the BIOS Defaults in the Cisco UCS Manager GUI and are deployed to the blade server.
