A UUID is a 128-bit number assigned to every compute node on a network to identify the compute node globally. The UUID is denoted as 32 hexadecimal numbers. In the Cisco UCSM, a server UUID can be generated using the UUID suffix pool. The UCSM software generates a unique prefix to ensure that the generated compute node UUID is unique.
Operating systems including hypervisors and some applications may leverage UUID number binding. The UUIDs generated with a resource pool are portable. In case of a catastrophic failure of the compute node, the pooled UUID assigned through a service profile can be easily transferred to a replacement compute node without going through complex firmware upgrades.
The following are the steps to create UUIDs for blade servers:
- Log in to UCSM.
- Click on the Servers tab in the navigation pane.
- Click on the Pools tab and expand root.
- Right-click on UUID Suffix...
