hpe_hba_cabling_check falsely issues a warning

After a routine update of a 6-node Nutanix cluster, a Nutanix Cluster Check (NCC) warning popped up indicating a problem with the SAS cabling. Running the check on the CLI offered some more details. Running : health_checks hardware_checks disk_checks hpe_hba_cabling_check [==================================================] 100% /health_checks/hardware_checks/disk_checks/hpe_hba_cabling_check [ WARN ] -----------------------------------------------------------------------------------------------------------------------------------------------------------+ Detailed information for hpe_hba_cabling_check: Node WARN: Disk cabling for disk(s) S6GLNG0T610113 are detected at incorrect location(s) 3:251:8 respectively where each value in the location corresponds to box:bay Node 10.

Is Nutanix the perfect fit for SMBs?

There’s a world below clouds and enterprise environments with thousands of VMs and hundered or thousands of hosts. A world that consists of maximal three hosts. I’m working with quite a few customers, that are using VMware vSphere Essentials Plus. Those environments consist typically of two or three hosts and something between 10 and 100 VMs. Just to mention it: I don’t have any VMware vSphere Essentials customer. I can’t see any benefit for buying these license.

Useful stuff about Nutanix

Nutanix was founded in 2009 and left the stealth mode in 2011. Their Virtual Computing Platform combines storage and computing resources in a building block scheme. Each appliance consists up to four nodes and local storage (SSD and rotating rust). At least three nodes are necessary to form a cluster. If you need more storage or compute resources, you can add more appliances, and thus nodes, to the cluster (scale out).
