This chapter provides information to help you troubleshoot common problems that may occur during the Cisco HyperFlexupgrade process.
Upgrade Button Missing in Cisco HX Data Platform
If the upgrade button is missing in the Cisco HX Data PlatformObjects tab, under the Actions drop-down list:
Try using a different browser with the latest version of flash.
Firefox browser is not supported due to an outdated version of flash that is bundled with the browser. Manual update of flash
within Firefox is possible, but the recommendation is to use either Chrome or Internet Explorer with a modern version of flash.
Try restarting VMware vCenter.
Cluster Start Command Error: Node Not Available
After an offline upgrade, due to a VMware EAM issue, sometimes all the controller VMs do not restart. The stcli start cluster command returns an error: Node not available.
Action: Manually power on the controller VMs, then start the storage cluster.
Manually power on the controller VMs.
Login to the vSphere Web Client.
Locate the controller VMs that are not powered on.
From the Navigator select, vCenter Inventory Lists > Virtual Machines > vm.
Storage controller VMs, have the prefix, stCtlVM.
From the right-click or Actions menu select, Power > Power On.
Repeat until all the storage controller VMs are powered on.
Restart the storage cluster.
Login to the command line of any controller VM.
Run the command.
# stcli cluster start
A Node Fails to Upgrade due to vCenter Issues
Sometimes during an online upgrade the vCenter daemon crashes on a node. When this happens, the node cannot enter HX maintenance
mode. Without entering HX maintenance mode, the node cannot complete the upgrade. All other nodes, with properly functioning
vCenter, complete the upgrade.
