I took a host(host 10) out of maintenence mode. Another host(host 14) vmotioned a couple of VMs to it. The vmotion process stopped progressing, and the following error was recorded on host 10: agent unable to save configuration to disk: Error syncing firmware configuration: vim.fault.TooManyWrites
The management agents later failed on host 14, and it lost connection to vcenter, plus the vmotion aborted. One of my co workers was able to get host 14 working again, after running
esxcfg-rescan vmhba32 and services.sh restart
Other VMs vmotioned okay to host 10, while two did not. what kind of issues can cause the vim.fault.toomanywrites condition?
Vcenter had the following suggestions:
Possible causes:
Cause: The agent cannot send heartbeats because of a networking related failure on host
Cause: The agent failed to update the configuration file on host
Cause: The agent failed to save the configuration file to disk on host
Cause: The provisioning module failed to load. As a result, all provisioning operations will fail on host.
ESXI version is 4.1.0, 260247
Any suggestions for checks appreciated.
