Opened: Mar 27, 2018
Severity: 4-Minor

Symptoms

A vCMP guest usually provides the vCMP host with some guest health statistics as a convenience to the vCMP host administrator. These stats are: -- mgmt/tm/sys/ha-status -- mgmt/tm/sys/software/status -- mgmt/tm/sys/software/provision These tables are created by the host when host vcmpd queries the guest over the vmchannel using REST. These RESTful queries may sometimes fail, causing the queried vCMP guest to be omitted in the display of the output of the following command: $ tmsh show vcmp guest

Impact

There is no functional impact to the guests or to the host, other than these lost tables. -- Some vCMP guests may not show up in the output of the following command: tmsh show vcmp health -- Some guests may appear with the wrong status in the GUI. Such as being grey when it should be green. -- Files containing guest information, kept in: /var/run/vcmpd/<guestname>/json/(sys-ha-status.json|sys-provision.json|sys-software.json) may be missing from that directory. -- There might be files present there named using the following structure: /var/run/vcmpd/<guestname>/json/sys-(ha-status|provision|software).json.bad.

Conditions

-- vCMP provisioned. -- Guests are deployed. -- Host vcmpd queries the guest over the vmchannel using REST.

Workaround

There is no workaround at this time.
