Symptoms

Node is missing from the physical page view (VMK1 is disappearing automatically).

Cause

CIM agents are disabled on the node.
 

Resolution

  1. Ensure that wbem is enabled: esxcli system wbem get
  2. If wbem is disabled, enable it with the command: esxcli system wbem set enable true
  3. Check if all wbem providers are loaded: localcli system wbem provider list 
    [root@node1:] localcli system wbem provider list
Name              Enabled  Loaded
---------------------------------
sfcb_base         true     true
vmw_base          true     true
vmw_dcism         true     true
vmw_hdr           true     true
vmw_iodmProvider  true     true
vmw_kmodule       true     true
vmw_omc           true     true
vmw_pci           true     true
  4. If any wbem providers are not loaded, enable CIM agents (sfcbd-watchdog & wsman) using the below commands. 
    [root@vxrail-zone2-node-03:/opt/dell/srvadmin/iSM/bin] chkconfig sfcbd-watchdog
sfcbd-watchdog          off
[root@vxrail-zone2-node-03:/opt/dell/srvadmin/iSM/bin] chkconfig sfcbd-watchdog on
[root@vxrail-zone2-node-03:/opt/dell/srvadmin/iSM/bin] /etc/init.d/sfcbd-watchdog status
sfcbd is not running
[root@vxrail-zone2-node-03:/opt/dell/srvadmin/iSM/bin] /etc/init.d/sfcbd-watchdog start
sfcbd-init: Getting Exclusive access, please wait...
sfcbd-init: Exclusive access granted.
sfcbd-init: Request to start sfcbd-watchdog, pid 2111224

sfcbd-init: starting sfcbd
sfcbd-init: Waiting for sfcb to start up.
sfcbd-init: Program started normally.
[root@vxrail-zone2-node-03:/opt/dell/srvadmin/iSM/bin] /etc/init.d/sfcbd-watchdog status

[root@vxrail-zone2-node-03:/opt/dell/srvadmin/iSM/bin] chkconfig wsman
wsman                   off
[root@vxrail-zone2-node-03:/opt/dell/srvadmin/iSM/bin] /etc/init.d/wsman status
openwsmand is not running
[root@vxrail-zone2-node-03:/opt/dell/srvadmin/iSM/bin] /etc/init.d/wsman start
openwsmand: Getting Exclusive access, please wait...
openwsmand: Exclusive access granted.
openwsmand: Starting openwsmand
[root@vxrail-zone2-node-03:/opt/dell/srvadmin/iSM/bin] /etc/init.d/wsman status
openwsmand is running
[root@vxrail-zone2-node-03:/opt/dell/srvadmin/iSM/bin] chkconfig wsman
wsman                   off
[root@vxrail-zone2-node-03:/opt/dell/srvadmin/iSM/bin] chkconfig wsman on
  5. Verify vmk1 is created on the node now.
  6. Check the physical page, and the node is healthy.
