You may experience the issue where your cluster has been degraded and there's a failed CE. In the Grid system (version 5), the Cluster will be degraded if one of the Cache Engines fails.
To solve this issue please create a support ticket. And on of our agents will help you out.
1) Login to management server with SSH
2) Change to root privilege with "su" command
3) Login to pang-cli
4) Show the systemid
5) Enter enable mode
Note: use the systemid (*1234567) as password
6) Check System Status
Cluster state: r-degraded Server Slot Status Operational state Device state Administrative state ce-1 powered on enabled started unlocked ce-2 N/A N/A stopped N/A ce-3 powered on enabled started unlocked ce-4 powered on enabled started unlocked
CE-2 status is N/A
7) Exist from pang-cli
Note: In the following steps CE-2 is an example, you should replace it with the failed CE number)
8) Try to ping the failed CE, for example, if it was CE-2, try to ping it and the BMC of CE-2 from the management server (BMC IP is the iDRAC IP of CE-2)
9) In this case, both pings fail, contact the customer's onsite engineer and let him remove the power cord and power supply from CE-2, then wait 5 mins and put them back and power on the machine
10) Try to ping both BMC and CE-2 from the management server again.
11) After ping is replied, Login to pang-cli (follow above step 3 to 5) and start the service on CE-2
#oper server 2 #start
12) Verify the service status
13) Verify the service status from UBview
To check the log on iDRAC of the failed CE and find out why it happens, launch the vnc session in the management server and connect the management server with vncviewer.
Click Continue if you get an Encryption warning pop-up message
Input the Root Access password for the Management Server
After connecting to the management server with vncviewer, enter "opera" command to launch the opera browser
On the Browser, open the failed CE iDRAC (in this example CE-2).
Login to IDRAC with root user and password
Check the system vents log and verify the issue.
