Troubleshooting
Problem
Network Services like SMTP and NTP no more functional after node startup. (As example after a power fail event) SMTP and NTP services may be not accessible at the same time because ethernet was not available during node startup, as the routing table was not set properly during that phase. The following events may occur and client will be unable to mark them as fixed: Error ID : 9150 : Unable to connect to the SMTP (e-mail) server Error Code : 2600 : Unable to connect to the SMTP (e-mail) server Error ID : 79501 : Failed to synchronize cluster time to NTP server
Resolving The Problem
Two options are possible to fix this problem.
Option A: Reset the cluster IP.
1. Write down the current IP settings (example is for IPv4)
###################################################################################
svcinfo lsclusterip
cluster_id cluster_name location port_id IP_address subnet_mask gateway IP_address_6 prefix_6 gateway_6
000002006502032E Cluster_Hotel local 1 10.10.10.23 255.255.240.0 10.10.10.24
000002006502032E Cluster_Hotel local 2
###################################################################################
2. Set the identical values with chclusterip
###################################################################################
svctask chclusterip -clusterip 10.10.10.23 -gw 10.10.10.24 -mask 255.255.240.0 -port 1
###################################################################################
Option B: Perform a config node fail over. (This action does not influence I/O.)
1. Check which node is the config node (config_node = yes)
Confirm both nodes are online and write down the panel_name of the config
node
################################
lsnodecanister
################################
2. Put the canister into service mode:
In this example the config node runs on Canister 2 (panel_name 01-2)
################################
satask startservice 01-2 -force
################################
Wait 2 minutes for the failover to complete.
Double-check it with:
################################
sainfo lsservicenodes
################################
3. Stop the service mode:
################################
satask stopservice 01-2
################################
Wait 2 minutes for the node to come back.
4. Check again that both nodes are active
