Publication Date:  2014-03-18 Views:  117 Downloads:  0
Issue Description
when using the tool to install the VRM, it will stop like the picture below and report that the communication is abnormal
Alarm Information
Handling Process
first, find the file /etc/sysconfig/network/routes, and add the gateway configuration in it. the content is as "default **.**.**.** - -", at the same time, configure the gateway IP on the access switch.
second, turn off the STP function by the command "stp disable"
at last, we can restart to install the fusion compute
Root Cause
first, we have to check the installation log file vrm.log, for this case, we found the information as below:
2014-03-12 16:31:48,687 {DEBUG} {com.huawei.cloudos.vrm.tool.StorageService 1043} DESCRIPTION: The communication between the host and the VRM is abnormal.
then, we will have to ckeck the factors as below:
1. we have to ensure that the firewall and anti-virus soft ware on your local PC have been turned off
2. we have to get through when doing the PING test from host to local PC
3. we have to configure the gateway on the host
4. we have to turn off the STP function on the access switch
at last, we find condition 3 and 4 does not exist at this moment, so we have to change it.
before installing the fusion compute system, we have to prepare all the basic network.
