I recently had an issue where I was unable to log in to the Unisphere GUI on the VPLEX, it would hang with the message “Retrieving Meta-Volume Information” after progressing about 30% on the progress bar.
This was caused by a hung Java process. In order to resolve it, you must restart the management server. This will not cause any disruption to hosts connected to the VPLEX.
To do this, run the following command:
ManagementServer:/> sudo /etc/init.d/VPlexManagementConsole restart
If this hangs or does not complete, you will need to run the top command to identify the PID for the java service:
admin@service:~>top Mem: 3920396k total, 2168748k used, 1751648k free, 29412k buffers Swap: 8388604k total, 54972k used, 8333632k free, 527732k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 26993 service 20 0 2824m 1.4g 23m S 14 36.3 18:58.31 java 4948 rabbitmq 20 0 122m 42m 1460 S 1 1.1 13118:32 beam.smp 1 root 20 0 10540 48 36 S 0 0.0 12:34.13 init
Once you’ve identified the PID for the java service, you can kill the process with the kill command, and then run the command to restart the management console again.
ManagementServer:/> sudo kill -9 8798
ManagementServer:/> sudo /etc/init.d/VPlexManagementConsole start
Once the management server restarts, you should be able to log in to the Unisphere for VPLEX GUI again.
