Troubleshoot upload phase when running scripts on hosts

Overcome the PowerFlex Gateway not being able to upload files using the "Run script on host" feature.

About this task

If the "Upload" phase fails with a timeout error, check if the following appears in the scaleio.log file on the PowerFlex Gateway, and the LIA log file of the relevant node. If the error appears, follow the remediation steps listed below. This issue is caused by a lack of resources in the PowerFlex Gateway's operating system, and in the JAVA process sustaining the upload.

Typical scaleio.log file: 

2020-07-30 11:35:28,333 [executor-23] INFO  c.e.s.s.d.i.c.UploadFileCommand - activating serial upload force algorithm due to upload of package UploadFileCommand[9.20.25.23, 9.20.125.23] that has failed due to memory problem java.lang.OutOfMemoryError: Java heap space

Steps

  1. Check if the PowerFlex Gateway's operating system has sufficient memory: minimum 8 GiB, recommended 12 GiB.
    • In case of SVM this requires shutdown of the SVM to modify the memory
    • This can be done at any time as long as no gateway orchestration is running
    • If "Run Script on Host" is running abort the operation prior to shutdown of the OS
  2. After adding memory we need to increase the Java settings:
    1. Using file editor (such as vi) open the file: /opt/emc/scaleio/gateway/bin/setenv.sh and modify the following line:
      From: 
      CATALINA_OPTS="-Xms128m -Xmx2048m"
      To: 
      CATALINA_OPTS="-Xms128m -Xmx4096m"
    2. Restart the gateway service:
      Linux: 
      systemctl scaleio-gateway restart
      Windows: Restart the service from the services.msc window.
  3. Log in to the PowerFlex Gateway, and run the "Run Script on Host" feature with upload capability again.
