Isilon: How to Manually Restart Failed Process After Maintenance Due to Incorrect Restart

A process may fail to start automatically after a maintenance activity.

The following alert may be noticed:

Event : Process <Process Name> of service <Service Name> has failed to restart after multiple attempts

Example:
Process isi_healthcheck of service isi_healthcheck has failed to restart after multiple attempts

Usually, the process restarts automatically. In case a process does not restart automatically, manually restarting the process typically resolves the issue.

Verify if the process is running or not:

1. Open an SSH connection on any node in the cluster and log in using the "root" account
2. Check if the process is now running on the node where the error message was shown.

# isi_for_array -n <Node Numeber> 'ps auxwww | grep -i <Process name> | grep -v grep'
Where <Node Number> is the Node on which the process is not running.

# isi_for_array -n1 'ps auxwww | grep isi_healthcheck | grep -v grep'

If the process IS Running:

1. Get the group ID using the following command:

# isi event groups list

2. Clear the alert:

# isi event groups modify --resolved=yes --ignore=yes --id=<Group ID from Step #1>

If the process IS NOT Running:

Depending on the process, the exact procedure for restarting a process can vary. Contact Dell Technical Support if assistance is needed manually restarting the process.
