The isi_upgrade_logs -s command is used to view thecurrent upgrade stateof a Dell PowerScale cluster during an upgrade process. This command provides real-time status information about the upgrade's progress.
Understanding isi_upgrade_logs:
A utility in OneFS that displays logs and status information related to cluster upgrades.
Helps administrators monitor and troubleshoot the upgrade process.
Using the -s Option:
The -s flag stands for "status."
When used with isi_upgrade_logs, it displays the current state of the upgrade, including which nodes have been upgraded, which are pending, and any ongoing activities.
Information Provided by the Command:
Upgrade Phases:
Shows which phase the upgrade is in (e.g., pre-checks, package installation, post-checks).
Node Status:
Indicates the status of each node (e.g., upgraded, in progress, pending).
Overall Progress:
Provides percentage completion and estimated time remaining.
Why Other Options Are Less Suitable:
A. Post upgrade errors:
While isi_upgrade_logs can display errors, the -s option specifically shows the current state, not post-upgrade errors.
C. Active upgrade errors:
Error logs can be viewed using different options, such as isi_upgrade_logs -e, but -s focuses on status, not errors.
D. Upgrade assessment results:
Upgrade assessments are performed prior to the upgrade using tools like isi upgrade cluster assess.
Results are not viewed with isi_upgrade_logs -s.
Monitoring Upgrade Progress:
Regular Checks:
Administrators should regularly run isi_upgrade_logs -s during an upgrade to monitor progress and identify any issues early.
Example Output:
The command outputs a table or list detailing the status of each node and the overall upgrade progress.
