* Copy OneFS Install File:
* Obtain the appropriate OneFS installation tarball (.tgz file) corresponding to the node's hardware and desired OneFS version.
* Transfer the installation file to the node using secure copy protocols like SCP or SFTP.
* The file can be placed in a directory such as /ifs/data/Isilon_Support/.
* Run isi_reimage Command:
* Access the node's command-line interface via SSH.
* Execute the reimage command with the path to the installation file:
isi_reimage <path_to_install_file>
* For example:
isi_reimage /ifs/data/Isilon_Support/OneFS_vX.X.X.tgz
* The command will initiate the reimaging process, unpacking the installation file and reinstalling OneFS.
* Benefits of This Method:
* No External Media Required:
* Eliminates the need for a USB flash drive or CD/DVD media.
* Efficient Process:
* Directly utilizes the node's capabilities to perform the reimage.
* Remote Execution:
* Can be performed remotely without physical access to the node.
* Considerations:
* Data Backup:
* Ensure that any necessary data is backed up, as reimaging will erase existing data on the node.
* Cluster Membership:
* If the node is part of a cluster, properly remove it from the cluster before reimaging to prevent cluster inconsistencies.
