Goal

How to install IDR and what is an IDR and why is it needed

IDR a Interim Diagnostic Relief

Interim: Until official version with fix is released.
Diagnostic: Option of providing additional bits for debugging.
Relief: Implies customer is in need for a solution

Why is it needed

Urgent need to provide relief to customer. (hours not days or weeks)

1. Issue happens frequently and is more than just a nuisance.
2. Situation impacts production
3. Customer can't wait for minor or micro release.

What has been changed

1. Till 3.4.2 an IDR was provided as binary fix / T-Patch
2. Starting with 2011.1 a full new binary release build is compiled for each new IDR
3. Installed IDRs are listed as IDR in BUI/CLI in section Maintenance -> System -> "Available Updates"
4. In the BUI the IDR rev/branch is now clearly displayed with a different color
5. At the CLI you see an asterisk in front of the release number as here:                                     
   *[email protected],1-2.11.3.1 ( [*] : Interim Diagnostics and Relief (IDR) )

Installing an IDR

How to install the IDR since 2011.1.x

If the IDR is of the form *.pkg.gz, it is a complete installation and should be installed using the process in

How to install the IDR till 3.4.2

To install a binary fix a so called hidden workflow is used to replace file by file, which means that the relief is installed file by file. If the IDR consists of 6 files you need to run the workflow 6 times, for each file once. The hidden workflows are displayed by navigating to Maintenance -> Workflow, hold shift-key and click on the "+" sign next to Workflows on the headline.

The workflow to install a binary relief is called "Temporary patch" and might be listed on the second page of the available workflows.

Example:

In this example the following files will be replaced by files provided through an IDR.

To apply files binary fix ( procedure till 3.4.2) , navigate in the BUI to

click "+" while holding down the SHIFT key. This will reveal a number of hidden workflows. The workflow to install an IDR is listed on the second page of
the workflow list which is available by clicking on the ">>" symbol just below the WORKFLOWS tab.

Look for a workflow called "Temporary patch" and a click on it will bring up a form requesting

Start by pressing the "BROWSE" button for the "New file" property, then navigate throug the local filesystem and select the "kernel/drv/zfs" file. At this
point an "UPLOAD" button will appear, click this and wait for the file to be uploaded. Then complete the rest of the form with:

In the "Path..." box enter the path- and filename of the binary to be replaced:

then press "apply". The workflow will now perform the necessary steps to replace the original binary with the one containing the fix and will backup the original file. The "zfs" module requires these steps to be repeated for the 64bit version of the driver. Upload the file "kernel/drv/amd64/zfs" and provide the correct path to the original binary in the "Path..." box:

The example shows that for 2 files you need to repeat the necessary steps two times. The workflow can only replace file by file and and needs to be executed for every file provided in an IDR.

Now reboot the system as last step of the IDR installation.



Once booted, confirm the module is active by logging in to the ZFSSA and run "confirm shell"
