+nvme-seagate-vs-smart-add-log(1)
+================================
+
+NAME
+----
+nvme-seagate-vs-smart-add-log - Retrieve Seagate vendor specific extended-SMART
+Information
+
+SYNOPSIS
+--------
+[verse]
+'nvme seagate vs-smart-add-log <device> [OPTIONS]'
+
+DESCRIPTION
+-----------
+For the NVMe device given, sends the Seagate vendor log
+request and either saves the result to a file or dumps the content to stdout.
+
+The <device> parameter is mandatory and may be either the NVMe
+character device (ex: /dev/nvme0), or a namespace block device (ex:
+/dev/nvme0n1).
+
+The log contents may be associated with the controller, in which case the namespace parameter is ignored.
+
+Two logs exist, page 0xC4 (Extended SMART log page) and page 0xCF (DRAM Supercap SMART log page)
+
+This command will only work on Seagate devices supporting this feature.  Not
+all commands work across all product families.
+
+OPTIONS
+-------
+-l <NUM>::
+--log=<NUM>::
+        Log number, page 0xC4 (Extended SMART log page) and page 0xCF (DRAM
+        Supercap SMART log page)
+
+-n <NUM>::
+--namespace-id=<NUM>::
+        Namespace number
+
+-o <FILE>::
+--output-file=<FILE>::
+        Output in binary format. Defaults to text-formatted dump to stdout
+
+EXAMPLES
+--------
+Get the vendor specific extended SMART information for the specified device.

+## How to contribute
+
+There are two ways to send code changes to the project. The first one
+is by sending the changes to linux-nvme@lists.infradead.org. The
+second one is by posting a pull request on github. In both cases
+please follow the Linux contributions guidelines as documented in
+
+https://docs.kernel.org/process/submitting-patches.html#
+
+That means the changes should be a clean series (no merges should be
+present in a github PR for example) and every commit should build.
+
+See also https://opensource.com/article/19/7/create-pull-request-github
+
+### How to cleanup your series before creating PR
+
+This example here assumes, the changes are in a branch called
+fix-something, which branched away from master in the past. In the
+meantime the upstream project has changed, hence the fix-something
+branch is not based on the current HEAD. Before posting the PR, the
+branch should be rebased on the current HEAD and retest everything.
+
+For example rebasing can be done by following steps
+
+```shell
+# Update master branch
+#   upstream == https://github.com/linux-nvme/nvme-cli.git
+$ git switch master
+$ git fetch --all
+$ git reset --hard upstream/master
+
+# Make sure all dependencies are up to date and make a sanity build
+$ meson subprojects update
+$ ninja -C .build
+
+# Go back to the fix-something branch
+$ git switch fix-something
+
+# Rebase it to the current HEAD
+$ git rebase master
+[fixup all merge conflicts]
+[retest]
+
+# Push your changes to github and trigger a PR
+$ git push -u origin fix-something
+```
