Starting from OneFS 8.2.1, the patch installation process has been simplified and enhanced. Prior to OneFS 8.2.1, you will see the following behaviors when you apply a new RUP on top of an existing one:
In OneFS 8.2.1, the simplified patch installation process includes the following:
Note: This process cannot apply to firmware or OneFS upgrades.
The following is an example to explain how this feature works:
In this example, the test patch, patch-1234, has been installed as shown below:
# isi upgrade patches list
Patch Name Description Status
---------------------------------------------------
patch-1234 base patch to be deprecated. Installed
---------------------------------------------------
Install a new patch, test-deprecated-patch, which is to deprecate the previous one patch-1234. To do this, leverage the command isi upgrade patches install as shown in the following:
# isi upgrade patches install /ifs/test-deprecated-patch.pkg
The below patches are deprecated by this patch and will be removed automatically:
- patch-1234
Would you like to proceed? (yes/[no]): yes
Requested install of patch test-deprecated-patch.
In this case, it will automatically detect an existing deprecated patch installed in the cluster and ask you if you want to proceed to remove it.
During the installation, the status of patch-1234 is AdHoc as shown below.
# isi upgrade patch list
Patch Name Description Status
--------------------------------------------------------
patch-1234 base patch to be deprecated. AdHoc
test-deprecated-patch patch with deprecated tag Installing
--------------------------------------------------------
Total: 2
AdHoc status means:
After the new patch has been installed and the deprecated patch has been removed, the patch status will change to the following:
# isi upgrade patch list
Patch Name Description Status
--------------------------------------------------------
test-deprecated-patch patch with deprecated tag Installed
--------------------------------------------------------
This feature can dramatically simplify the upgrade process by removing unnecessary steps, node reboots, and service restart. As a result, it makes the patch upgrade process more efficient and secure. Based on this, Dell Technologies recommends you to leverage this feature when it applies.
