After applying the InfoScale patch, the LLT kernel module appears to be incorrectly linked to /dev/null.

Problem

After applying the 8.0.2.3100 patch, the LLT kernel module appears to be incorrectly linked to /dev/null

Error Message

ls -al /opt/VRTSllt/modules/llt.ko.5.14.0-570.12.1.el9_6.x86_64*
lrwxrwxrwx. 1 root root        9 Jun  5 22:46 /opt/VRTSllt/modules/llt.ko.5.14.0-570.12.1.el9_6.x86_64 -> /dev/null

Cause

This is an expected behavior seen immediately after the patch installation. During the patch installation process, temporary symbolic links to /dev/null may be created to avoid module loading conflicts. This state does not impact product functionality.

Solution

Once the LLT services are started, the correct module linkage is restored automatically.

Example:

lrwxrwxrwx. 1 root root       64 Jul  6 20:08 /opt/VRTSllt/modules/llt.ko.5.14.0-570.12.1.el9_6.x86_64 -> /opt/VRTSllt/modules/llt.ko.5.14.0-570.12.1.el9_6.x86_64-nonrdma
