Please hold off on upgrading your RedHat systems (possibly centos too).
I just found out the hard way that kernel 3.10.0-1160.36.2.el7.x86_64 is
not compatible with DB2, and after the node reboot DB2 would not work
anymore, not only on TSM, but neither on HPSS. I had to revert the
kernel to 3.10.0-1062.18.1.el7.x86_64 to get DB2 working properly again.
For the record I have been running Spectrum Protect Extended Edition
8.1.12 on 3.10.0-1160.31.1 (genuine RHEL 7.9) since the 11th of June
this year.
I would say therefore there is no need to roll back quite so far as
3.10.0-1062.18.1 which is quite ancient now.
Can't test anything newer as I am literally in the middle of migrating
our TSM server to new hardware and a RHEL 8.4 install. Spent yesterday
in the data centre re-cabling the disk arrays to the new server; neat,
tidy and labelled this time :-)
