As of now, NNMi DDPs clearly state in their respective 'NNMi_Driver_Readme.pdf', e.g. for 2020.07
o Uninstallation of the NNMi Device Content Pack is not supported."
Although, thankfully, this a clear statement, and in a place easily found, nevertheless,
this keeps causing major headaches while hunting for enough free disk space, appropriate backup-routines ,
and additional down-time in production to create a file system backup before installing a DDP.
Please also note:
This need for tackling additional steps involving additional folks to get them done,
is not exactly a recommendation for installing DDPs in a timely manner
Hence below QUESTIONs about DDP installation in RHEL:
> Would something like a NNMi backup/restore (nnmbackup.ovpl/nnmrestore.ovpl)
plus a OS' rpm -e <package name>' work for (preparing for) un-installing a DDP ?
...and if so,
> could you please test and support proper steps to allow for smoother DDP installations, please?
