Redhat 8.3 configure LTO4 Tape Drive with SuperMacro SAS adapter

My Supermacro SAS adapter/Marvell 88SE9485 SAS controller support has been removed from Redhat 7/8. Check for the model:

# lspci -nn

01:00.0 RAID bus controller [0104]: Marvell Technology Group Ltd. 88SE9485 SAS/SATA 6Gb/s controller [1b4b:9485] (rev c3)

Install mvsas from https://elrepo.org/linux/dud/el8/x86_64/

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
yum install https://www.elrepo.org/elrepo-release-8.el8.elrepo.noarch.rpm
yum install kmod-mvsas

Set /etc/stinit.def

}

stinit -f /etc/stinit.def
mt -f /dev/st0 status

Reboot and good to go. To check the Tape Drive status:

sg_logs -a /dev/st0
