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
#LTO4
manufacturer="HP" model = "Ultrium 4-SCSI"{
scsi2logical=1
can-bsr=1
auto-lock=1
two-fms=0
drive-buffering=1
buffer-writes
read-ahead=1
async-writes=1
can-partitions=0
fast-mteom=0
# If your stinit supports the timeouts:
timeout=180 # 3 minutes
long-timeout=14400 # 4 hours
#
mode1 blocksize=0 compression=0 density=0x00 # 800 GB, Creates a device file with compression disabled.
mode2 blocksize=0 compression=1 density=0x46 # 1600 GB, The density code for data compression enabled by default.
mode3 disabled=1
mode4 disabled=1
}
stinit -f /etc/stinit.def
mt -f /dev/st0 status
mt -f /dev/st0l status
Reboot and good to go. To check the Tape Drive status:
sg_logs -a /dev/st0
