can not restore or copy large database/files from the storage device. dmesg is spitting out scsi layer device reset errors.

We cannot restore database, or even copy large files. The filesystems on storage keeps locking up after a short while of heavy activity. Everytime I start a restore or copy of the backup files, it will work for a while then hang doing nothing and I have to kill the login shell of the user running the command (kill of restore or copy process hangs that shell) to get the filesystem back.
I think the storage or drivers for storage are not quite hooked up properly there.
