https://community.hpe.com/t5/operating-system-linux/suse-linux-8-0-not-recognizing-hp-surestore-dat24x6/m-p/2888445#M78045 I have Suse Linux 8, running on a Compaq 8500r, with a 4200 series RAID card. I have one external array connected to the 4200. <BR /><BR />I have connect an HP SureStore 24x6 to this system, when booting the device is detected as SCSI ID 5 on the built-in SCSI of the 8500(it is the only external device on the bus), but when the operating system boots, the operating system does not discover the device and add it to /dev/st* as one expects. I have /dev/st0 and /dev/st1 but neither response to a mt -f /dev/st* command, I have verified that the multi-lun kernel parameter is set, as well as SCSI tape. Are there Unix tools to scan the SCSI bus and report through the OS what is seen? <BR /><BR />I believe the tape drive itself is OK as I pulled it from backup on a Win2K system. <BR /><BR />I have also verified the switch on back for the autoloader options at 7, dip switches on bottom at switch 3 off, all others on. Changing these to autoload switch setting of 5 or dip switch 8 to off didn't change anything... <BR /><BR />Any help here greatly appreciated.

Was the external auto-loader powered on when the machine powered on?<BR /><BR />I've seen some machines ahve issues with external devices powering on after the controller has power. Just a thought. I've unfortunately not tried this series of machine before.
