Hi,

My environment is HP DL380p Gen8 Server install two PCI-E SAS HBA card below and two IBM TS2250 tape drives:
HP H222 => Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS2208 PCI-Express Fusion-MPT SAS-2 (rev 05)
IBM 6Gbps SAS HBA => Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 03)

I connect each of TS2250 to SAS2208 and SAS2008.

I can seen the TS2250 in BIOS post screen.

But when I boot into SLES 11 SP1, I can not see any tape device in /dev folder,

Also I use lsscsi command, the out put will not show my tape device (IBM TS2250), But I can use lspci to find SAS2208 and SAS2008


and there has a strange part!
some time.. (may be after I reboot the SLES), I issue lsscsi command, Tape driver will show in the output !!
But once I reboot again it will gone.



I have trying to do below already:
1. update SAS2208 (HP H222) firmware and BIOS (now firmwarei is 13.10.141.00, bios is 07.25.05.00)
2. update mpt2sas driver ( from 11.00.01.00 to 13.10.02.00 )


Does any have the same problem? or any one can help to fix/identify this problem?


P.S
I have try SLES 11 SP2 too, all tape drives will show in /dev/ folder and lsscsi command output every reboot!
But unfortunately we have some application must need install on SLES SP1...

Hi nnnnnnine,

so it seems to be either some driver or configuration problem. Do you by chance have the related output from syslog and/or dmesg? Have you ever issued a manual SCSI rescan, it might give further hints?

Are you under support contract so you might get some info on what change (between SP1 and SP2) may have caused this, and probably some specific help offering?
