DL380 G4 + SLES9 + StoragwWorks Ultrium 215

Please, help.

BIOS recognize my tape device fine:
Port1 SCSI ID 3

But in Linux I cannot see anything about it.
dmesg and hp_ltt 4.2.1 are found nothing.

P.S. SLES9-SP3 for EMT/AMD 64.

There's many ways to approach this. If dmesg doesn't show the device, that's a big strike against it working. Does dmesg at least show the SCSI card? If not, you'll need to load in the kernel driver module for that card. What model card is it? The built-in one? If the card shows up fine in dmesg, then try issuing some 'mt' commands. Load a tape in the drive, let it initialize, and try the various /dev/sd devices. If it's on ID 3, then /dev/sda3, /dev/sdb3, /dev/sdc3, might be good places to start. 'mt -f /dev/sda3 status' should give a 0 return code. Most likely, none of the /dev/sda-c devices will work as those are normally for disk drives and their associated partitions. Also try some of the standard default tape devices... /dev/st0 or /dev/mt0.

`mt -f /dev/st0 status` says "mt: /dev/st0: No such device or address". I began with this command. /dev/sda3 and others not work too.

SCSI card detected perfectly - all my HDD are SCSI:

SCSI subsystem initialized
HP CISS Driver (v 2.6.8)
cciss: Device 0x46 has been found at bus 4 dev 3 func 0

`lspci` found SCSI controller too:

0000:04:03.0 RAID bus controller: Compaq Computer Corporation Smart Array 64xx (rev 01)

In general, it's not a good idea to hang a tape drive off a RAID controller. Is this even supported for your server/drive combo?

[VBalabhai]

I have the only SCSI controller.

[skt_skt]

try "dmidecode" and redirect the output to a file.. Try to confirm if all the disk and tape devices are listed there..

[VBalabhai]

`dmidecode` does not show SCSI devices at all.

[skt_skt]

cat /proc/scsi/scsi

Do u have lshw rpm installed.

# rpm -qa|grep -i lshw
lshw-2.05.01-1.0.el2.rf

# lshw >lshw.out
