Hp Dl380 G4 Smartarray 6i, Dat72

Bruno_48 — Fri, 03 Jun 2005 06:34:50 GMT

I'am installing a HP DL380 in RAID 1 with Dat72 linkek into a backplane in smartarray 6i with a duplex configuration and i had installed linux 2.1 enterprise Advanced Server when i'am trying to acess to /dev/st0 he can't find such scsi dive attached, i tryed to install the latest hp support paq for linux 2.1 E. AS but didn't works i have edited /etc/rc.local

for x in /proc/driver/cciss/cciss[0-9]*
do
echo "engage scsi" > $x
done

but that doesn't work's to.

So you've got the hot-plug drive, plugged into the front with the other disks, yes?

When the system booted up, did you see the tape drive listed when the Array controller BIOS went through post?

Also, take a look at both '/proc/scsi/scsi' and '/var/log/dmesg' to see if there's any mention of a tape there.

What kernel are you running on the AS2.1 kernel now? The latest eratta, or the one that came with the distribution?

have you kept the tape drive powered on when you rebooted the system. (first have you rebooted the system)

also check dmesg output and check is there any entry for st0 or nst0

I may not be understanding this correctly.. but
are you having a problem with the 6i controller? If so, then you may want to make sure the driver has support.. from what I can remember the cciss.o kernel module in AS 2.1 does not have support for it. You can verify this by doing

user@host $ strings /lib/modules/2.6.10-1.770_FC3/kernel/drivers/block/cciss.ko | grep 6i

If you see "Smart Array 6i" then it has support, otherwise you are out of luck and will have to install a driver for it (or update the kernel to a version that does support the 6i controller)

If the 6i controller is not the case, then I have nothing more to offer. :)

i have ran strings: /lib/modules/2.6.10-1.770_FC3/kernel/drivers/block/cciss.ko: No such fi

and theres the result

what the person gave was just an example. you should modify it to suite your need.

to suite your need, try this method:

strings /lib/modules/`uname -r`/kernel/drivers/block/cciss.o |less

it will present you with char messages found in that file, in that look for 'Smart Array 6i' if found then it means your system supports that controller otherwise you may have to upgrade your kernel which supports it.

which update of RH 2.1 you are running?

[root@xpty root] strings /lib/modules/2.4.9-e.3enterprise/kernel/drivers/block/cciss.o |grep 6i
theres the result

it looks like your kernel supports the 6i driver. so you should not be having any problem in accessing it.

but strange that you are saying dmesg output does not show up any st0 information.

try running kudzu and see whether it can find the hardware.

kudzu do nothing.
theres a part of dmesg:
cciss0: No device changes detected.

is your tape drive model no is C7438A? if it is so, then kernel is able to detect the system.

in that case try loading st module by 'modprobe st'

and after that put dmesg and see whether you are getting some st message at the bottom.

Bruno_48 — Fri, 03 Jun 2005 11:44:25 GMT

in dmesg theres no mention to st

[root@xpty root]# mprobe st

[root@xpty root]# lsmod

st 30548 0 (unused)

can you attach your dmesg output and /var/log/messages. if not me somebody else can enlight on what is going wrong.

Re: Hp Dl380 G4 Smartarray 6i, Dat72

Bruno_48 — Fri, 03 Jun 2005 12:01:01 GMT

Here is the attachment with the dmesg and /var/log/messages output

Hi Bruno,

look for some device called cciss0.
find /dev -name cciss0 will help you.

I guess that this is the device for your tape. From your messages file we have

Jun 4 00:21:51 lx0srp1 kernel: scsi0 : cciss0
Jun 4 00:21:51 lx0srp1 kernel: Vendor: HP Model: C7438A Rev: V312
Jun 4 00:21:51 lx0srp1 kernel: Type: Sequential-Access ANSI SCSI revision: 03
Jun 4 00:21:51 lx0srp1 rc: Starting compaq_cciss_scsi: succeeded

Hi Bruno,

I found a document that may help you better. It is about Smart Array version 5 but I think that the same applys to version 6.

That's the document

Well those logs are showing the tape drive as being listed (the fact that a 'Sequential-Access' device is listed in '/proc/scsi/scsi').

It certainly does seem odd that the drive isn't being tied when the ST module is probed.

Are there any references to 'TAPE' in '/etc/sysconfig/hwconf' ?

Stuart Browne — Mon, 06 Jun 2005 04:05:59 GMT

Well, there's a Sequential access device listed in '/proc/scsi/scsi', and if the 'st' module is loaded, '/dev/st0' (or nst0) should be able to access your tape drive.

xyko_1 — Mon, 06 Jun 2005 06:54:36 GMT

Hi Bruno,

did you look at the documentation I told you on may last response ? It says that your kernel has to be configured to accept tapes attached to smartarray cards. I think it's not a default configuration so tou have to pay attention to it.
