HP StorageWorks under Redhat Linux

Hi,
I have attached a new HP StorageWorks library
housing 3 tapes on a Proliant D360 server running Rehat Linux AS3. After reboot I do not see any tape even scsi when executing "dmesg" or "lsmod". I have agot a script to scan the scsi but I could not use it (many error). I know that the drivers are included in AS3, I also know that if I re-installed the system I'll see the adapter and tapes but the system is used. How can I do to avoid Linux re-installation ? Thanks

Re: HP StorageWorks under Redhat Linux

Did you verified that the /etc/modules.conf or /etc/modprobe.conf files are listing the module for the scsi adapter?

Can you manually load the module using modprobe.

Try running kudzu, also disable kudzu at startup.

Deja vu.

Cheers.

Re: HP StorageWorks under Redhat Linux

Thanks Ivan,
I have checked an equivalent system and noticed that the /etc/modules.conf of that system has an additional line "alias scsi_hostadapter mptbase".
Do I need to add that line to my system and
execute the command "modprobe scsi_hostadapter" ?
There is no "/etc/modprobe.conf" file on my system, may I create it with the content of that other system ?
Thanks

Re: HP StorageWorks under Redhat Linux

I do have the same problem on RedHat. The thing is that I can see the exchanger but I can't see the drive.
Here is the hp_rescan output:
[root@atenea /]# hp_rescan -a
Rescanning /proc/scsi/qla2xxx/0...
Removing /proc/scsi/qla2xxx/0, target 2, LUN 32
Scanning /proc/scsi/qla2xxx/0, target 2, LUN 32


scsi0 00 00 01 HP HSV100 3028 Direct-Access
scsi0 00 01 00 HP HSV100 3028 RAID
scsi0 00 01 01 HP HSV100 3028 Direct-Access

scsi0 00 02 03 HP NS 567a RAID
scsi0 00 00 00 HP HSV100 3028 RAID

And this is my /etc/modules.conf:
[root@atenea /]# cat /etc/modprobe.conf
alias eth0 tg3
alias eth1 tg3
alias scsi_hostadapter cciss
alias scsi_hostadapter1 qla2300

alias usb-controller1 uhci-hcd
alias scsi_hostadapter2 lpfc
options lpfc lpfc_nodev_tmo=30 lpfc_lun_queue_depth=8 lpfc_discovery_threads=1


How did you resolve it?

Re: HP StorageWorks under Redhat Linux

Hello Consty,

A few questions about your configuration.
1) Are you using a Proliant DL360 G3 or G4?
2) Are you connecting to the onboard/embedded SCSI controller or using a separate adapter plugged into a PCI slot?
3) If you're using the embedded SCSI controller are you using the latest drivers available at http://h18007.www1.hp.com/support/files/storage/us/download/23089.html?
4) If you're using a separate SCSI adapter plugged into a PCI slot do you know the make, model number, chipsets, SCSI level (i.e. Ultra2, Ultra160, Ultra320) of the adapter?
5) Did you previous have any SCSI devices (especially tape) attached to the system?
6) What is your output for a 'lsmod' command?

Re: HP StorageWorks under Redhat Linux

Sorry for the delay, I was sent to another mission.
Well, to go fast I solved the problem by re-installing Linux. But I would have prefered to see the drives (st0, ....) without re-installing the whole O.S.
Thanks a lot for help and will be grateful if I could get the way of solving the problem without re-installing Linux.
Regards
