installing qlogic 2312 on Redhat linux 3

[tom quach_1]

Dear all,

Please show me the process of how to install the driver for this hba card qla2312.
Here is what i've done.
installed the card to RedHat linux 3, rebooted the server,using the hardware browser and see my qla2312 Fibre Channel Adapter in the system.
From here, where can i start. How can i see the WWN, what tool should i use.
-is there an equivalent command like HPUX (ioscan) to see new device in Redhat linux?
Do i need to download any driver?
Where can i download Qlogic FO driver for mulipathing.

Thank you,
Tom

Try qlogic.com for the driver. The installation is pretty straight forward:

.1 Download driver from qlogic
.2 Read the README file
.3 Compile module and insert into running kernel
.4 Set-up the system to auto-load the kernel at next boot either using an initrd or modprobe.conf (all of this is in the README file)

Hope this helps.

Hello,

I forgot to mention that i connect this HBA to an Hp EVA 3000.
Should i download the driver from HP site?
Any command in Linux to see the new LUN or hard drive from command line?
Regards,
Tom

Hi Tom,

I dont quite know if there is a command that will show all that info but you could look at the output of dmesg and see what it says about your devices.

I last installed a qlogic hba 2300 and in the driver tarball that I downloaded there were a couple of utilities that showed the luns, etc.

You could also look in the /proc directory and get more info about your hardware.

I would look for a driver from HP first and then if that doesnt work head over to qlogic.com and try one of their drivers.

Hi Marius,

In RedHat linux,
How to verify that the device is installed correctly.

Hi Tom,

Unfortunately I do not remember/know if there is a command to show the information you need. "lspci" will show you the pci devices attached.

You can try the command "dmesg" and look through the output for the information that interests you (dmesg | grep qla).

Also in order to do multipathing you need the driver from qlogic or some other manufacturer. RHEL3's qlaxxxx driver does not have multipathig capabilities.

Good luck!

Thanks-Marius,

IMHO, you can install drivers from HP site http://h18004.www1.hp.com/support/files/server/us/locate/101_5561.html#32

lspci, "cat /proc/ioports", "cat /proc/partitions" will show you the qlogic card if you have installed your kernel driver.

For your disk configuration, you need to configure that from SAN box before you connect to your server.

Thank you for the reply,


after presenting a disk to RedHat Linux from HP EVA3000
and now it can see the devices.
[root@gridlx hp_fibreutils]# ./lssg
sg0 0,0,0,0 HP HSV100 3025
sg1 0,0,1,0 HP HSV100 3025

How do i create a volume group from here?

Regards,
Tom

[Sung Oh]

You can start with initializing disks using "pvcreate" command and use "vgcreate" to create volume group.

here is step by step instruction and some examples from Redhat website.

> sg0 0,0,0,0 HP HSV100 3025

Tom,

LUN 0 / sg(number) is the array controller device, it does not provide storage capacity. You better check with:

# lssd

[tom quach_1]

Hello Uwe,


[root@gridlx hp_fibreutils]# ./lssg
sg0 0,0,0,0 HP HSV100 3025
sg1 0,0,1,0 HP HSV100 3025

#lssd (it returned nothing)

What am i missing?

Regards,
Tom

Hello Tom,
that looks like no Virtual Disk is presented to the server.

The storage manager for the EVA must create a Host entry, which includes the Fibre Channel adapter's WWN and the correct OS Type (don't have the list handy, but I guess it's "Linux"). Then he needs to create a Virtual Disk with the desired size and VRAID level. Finally he needs to map the Virtual Disk into the LUN address space of the Host entry - that's called presentation.

[tom quach_1]

Hello Uwe,

I did all of that.
Create a host on EVA3000, create 2 LUNs of 2Gb and presented to the Linux host.
On My HP-UX i do not have any problem, but RedHAt linux is new, so somehow i get all kind of trouble.

If thing goes right with
lssd i should see the LUNs?

Regards,
Tom

[Uwe Zessin]

Yes, definitely - here is an example from an older installation (SLES 8, though):
# lssd
sda 0,0,0,0 LSILOGIC 1030 IM 1000
sdb 2,0,0,1 HP HSV100 3025 5000-1fe1-5005-abcd


I would double check:
- click the [presentation] tab within CV-EVA on the Virtual Disk or Host entry
- go into the adapter BIOS and check 'Scan Fibre Devices'

Hello,

to configure Qlogic Crad
boot hosts
enter setup Ctrl-S
enter menu F10
enter PCI menu
activate Qlogic cards IRQ5

boot to linux

verify you have qla2300 in /proc/scsi

check in /etc/sysconfig/hwconf

class: SCSI
bus: PCI
detached: 0
driver: qla2300
desc: "QLogic Corp.|QLA2312 Fibre Channel Adapter"
vendorId: 1077
deviceId: 2312
subVendorId: 0e11
subDeviceId: 0104
pciType: 1
pcibus: 4
pcidev: 3
pcifn: 1


if not run:

kudzu

configure two times (once per card)

you will see controler as sg1,sg2 ... (sg is Scsi Generic)
disk appear as sda,sdb, ...

Hope This help.

Thank you for the reply

[root@gridlx hp_fibreutils]# ./adapter_info
/proc/scsi/qla2300/0: STATE=READY WWNN=200000e08b0b2321 WWPN=210000e08b0b2321

rescan the HBA
[root@gridlx hp_fibreutils]# ./hp_rescan -l
QLogic adapters: /proc/scsi/qla2300/0
Emulex adapters:


[root@gridlx hp_fibreutils]# ./hp_rescan -a
Sending rescan signal to /proc/scsi/qla2300/0...
Scanning /proc/scsi/qla2300/0, target 1, LUN 32

scsi0 00 00 00 HP HSV100 3025
scsi0 00 01 00 HP HSV100 3025

when do a
#lssd (nothing returned, what happens)
