rhel4 powerlink qla2xxx HBAs not detected

Hi,

I ran through a procedure script that was generated to install my Emulex QLA-2340s on a RHEL4 box (Linux rh-linx2 2.6.9-42.0.8.ELsmp #1 SMP Tue Jan 23 13:01:26 EST 2007 i686 i686 i386 GNU/Linux). Everything seems to have gone in well, I updated the HBA firmware, installed the qla2xxx-8.01.06-1dkms rpms successfully, sansurfer is installed and appears to be working, PowerPath is installed and the licenses have "Capabilties: All" set.

But cat /proc/scsi/scsi doesn't show anything other than the onboard HDDs, and the lun-scan.sh script I downloaded from emcpower gives: "ls: /sys/bus/pci/drivers/lpfc/*/host*: No such file or directory"

I see qla2xxx & qla2300 entries in lsmod as well as a bunch of emcp* entries. The PowerPath, qlremote, and naviagent are all starting from init.d.

I don't really know what I'm missing to make the connection between all this software and the hardware on the system.

Thanks for any pointers.

Dave

do you have "/proc/scsi/lpfc" directory ?

looks you are using Qlogic and not Emulex ..you should have /proc/scsi/qlaXXX ..or something of that nature

Hi, thanks for the reply. You're right, I do have QLogic joints and I do have a /proc/scsi/qla2xxx/2 and /proc/scsi/qla2xxx/3 which have a bunch of info like:

QLogic PCI to Fibre Channel Host Adapter for QLA2340:
        Firmware version 3.03.19 IPX, Driver version 8.01.06
ISP: ISP2312, Serial# J81445

Request Queue count = 2048, Response Queue count = 512
Total number of active commands = 0
Total number of interrupts = 73
    Device queue depth = 0x10
Number of free request entries = 2046
Number of mailbox timeouts = 0
Number of ISP aborts = 0
Number of loop resyncs = 0
Number of retries for empty slots = 0
Number of reqs in pending_q= 0, retry_q= 0, done_q= 0, scsi_retry_q= 0

SCSI Device Information:
scsi-qla1-adapter-node=200000e08b8ec5f9;
scsi-qla1-adapter-port=210000e08b8ec5f9;
 
FC Port Information:
 
SCSI LUN Information:
(Id:Lun)  * - indicates lun is not registered with the OS.


I'm not sure if that last line means the Luns are not registered. Any idea how I need to register these Luns with RHEL4?

Thanks for any help.

It's an EMC Clarion CX-700 OEM'ed through Dell. Our switch has these Qlogic HBA's worldwide names registered, but the SAN's connectivity status doesn't detect them, but I'm sure that rhel's not properly configured, otherwise something like `powermt display dev=all` would give something other than `Device(s) not found.`

ok, so you have gone through these steps:

1) connected HBAs to the switch.
2) created new zones on the switch and activated the zoneset.

powerpath will not show HBAs until there are devices presented to them. So when you look in Navisphere under connectivity status you do not see the WWNs of your HBAs correct ?

Yes, Navisphere "connectivity status" fails to show the WWNs of the HBAs. But according to the instructions for installing the QLogic Drivers and PowerPath, it should detect them if everything went well with the installation of the drivers/agents/software.

Yes, to both of your questions (zoning has been done and the HBAs are connected to the FC switch) Also, I'm under the impression that regardless of whether the HBAs are connected to anything PowerPath should see and acknowledge that the HBAs are on the server on which it's installed. Am I correct?

The reason I ask is that I opened a support incident with Dell over this issue today and I was asked the same thing ---almost as if PowerPath won't see the HBAs before the zoning has been done. One of our SAN admin seems to think that it doesn't matter.

Regardless, the zoning has been done.

Thanks again.

yep ..usually it does work without problems. I have run into instances where the host was properly zoned but it still would not show up under connectivity status. So what i had to do was manually register the HBAs. On your linux box go to /proc/scsi/qlaXXX and run ls ...you will see a few hostX entries. Run cat hostX for each of them and post output here.

I'm not sure if that last line means the Luns are not
registered. Any idea how I need to register these
Luns with RHEL4?


Under "FC Port Information" you are meant to see the Clariion SP WWPNs. You aren't seeing anything so its not logging into the Clariion. You will not see luns if you aren't logged into the Clariion.

You can ignore that lun registration legend at the bottom, you aren't seeing any luns let alone luns with an asterisk next to them.

You should check your switch zoning, and if that checks out, poke the linux host somehow to retry logging into the Clariion.

Here is an example of what the driver should look like:

QLogic PCI to Fibre Channel Host Adapter for QLA2340:

Number of mailbox timeouts = 0
Number of ISP aborts = 0
Number of loop resyncs = 0
Number of retries for empty slots = 0

Jason,

Sorry if my terminology was confusing, we're not even seeing the HBA's locally on the Linux box, so logging into the Clarion's not going to happen without that, I'm afraid. The local Linux PowerPath install can't see the HBAs that are installed on that box.

Thanks for the reply.

dont worry about hba now showing up under PP ..they will once the box can see the luns. like Jason suggested can you run fdisk -l or bounce the box to see if that would force it to log in to the array. if that still does not work we can manually register host initiator. can you tell us if each hba is zoned to spA and spB ?

wrong way around :-)
Powerpath won't see HBAs / Luns if you aren't logged into the Clariion. Also it looks like the Qlogic driver is installed and has attached to the adapters fine.
