Hi All,

I have 2 HBA's in my system, in that one shows as READY state and the other HBA shows as DEAD state. I have asked the datacenter guys to to connect the HBA to another switch port and I rebooted the server. After reboot the second HBA came to READY state but after some time again it went to DEAD state.

[root@localhost /]# lspci | grep -i fibre
0b:00.0 Fibre Channel: QLogic Corp. ISP2432-based 4Gb Fibre Channel to PCI Express HBA (rev 02)
0b:00.1 Fibre Channel: QLogic Corp. ISP2432-based 4Gb Fibre Channel to PCI Express HBA (rev 02)


cat /proc/scsi/qla2xxx/1

Host adapter:loop state = <DEAD>, flags = 0x45a03

Is this the problem with the server or with the storage end, Any help!!!!!!!!

Not alot we can help WITH....you don't give any details, and there are too many variables to guess at. What kind of SAN? Switch? Did you check the cables and qbics? Try different fibers? Version/distro of Linux? Multipathing or not?? What????

You don't have to reboot the server when you move cables, either. Best thing I could suggest to you is to contact your SAN folks, and get them to look at different parts of the system (cables, switch, etc.), to make sure they're ok. Then get with your SAN vendor, to make sure you're setting the driver/software up right.

Thanks for the info, BTW its a Direct Class switch, Redhat Linux and we are using Multipathing. I have asked the DC guy to check the switch port they said the switch port is good, and they suspect the card may be faulty. When i check the logs it shows the below error messages. My doubt is whether this a problem with HBA card or with SAN side. If HBA card is faulty how to confirm it, because i couldn't see any error in logs.

Nov 30 21:35:32 kernel: qla2400 0000:0b:00.1: LOOP DOWN detected (4 4 0).
Dec 1 21:09:20 network: Bringing up loopback interface: succeeded
Dec 2 11:28:34 kernel: qla2400 0000:0b:00.1: LOOP DOWN detected (4 4 0).

Well, the fact that the card starts, then goes dead is a pretty good indication. However, as I mentioned before, you should also verify the fiber connection. Maybe move the working cable to the 'dead' card, and vice-versa, and see if the problem follows the cable, or remains with the card.

Hi,

San team confirms that there is no problem from their end and DC guy has checked the HBA cable connected to the switch port and it is good as well, also he said the hba leds has 3 flashing orange lights. It means the problem with the card?

SAN front end tool will always work the the client installed in the server. You can confirm the error from your side. Go to "/opt/QLogicxxxx/SANsuffer/xxx" there is some set of commands where you can test the device is dead or alive. Also check for the manual page and rescan the device. You would get some detailed output for your verification. There you can find and confirmed the error is with OS or with SAN device.

Also check for the "/proc/scsi/qlaxxx/" host values.

Best Regards

If you're asking a question, we've got no idea...that's YOUR card, check the manual that came with it, and see what 3 flashing orange LED's means. If the working card DOESN'T have them, again, signs point to a card fault.
