HOW TO FIND HBA DETAILS IN LINUX

[Kennedy G. Doss]

LINUX SAs:

How do I find the make/model of all my HBAs on my Linux Server? I am looking for something similar to "ioscan -fnC" in HP-UX.

At the moment, I use "dmesg | grep -i Fibre" to collect information. I dont always get the results if the message files have outgrown their size values.

Any input would be most appreciated.

Regards,
Kennedy

You probably will find your HBA module in /etc/modprobe.conf. There you can identify with "modinfo" if the module is for QLOGIC or EMULEX. Then use SanSurfer (qlogic) or HBA Anywhere (emulex) to obtain detailed and accurate information.

I typically use 'lspci' to identify all peripherals, you could do:

lspci |grep -i -e fib -e hba

Hi Kennedy,

depending on kernel version you also can find some information under /sys.

search
/sys/class/scsi_host/host?/*
or
/sys/class/fc_host/host?/*

here you can find information about WWN, topology, speed, etc

dmesg gives info as well, you can find the logfile since boot in /var/log/dmesg.

Hi..

You can find HBA details by
#df -h

I see above someone mentions lspci, you can add lspci -v, lspci -vv, and lspci -vvv for more verbosity.

Locating the WWPN for a Linux host

This topic describes several methods you can use to locate the worldwide port name (WWPN) for an Intel® or AMD host that is running the Linux® operating system.
About this task

* Locating the WWPN without restarting the host

To locate the WWPN without restarting the host, you can use any of the following methods:
o For QLogic or Emulex adapters, you can find the WWPN in the /proc/scsi/adapter_type/n directory, where adapter_type is the host adapter type and n is the host adapter number for your card. Your host adapter type can be either qlaxxxx for QLogic adapters or lpfc for Emulex adapters.
o If you downloaded a QLogic adapter from the QLogic Web site instead of using the default version that is shipped with RHEL, to find the WWPN run the cat /proc/scsi/adapter_type/n command, where adapter_type is the host adapter type (for example, qla2xxx or qla2300), and n is the host adapter number for your card.
o For a QLogic adapter that is shipped with RHEL 4.x or earlier, to find the WWPN run the cat /proc/scsi/adapter_type/n command, where adapter_type is the host adapter type, and n is the host adapter number for your card. In most cases, the adapter type is qla2xxx.
o For a QLogic adapter that is shipped with RHEL 5.x or later, the adapter WWPN information might not be available in the/proc/scsi/adapter_type/n directory because of the migration to sysfs, If this is the case, run the following command:

cat /sys/class/scsi_host/hostn/device/fchost\:hostn/port_name

where n is the host adapter number for your card.

[John McNulty_2]

Actually, /sys/class/scsi_host/host0/device/fchost\:host0 (for example) is a symbolic link that points back to:

/sys/class/fc_host/host0

So you might as well just go there (less typing) and cat the contents of port_name, etc.
