Could someone please advise the best method to discover if a hba has been installed. I have issued a rpm -qa with for the driver but not present what I require to find out is if the hba is present.....

For example HPUX i can run a ioscan.

Regards,
Pat

Hi,
rpm -qa is used to see all installed packages.

I hba is a package name then run:
rpm -qa |grep hba

If you don't see it - it's not installed (at least not as RPM package).

Normally, you can find messages about the dicovering of the hardware in "dmesg" output.

Also, you can consult some details via the /proc/scsi/qla*/[0-9] special files (For QLOGIC HBAs".

lspci will show you the PCI devices in the system.

Hi Pat,

lsmod will list all the modules (drivers not built into the kernel) that are loaded up.

Might help us if you explain what HBA is...

"lspci" will list all adapters on the computer's PCI bus, whether they have drivers installed or not. To get more information, add option '-v' or '-vv'.

Andrew: HBA means Host Bus Adapter - most often this acronym refers to a FibreChannel card, but technically it could mean any adapter that connects the computer's expansion bus to another type of bus.

2 other ways are:

1) looking in /proc/scsi/scsi for the appropriate device instances, and

2) physical inspection of the box for a device with fiber connectors on it.
