RE: Help regarding PCI Express hot Plug functionality in kernel 2 .6.8

[Bhupesh Kumar Pandey, Noida]

Hi thanks a lot for a reply.
Actually I want to use hot plug feature of PCI Express for FC-HBA. I have
investigated for 2.4 kernels, but they do not support hot plug here.
I don't have any idea about 2.6 series.
I believe that in Kernel 2.6 the driver in the below mentioned is the same
as the driver I am referring to.
/usr/src/linux/drivers/pci/hotplug/pciehp
So I want to know the functionality of hot plug support on PCI Express in
Kernel 2.6.8. How the information flow and what are the limitations.
Please help me out and thanks in advance for your concern.

What is not working for you?

Also, please read REPORTING-BUGS in the kernel source tree for how to
report an issue properly.

Why not try the driver out in 2.6.10 (as that's the most recent kernel)
and report any problems that you might have with it?  That would
probably be easier.

Great question, care to ask this on the linux-kernel mailing list and CC me?
That way I can answer it in public to enable everyone else to know the
answer, and let the search engines pick it up.

Also, please research this yourself, the information is out there about this
very topic.

good luck,

Yes it supports it.  It should work just fine.  If not, please let us
know any problems you have.

Actually there are three thing, which I want to verify
	1. It has support for Hotplug of FC-HBA on PCI Express
	2. DISK(mainly iSCSI) addition to FC-SAN 
	3. PnP of Disk(mainly iSCSI) recognition by iSCSI Target(Including
FC side and iSCSI side)
And what is the information flow, how it works and what document and driver
code I should study.
