How to Find what HBA is configured on Linux?
Hi
I am working in an environment where there are many redhat physical and virtual machines, mostly Redhat 4. These servers have LUNs attached. The external storage can be EMC, NetApp or Par3.
My question is that when Storage Administrator informs that a new LUN has been presented to a particular Redhat Linux server
(1) how do I know what is the LUN ID.
(2) how do I know what kind of HBA is attached to my server.
(3) how do I scan for new LUNs.
Please guide me I have searching over the net for a while, lastly is there a guide/doc on this, the storage guide from Redhat are not in to much detail.
Thanks and regards

NAME

SYNOPSIS

DESCRIPTION
Update-rcconf-guide creates the default guide file which rcconf uses.
Update-rcconf-guide searches the package names corresponding to each service file in /etc/init.d directory from dpkg info
files(/var/lib/dpkg/info/*.list) and get the description of these packages using apt-cache. Update-rcconf-guide uses Short-Description in
priority to the description if service files has Short-Description field. Update-rcconf-guide writes those results to
/var/lib/rcconf/guide.default file.
You can write your own guide in user guide file(/var/lib/rcconf/guide) by hand. Rcconf refers Guides in /var/lib/rcconf/guide before those
in /var/lib/rcconf/guide.default.
If you install some packages after executed update-rcconf-guide, you need to re-create this file using update-rcconf-guide so as to refresh
guide.default that includes new guides for installed new services.
Notice: update-rcconf-guide was not executed when you installed rcconf
package.
