Scsi bus scan
Hi,

I have presented a LUN to a VM (RHEL 5.8) and need to scan the scsi bus in order for the OS to pick it up.

On FC attached hosts I can:

Code:
echo "1" > /sys/class/fc_host/host0/issue_lip
echo "- - -" > /sys/class/scsi_host/host0/scan



....but this does not work on my vm.

Anyone know how to get the OS pick up the new disk space without having to reboot the box?

R,
D.

discover.conf(5)						File Formats Manual						  discover.conf(5)

NAME

       discover.conf -- configuration file format for discover(1)

Description
       Discover  looks	for  configuration  files  in a configuration directory, containing a number of files.	These define the system buses that
       should be scanned by default, those that should never be scanned, and the URLs for hardware data files beyond the local copy provided  with
       the software.

       The file format is XML; the DTD	   is provided with the Discover software, and can be used for informational or validation purposes.

Examples
       Establishing default buses to scan

       <?xml version="1.0"?>

       <!DOCTYPE conffile SYSTEM "conffile.dtd">

       <conffile>
       <busscan scan="default">
       <bus name="ata"/>
       <bus name="pci"/>
       <bus name="pcmcia"/>
       <bus name="scsi"/>
       <bus name="usb"/>
       </busscan>
       </conffile>

       A more complex example

       <?xml version="1.0"?>

       <!DOCTYPE conffile SYSTEM "conffile.dtd">

       <conffile>
       <busscan scan="default">
       <bus name="ata"/>
       <bus name="pci"/>
       <bus name="pcmcia"/>
       <bus name="usb"/>
       </busscan>
       <!-- My ancient SCSI card locks up when probed -->
       <busscan scan="never">
       <bus name="scsi"/>
       </busscan>
       <data-sources>
       <data-source url="http://www.example.com/discover/xfree86.xml"
       label="Updated XFree86 hardware information">
       </data-sources>
       </conffile>

Authors
       Josh Bressers, John R. Daily, and G. Branden Robinson developed the current implementation of Discover for Progeny Linux Systems.

       The Linux implementation of the system-dependent interfaces is derived from detect, by MandrakeSoft SA.
