[clue-tech] how to disconnect iSCSI drive?

[Jim Ockers]

Hi CLUEbies,

I set up the iSCSI enterprise target (iet) on a CentOS 5 box with 
2.6.18.blah kernel.  It was as simple as "make ; make install" from 
their tarball.  I made a big empty file and configured iet to use that 
as a target disk with fileio access.

Target iqn.jockers-lnx1.domain.com:storage.disk.example.1
        Lun 0 Path=/bigfile.bin,Type=fileio,ScsiId=IET-Example,ScsiSN=JIMO

Then I downloaded the Microsoft iSCSI initiator 2.08 and connected to 
it.  All I needed to know was the IP address/hostname of my CentOS box.  
Easy peasy lemon squeezy.  Except for there seems to be no way to 
disconnect it once connected.  Do any of you know how to do this?  
Incredibly even google searches for how to disconnect an iSCSI drive 
from the Windows initiator come up with nothing useful.

Am I the only person in the world who's ever wanted to disconnect an 
iSCSI drive so I can change its configuration?  Say, make the disk 
bigger, or rewrite it with nulls, or something.  Does anyone out there 
know how to disconnect the drive without rebooting my windows box?  I'm 
sure a reboot will make it go away but since it is just a software 
device driver it seems there should be an easier way than that...  
Stopping the windows service "microsoft iscsi initiator" does not make 
the disk go away either.

By the way there is no "unmount" "eject" "disconnect" or other useful 
right-click options.  By all appearances it is a locally connected 
physical disk with no way to get rid of it except a reboot.  Argh.  I'm 
kind of afraid I will crash my windows box if I run the command 
"/etc/init.d/iscsi-target stop" on the CentOS box.

Thanks,
Jim
