Hi Stan, Congratulations on getting it working! I had no problems the first 
time around. I'm wondering if it has something to do with doing a "yum -y 
upgrade". I also tried the latest version of ietd and the next to latest just 
to see if that was it. It compiles just fine.
You were able to use the latest 4.16?

Brad

Subject: Re: Help with CENTOS iscsi / vmware esx-i

Brad,

Thanks for prompting me to do this!  I just completed bringing up a LUN from my 
Ubuntu 8.04 LTS Server machine and its currently mounted on my ESXi server.  I 
cheated a little; as I don't have LVM or any extra partition space available -- 
I just made a simple loopback file.

On Linux:
Installed iscsitarget ... (for anyone doing this.. there is a bug with 
iscsi-target-source and Ubuntu ..  I followed a bug response to actually 
compile the module:
https://bugs.launchpad.net/ubuntu/+source/iscsitarget/+bug/208281/comments/2 )
dd if=/dev/zero of=/media/hd-image1 count=2000MB
mkfs.ext3 -c /media/hd-image1  << Probably not needed.. but I wanted to mount 
it locally first.

[EMAIL PROTECTED]:/etc# cat ietd.conf  | grep -v "#"

Target iqn.2008-10.corp.claramartin:cmcdata1.local.images.hd-image1
        Lun 0 Path=/media/hd-image1

Started iscsi-target....

At this point, I am running Windows 2008 on my laptop -- I connected with the 
Windows 2008 iscsi initiator.  The partition showed up as uninitialized in 
Computer Management, so I initialized it, and formatted it.  I cancelled the 
format about 2% through, and assumed everything was going to work (I saw a 2GB 
disk available).

I went to ESXi, Config tab, Storage Adapters tab:

- Enabled iScsi
- Added dynamic host by IP
"vmhba37:1:0" shows up as a disk of 2.25 GB (lun id 0)

Clicked storage, clicked add storage, and added the disk (2.00 GB, 1.72GB 
available after format, its now VMFS3).

I haven't actually booted a VMWare instance off the system yet, but so far it 
looks reasonably good.  I am still wondering why I just iscsi'd a 2GB file off 
from a raid 5 set of 7200RPM ide drives from a dual quad zeon with onboard 
15krpm drives and a 2GB raid card.. but thats another story.

Hi everyone, I'm a long time lurker to the list and would like to see if anyone 
has ever come across an issue I'm having now.



I've created an iscsi SAN on a server running CENTOS 5.2 (Redhat based) and the 
iscsi-target package (ietd) which is promoted as a free, enterprise ready 
iscsi-target. On the other end VMWARE-ESX-i 3.5 with iscsi support.



When I first put this together, it worked just fine. I went and tried OpenFiler 
for the iscsi SAN, but decided to go back to CENTOS.



The problem is now that when I get VMWARE to attach to the iscsi-target it 
gives me an error that it can't create the file system. (Error SCSI: 4506: 
Cannot find a path to device vmhba32:0:0 in a good state. Trying path 
vmhba32:0:0).



The target shows up and VMWARE even tried to write a partition (Which I've 
deleted in between tries), but fails while trying to format the disk. I can see 
the new partition on the drive.



I've checked the configuration on both ends at least 20 times, googled for 
answers, and even recompiled the ietd software and just can't seem to figure it 
out. The ietd.conf file is very basic: "Lun 0 Path=/dev/sdb" (I've tried Type 
Fileio, Blockio, IOMode=wb,etc).



Has anyone else ever seen this?



Any thoughts would be greatly appreciated.

Thanks!

Brad
