Description Wayne Berthiaume 2005-01-14 18:38:52 UTC 
Description of problem:


Version-Release number of selected component (if applicable):
3.6.2

How reproducible:
always

Steps to Reproduce:
Server has three NICs, two are connected to the VLAN on two seperate 
subnets for iSCSI targets. There are two iSCSI arrays on the VLAN 
with two connections each one to one subnet and one to the other 
subnet. Therefore this is a multipathing configuration. There are 34 
LUNs assigned between the two storgae arrays to the one server. 
Therefore, the server sees two paths to each LUN for a yield of 68 
LUNs seen by the OS.

1.Installed RHEL U3 (lk 2.4.21-27.EL) updated to lk 2.4.21-27.0.1.EL
2.set up iSCSI with defaults in the iscsi.conf file
3.From a root prompt issue iscsi-ls -l
  
Actual results:
1) Only shows /dev/sda thru sdz all other LUNs are listed but 
no /dev/sd psuedo device names.
2) The enumeration is not correct. iscsi-ls() associates the psuedo 
device names incorrectly. Associating them with the first 26 LUNs in 
order that they are listed by iscsi-ls() output.
Expected results:
iscsi-ls() should report all the devices that are attached to an 
iscsi initiator and report them according to the initiator they are 
connected to correctly.

I'm a bit confused about what you mean in item 2.  Could you provide the
erroneous output for me?

Created attachment 111094 [details]
Initial patch to fix the > 26 lun bug

Here's an initial stab at a fix for this one:
allow the device name to be 4 characters, but verify the 4th character is an 
alphabetic character so we don't get /dev/sda1 in the output

This should catch the double letter sdxx devices, but avoid the sdx1 partitions
Comment 6 AJ Lewis 2005-02-16 18:19:18 UTC 
There is an i386 rpm at
http://people.redhat.com/alewis/rpms/iscsi-initiator-utils-3.6.2-6.i386.rpm that
includes the patch from comment #5.  Please try this and see if it fixes the
problem.  Note that this RPM is unsupported.
Comment 7 Wayne Berthiaume 2005-02-17 23:44:39 UTC 
I was unable to install the rpm. I tried -Uvh and it complained of a conflict 
with the original iscsi init script. To install the package I erased the 
original package then installed, with -ivh, the new package. I receive this 
error when I try to start the iscsi driver with a "service iscsi start" command:

Comment 8 AJ Lewis 2005-02-22 17:34:13 UTC 
What is the kernel version you are using?
Comment 9 Wayne Berthiaume 2005-02-28 16:06:02 UTC 
The kernel is 2.4.21.-27.EL SMP x86_64.
Comment 10 AJ Lewis 2005-02-28 16:08:38 UTC 
Well, that explains it - the rpm i posted on my peoples page is for x86, not
x86_64!  I'll put an x86_64 rpm up as well.
Comment 11 AJ Lewis 2005-02-28 16:11:06 UTC 
x86_64 rpm is at:
http://people.redhat.com/alewis/rpms/iscsi-initiator-utils-3.6.2-6.x86_64.rpm
Comment 12 Wayne Berthiaume 2005-02-28 22:41:10 UTC 
I've downloaded it and will update with a new status.
Comment 13 AJ Lewis 2005-03-07 15:08:01 UTC 
Any status updates from people trying this?
Comment 14 Wayne Berthiaume 2005-03-28 18:49:52 UTC 
AJ, I've tested the -i386 package you posted and it worked properly. 
Thank you.
Comment 15 Heather Conway 2005-04-08 15:24:55 UTC 
Testing is in process
Comment 16 Wayne Berthiaume 2005-04-08 16:19:02 UTC 
Hi AJ.
    I've tested the RHEL U5 beta for this issue and it appears to be corrected.
Thank you.
Wayne.
