Description Lubomir Kundrak 2008-02-05 15:11:34 EST 
Description of problem:

Now that anaconda relies on HAL for disks enumeration, it has become important
for hal to see the drives accessed via iSCSI. It is not the case now.

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

kernel-2.6.24-9.fc9.i686
hal-0.5.10-4.fc9.i386

How reproducible:

Allways

Steps to Reproduce:
1. Set up a scsi target (netbsd-iscsi or scsi-initiator-utils packages might
come handy, or kernel-mode iscsitarget from livna)
2. Discover the target with iscsiadm -m discovery -m st -p localhost
3. Log in with iscsiadm -m node --login
4. See what does hald do
  
Actual results:

Expected results:

See the target in hal device tree

Additional info:

Please reassign to kernel if pertinent. I really can not tell if this is hal or
kernel issue. Thanks!
Comment 1 David Zeuthen 2008-02-14 11:16:44 EST 
Can't have this in HAL; anaconda need to do something different.
Comment 2 David Zeuthen 2008-02-14 15:05:48 EST 
OK, Jeremy explained exactly what is needed. I'll add this Monday. Thanks.
Comment 3 Lubomir Kundrak 2008-02-20 08:23:06 EST 
May I ask... any progress on this?
Comment 4 David Zeuthen 2008-02-23 13:40:05 EST 
Pending; was bogged down with other important stuff. Already talked to pjones to
get access to iSCSI targets. Hoping to look at it next week.
Comment 5 David Zeuthen 2008-03-03 20:54:33 EST 
This is now done.
