Description Saggi Mizrahi 2013-07-11 09:10:38 EDT

Description of problem:
In order to refresh targets iscsiadm pokes all the devices and targets for updates sequentially. If one is not responding iscsiadm will block forever and not refresh the rest of the targets.

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


How reproducible:
101%

Steps to Reproduce:
1. Connect to a couple of targets
2. Set the firewall to drop packets going to a specific target
3. run: iscsiadm -m session -R
4. profit

Actual results:
iscsiadm gets stuck in D state and the rest of the targets remain unscanned.

Expected results:
iscsiadm should be killable and the all targets should be updated.
