Now both paths are up again.
Note: Failing iSCSI paths may cause many log entries. When testing your
environment watch the size of /var/log/messages in different failure scenarios.
Placing /var/log on a separate filesystem helps to prevent a filled root
filesystem in case that logfiles grow too fast.
7.10 Linux iSCSI software initiator in RHEL4
At the time of writing this book, RHEL4 had no iSCSI software initiator support.
There is a statement about that in the Red Hat Enterprise Linux AS 4 Release
Notes: The initial release of Red Hat Enterprise Linux 4 does not include iSCSI
software initiator or target support. Support for iSCSI is being evaluated for
addition in a future update to Red Hat Enterprise Linux 4.
