Hi,
Recently I was trying to use open-iscsi of SuSE10 on VMware virtual
machine.
But when I trying to login to iscsi target, the iscsiadm hung for a
very long time. Sometimes the process returns "iscsiadm cannot connect
to iscsid...", sometimes I have to kill it.
But after I kill that iscsiadm process, I can find the session by
using iscsiadm -m session.
Is there anybody have any ideas on this? Thanks in advance.
Here's some detail information:
The OS: SuSE10

Then I use this:
# iscsiadm -m node -r 68a68a -l
iscsiadm: caught SIGINT, exiting...
But the result is:
# iscsiadm -m session

One thing I noticed, that in the dmesg

Here's my iscsc configuration ( I cut the comments ):
