It looks like one of your steps above left a session partially setup in the kernel. Why are you restarting iscsid and what command are you using to restart it? > > > Now, after above error has occurred, when we go to execute > operation1, operation 2, operation 3 but not operation 4. The core > is generated by iscsiuio. iscsiuio is only used for bnx2i, so it should not really come into play other than starting and stopping if that service is being restarted along with iscsid. You would need to attach the core so the qlogic or Red Hat developers can look at it. > > Can any one help me to understand the cause of the problem. > > > -- > You received this message because you are subscribed to the Google > Groups "open-iscsi" group. > To unsubscribe from this group and stop receiving emails from it, send > an email to [email protected] > <mailto:[email protected]>. > To post to this group, send email to [email protected] > <mailto:[email protected]>. > Visit this group at http://groups.google.com/group/open-iscsi. > For more options, visit https://groups.google.com/d/optout. -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
