Dear All,

We are using RHEL 6.6 and iscsi-initiator-utils-6.2.0.873-13 in our test 
environment.

we have modified following iscsi timeout and retry values in iscsi.conf,

node.session.timeo.replacement_timeout = 30 (previously 180)

node.session.initial_login_retry_max = 1 (previously 8, By Default)

node.session.err_timeo.abort_timeout = 5 (previously 15, By Default)

node.session.err_timeo.lu_reset_timeout = 10 (previously 30, By Default)
node.session.err_timeo.tgt_reset_timeout = 10 (previously 30, By Default)


As per our understanding, the above changes should get effective for 
iscsiadm commands just after restarting iscsi daemon. 

But, these are not getting effective until we execute the discovery 
command( iscsiadm -m discovery --type sendtargets -p x.x.x.x) after 
restarting iscsi daemon. 


Can someone please respond to my following queries:

1> As iscsi database(/var/lib/iscsi/nodes) resides at initiator side, 
restarting iscsi daemon should update the database(/var/lib/iscsi/nodes). 

Is the above understanding correct?

If not, is it always required to explicitly execute discovery command to 
make changes in iscsi.conf become effective ?

2> Is it possible to achieve the same without executing discovery command 
[Is there any other possible way] ?
