Yes, generally best practices require that each component of your two paths between initiator and target are redundant. This means that, in the case of networking, you want to be on different subnets, served by different switches. You also want two different NICs on your initiator, if possible, although many times they are on the same card. But, obviously, some points are not redundant (like your initiator or target). > > What iSCSI target are you using? > > Regards, > Don > > On Tue, Jun 30, 2020 at 9:00 AM Amit Bawer <[email protected]> wrote: > >> [Sorry if this message is duplicated, haven't seen it is published in the >> group] >> >> Hi, >> >> Have couple of question regarding iscsiadm version 6.2.0.878-2: >> >> 1) Is it safe to have concurrent logins to the same target from different >> interfaces? >> That is, running the following commands in parallel: >> >> iscsiadm -m node -T iqn.2003-01.org.vm-18-198.iqn2 -I default -p >> 10.35.18.121:3260,1 -l >> iscsiadm -m node -T iqn.2003-01.org.vm-18-198.iqn2 -I default -p >> 10.35.18.166:3260,1 -l >> >> 2) Is there a particular reason for the default values of >> node.conn[0].timeo.login_timeout and node.session.initial_login_ >> retry_max? >> According to comment in iscsid.conf it would spend 120 seconds in case of >> an unreachable interface login: >> >> # The default node.session.initial_login_retry_max is 8 and >> # node.conn[0].timeo.login_timeout is 15 so we have: >> # >> # node.conn[0].timeo.login_timeout * node.session.initial_login_retry_max >> = >> # 120 >> seconds >> >> >> Thanks, >> Amit >> >> -- >> 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]. >> To view this discussion on the web visit >> https://groups.google.com/d/msgid/open-iscsi/cc3ad021-753a-4ac4-9e6f-93e8da1e19bbn%40googlegroups.com >> >> <https://groups.google.com/d/msgid/open-iscsi/cc3ad021-753a-4ac4-9e6f-93e8da1e19bbn%40googlegroups.com?utm_medium=email&utm_source=footer> >> . >> > -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
