I have diskless server system, based on Centos 7. It receives targets specified in NIC bios and boots. The problem is - the system has very low iSCSI failure timeout, it fails in 5 seconds. Here is what i tried: editing parameters in /etc/iscsi/iscsid.conf:
node.session.timeo.replacement_timeout = 86400
node.conn[0].timeo.noop_out_interval = 0
node.conn[0].timeo.noop_out_timeout = 0
It does not help.
I specified same parameters with iscsiadm -T target -p ip -o update -n param_name -v value
It didn't help
I specified those parameters in dracut config (it argues on unknown command rd.iscsi.param=), still nothing.
Maybe someone can suggest something?
