How to Modify "replacement_timeout" of Already Discovered ISCSI Targets (Doc ID 1970699.1)

Last updated on NOVEMBER 20, 2016

Applies to:

Linux OS - Version Oracle Linux 5.0 to Oracle Linux 5.11 with Unbreakable Enterprise Kernel [2.6.39] [Release OL5 to OL5U11]
Linux x86-64

Goal

 "replacement_timeout" controls how long the iSCSI layer should wait for a timed-out path/session to reestablish itself before failing any commands on it. The default "replacement_timeout" value is 120 seconds.

By configuring a lower replacement_timeout, I/O is quickly sent to a new path and executed (in the event of a NOP-Out timeout) while the iSCSI layer attempts to re-establish the failed path/session.
