[ PCA/OVM ] How to modify iSCSI timeout Value (Doc ID 2443385.1)

Last updated on JULY 14, 2020

Applies to:

Private Cloud Appliance - Version 2.0.1 and later
Linux x86-64

Goal

In some situation, we may need to modify iSCSI timeout value to endure longer timeout, such as replacement_timeout or noop_out_timeout.

# To specify the length of time to wait for session re-establishment
# before failing SCSI commands back to the application when running
# the Linux SCSI Layer error handler, edit the line.
# The value is in seconds and the default is 120 seconds.
# Special values:
# - If the value is 0, IO will be failed immediately.
# - If the value is less than 0, IO will remain queued until the session
# is logged back in, or until the user runs the logout command.
node.session.timeo.replacement_timeout = 10

# To specify the time to wait for a Nop-out response before failing

# the connection, edit this line. Failing the connection will
# cause IO to be failed back to the SCSI layer. If using dm-multipath
# this will cause the IO to be failed to the multipath layer.
node.conn[0].timeo.noop_out_timeout = 5
