I/O Switchover Takes a Long Time When an iSCSI Link Is Faulty

Dear Mumammad,

Have a good day.

The default iSCSI timeout duration is 120s. After an iSCSI link is faulty, the I/O switchover duration is longer than 120s.

The I/O switchover duration is determined by the connection fault detection duration of the iSCSI initiator of the host. You can modify the default iSCSI timeout duration on the host based on service requirements.

For example:

The iSCSI configuration file on a Linux host is stored in the /etc/iscsi.conf or /etc/iscsi/iscsid.conf file.

Change the value of node.session.timeo.replacement_timeout to 120 in the configuration file.

Thanks.
