You must enable the fast fail and dynamic tracking attributes for hosts systems that run
an AIX 5.2 or later operating system.
Before configuring your host system to use these attributes, ensure that the host is
running the AIX operating system version 5.2 or
later.
To configure your host system to use the fast fail and dynamic tracking attributes follow
these steps.
Note: These steps need to be taken only on systems running AIX 6.1 or 5.2. The commands require
the fscsiX device to be in the defined
state.
- Issue the chdev -l fscsi0 -a fc_err_recov=fast_fail command to set the
Fibre Channel SCSI I/O Controller Protocol Device event error recovery
policy to fast_fail for each Fibre Channel adapter.
This example command is for adapter fscsi0.
Note: By default, dynamic tracking is enabled
on all systems running AIX
7.1.
- Issue the chdev -l fscsi0 -a dyntrk=yes command to enable dynamic tracking
for each Fibre Channel device.
This example command is for adapter fscsi0.
