Appendix D Firmware and Device Driver Error Messages D-13
The above message indicates that the loop is cycling between
ONLINE
and
OFFLINE
.
Under a variety of circumstances, the Fibre Channel link may appear to the host
adapter to have entered an inoperable state. This condition is usually temporary.
The Fibre Channel link can appear to go offline due to the following:
■
A burst of errors occur on the fiber optic cable. In this case, the
OFFLINE
messages are usually followed by an
ONLINE
message shortly afterward.
■
A fiber optic cable is disconnected from a host adapter, a disk array, or a hub.
■
A connected disk array is powered off..
In addition, the failure of one or more of the following devices can also cause the
messages:
■
GBIC in a host adapter, a hub, or a disk array
■
Fiber optic cable
■
Interface board
■
Host adapter
Following a link
OFFLINE,
any pending I/O operations to the disk array will be
held by the driver for about one to two minutes. This is done so that pending
operations can be completed if the link returns to an operable state. However, if the
link does not transition from
OFFLINE
to
ONLINE
during that time, the driver will
fail the I/O operations associated with the formerly connected disk array.
It is normal to see the
ONLINE
message for each connected disk array when the
system is booting.
Peripheral devices on the Fibre Channel (like the disk array) can cause the above
message to be displayed on the system console/syslog under certain circumstances.
