Monitor and Manage
FibreChannel SAN Storage
The
esxcli storage san
commands
help administrators troubleshoot issues with I/O devices and
fabric, and include Fibre Channel, FCoE, iSCSI, SAS protocol statistics.
The commands allow you to
retrieve device information and I/O statistics from those device. You can also
issue Loop Initialization Primitives (LIP) to FC/FCoE devices and you can reset
SAS devices.
For FC and FCoE devices, you
can retrieve FC events such as
RSCN
,
LINKUP
,
LINKDOWN
, Frame Drop and
FCoE CVL
. The commands log a warning in the VMkernel
log if it encounters too many Link Toggling or frame drops.
The following example examines
and resets SAN storage through a FibreChannel adapter. Instead of fc, the
information retrieval commands can also use
iscsi
,
fcoe
, and
sas
.
- List adapter attributes.esxcli storage san fc list
- Retrieve all events for a Fibre Channel I/O device.esxcli storage san fc events get
- Clear all I/O Device Management events for the specified adapter.esxcli storage san fc events clear --adapter adapter
- Reset the adapter.esxcli storage san fc reset
